RESUMEN

Acrylamide (AA) is a contaminant resulting from the Maillard reaction and classified by the International Agency for Research on Cancer (IARC) as a probable carcinogen in Group 2A, with proven neurotoxic effects on humans. European Union (EU) Regulation No. 2017/2158 is currently in force, which establishes measures meant to reduce AA levels in food and sets reference values, but not legal limits, equal to 40 and 150 µg/kg AA in processed cereal-based foods intended for infants and young children and in biscuits and rusks, respectively. For this reason, sixty-two baby foods were analyzed using ultra-high performance liquid chromatography with diode array detector and quadrupole time-of-flight mass spectrometry (UHPLC-DAD-Q-TOF/MS) to check whether industries were complying with these values, even though AA control is not legally mandatory. In total, 14.5% of the samples exceeded the reference values; these were homogenized chicken products (211.84 ± 16.53, 154.32 ± 12.71, 194.88 ± 7.40 µg/kg), three biscuits (276.36 ± 0.03, 242.06 ± 0.78, 234.78 ± 4.53 µg/kg), a wheat semolina (46.07 ± 0.23 µg/kg), a homogenized product with plaice and potatoes (45.52 ± 0.28 µg/kg), and a children's snack with milk and cocoa (40.95 ± 0.32 µg/kg). Subsequently, the daily intake of AA was estimated, considering the worst-case scenario, as provided by the consumption of homogenized chicken products and biscuits. The results are associated with margins of exposure (MOEs) that are not concerning for neurotoxic effects but are alarming for the probable carcinogenic effects of AA.

RESUMEN

Optimal nutrition during infancy is critical given its influence on lifelong health and wellbeing. Two novel methods of infant complementary feeding, commercial baby food pouch use and baby-led weaning (BLW), are becoming increasingly popular worldwide. Household food insecurity may influence complementary feeding practices adopted by families, but no studies have investigated the use of BLW and baby food pouches in families experiencing food insecurity. The First Foods New Zealand study was a multicentre, observational study in infants 7.0-9.9 months of age. Households (n = 604) were classified into one of three categories of food insecurity (severely food insecure, moderately food insecure, and food secure). The use of complementary feeding practices was assessed via a self-administered questionnaire, both at the current age (mean 8.4 months) and retrospectively at 6 months. Mothers experiencing severe food insecurity had 5.70 times the odds of currently using commercial baby food pouches frequently (≥5 times/week) compared to food secure mothers (95% CI [1.54, 21.01]), reporting that pouches were 'easy to use' (89%) and made it 'easy to get fruits and vegetables in' (64%). In contrast, no evidence of a difference in the prevalence of current BLW was observed among mothers experiencing moderate food insecurity (adjusted OR; 1.28, 95% CI [0.73, 2.24]) or severe food insecurity (adjusted OR; 1.03, 95% CI [0.44, 2.43]) compared to food secure mothers. The high prevalence of frequent commercial baby food pouch use in food insecure households underscores the need for research to determine whether frequent pouch use impacts infant health.

RESUMEN

Despite growing concerns over the increasing popularity and health impact of commercial foods for infants and toddlers, no nutrition or promotional guidelines currently exist for the United States. In 2022, the WHO Regional Office for Europe published a nutrient and promotion profile model (NPPM) to provide guidance and regulation for commercially produced infant and toddler foods. This study assessed the nutritional and promotional profile of infant and toddler foods (6-36 months of age) collected from the top 10 grocery chains in 2023. Products were assessed against the WHO NPPM nutritional and promotional requirements. The type and number of claims across packaging type were also assessed. Of the 651 products examined, 60% failed to meet the nutritional requirements of the NPPM, and 0% met the promotional requirements. Almost 100% of products had at least 1 claim on-pack that was prohibited under the NPPM, with some products displaying up to 11 prohibited claims. Snack-size packages had the lowest compliance with nutrient requirements. These findings highlight that urgent work is needed to improve the nutritional quality of commercially produced infant and toddler foods in the United States. The high use of prohibited claims also suggests the need to regulate the type and number of claims allowed on-pack.

RESUMEN

This study reports for the first time the phenomenon of supramolecular solvent formation based on alkyl polyglucoside as an amphiphile and primary alcohol as a coacervation agent. The physical properties (density, kinematic viscosity, phase diagram for ternary system) of the supramolecular solvent were investigated, and a mechanism for its formation was proposed. A green and simple microextraction procedure for preconcentration and determination of phthalates in baby foods packaged in plastic packaging was developed as proof-of-concept example. The microextraction procedure assumed separation of analytes from solid phase sample in micellar solution of decyl glucoside and in situ formation of supramolecular solvent for analytes preconcentration after addition of n-heptanol. The determination of phthalates in obtained extracts was implemented by high-performance liquid chromatography with UV-Vis detection. The limits of detection, calculated from a blank test based on 3σ, were determined to be 10 µg kg-1 for dimethyl phthalate, diethyl phthalate, di-n-butyl phthalate, and di-n-octyl phthalate. The developed procedure did not require filtration of sample suspension, and assumed the use of green and biodegradable substances for the supramolecular solvent formation across a wide pH range.

RESUMEN

In response to the need for better guidance and regulation for commercially produced infant and toddler foods and beverages, the WHO Regional Office for Europe published a Nutrient and Promotion Profile Model (hereafter NPPM) in 2022. This study assessed the nutritional and promotional profile of infant and toddler foods (for ages 6-36 months) sold in Australian supermarkets in 2022 using the NPPM. The main types of claims used for product promotion were also examined and results were presented by category and by packaging type. Nutrient and claims data were extracted for commercially produced infant and toddler products from The George Institute's FoodSwitch database. Products were classified according to NPPM food categories and assessed against relevant nutritional and promotional requirements. Of the 309 products examined, 78% failed to meet the nutritional requirements of the NPPM, and 0% met the promotional requirements. Every product had at least one claim on-pack that was prohibited under the NPPM, with some products displaying up to 21 different claims on-pack. Pouches had the highest number of prohibited claims of all packaging types. Findings highlight that urgent work is needed to improve the nutritional quality of commercially produced infant and toddler foods in Australia. The high use of prohibited claims also suggests the need to regulate the type and number of claims that can be made on-pack, as parents and carers could easily be misled by the deceptive labelling that is currently allowed to be displayed.

RESUMEN

Food safety is an important issue to protect humane health and improve the life quality. Hence, analysis of the possible contaminants in food samples is essential. A rapid and efficient vortexed-assisted dispersive µ-solid-phase extraction coupled with gas chromatography-mass spectrometry was proposed for simultaneous separation/preconcentration and determination of five commonly used organophosphorus pesticides. Reduced graphene oxide decorated NiCo2(OH)6 nanoflowers as a novel nanostructure was synthetized and introduced for separation of the target pesticides from the wheat flour, rice flour, and baby food cereal samples. The characterization of the nanoflowers was accomplished by SEM-EDX, XRD, and FT-IR techniques. The main factors including pH, the amount of nanoflower, the volume of sample solution, salt concentration (ionic strength), desorption conditions (i.e. desorption solvent type and volume, and desorption time) on the pesticides extraction efficiencies were inquired using matrixed match method. Applying the optimum conditions, the linearity of 0.100-500.000 µg kg-1, LODs and LOQs in the range of 0.03-0.04 µg kg-1 and 0.1 µg kg-1 for the studied food samples were obtained. The repeatability (intra-day precision (n = 5)) of ≤ 2.0 % and reproducibility (inter-day precision, days = 5, n = 3) of ≤3.1 % and were appraise at three concentration levels (10, 50 and 100 µg kg-1 of each analyte). High relative recoveries of 90.0-99.3 % ascertained high potential of the presented method for complex matrix analysis.

RESUMEN

The analysis of pesticide residues and mycotoxins in baby food demands exceptionally low limits of quantitation, necessitating the use of highly sensitive instruments capable of conducting trace analyses. High-resolution instruments typically fail to detect such low levels. However, the latest advancements in liquid time-of-flight technology, when coupled with ion trapping, enable ion enrichment, thereby improving detection levels. This allows for the analysis of these substances at low concentration levels, benefiting from enhanced mass accuracy. Additionally, the use of mass accuracy data helped eliminate matrix interferences, thereby enabling high-confidence identification. We developed a multi-residue method to analyse 219 pesticide residues and 9 mycotoxin residues in baby food matrices. Utilizing a QuEChERS-based extraction method, the samples were then analysed using an LC-ZenoTOF 7600 system with mass window screening acquisition. For pesticides, the limit of quantitation was 0.001-0.003 mg/kg for 81 % of the evaluated compounds, 0.005 mg/kg for 13 %, 0.010 mg/kg for 4 % and 0.020-0.030 for 2 %; good linearities were obtained at these levels. Apparent recoveries were evaluated at 0.003, 0.005, and 0.010 mg/kg. At the lowest recovery level, 93 % of compounds showed recoveries between 70 and 120 %. The rest of the compounds were in the range of 63-129 %, with relative standard deviation values below 20 %. For mycotoxins, the limits of quantitation ranged from 0.0001 to 0.100 mg/kg, with matrix-matched concentrations assessed within this range. Recoveries were evaluated at low concentration range (0.001-0.003 mg/kg) and high range (0.020-0.050) with apparent recoveries values between 92 and 140 %. Finally, a total of 31 commercial baby food samples were analysed using this method. The results indicated that 16 samples contained pesticide residues, while two samples were found to have mycotoxins.

RESUMEN

It is recommended that infants are introduced to complementary foods from 6 months old, moving from a solely milk diet to eating a family diet by 12 months old. Although home cooking of family foods is recommended, a rapidly growing market producing baby food products (BFP) such as jars, pouches and snacks has developed. These are often accompanied by marketing claims around nutritional, health and developmental impacts despite research highlighting high sugar content. Although numerous studies have explored drivers of infant formula choice and use, little research has examined the drivers of BFP use. This study used an online survey for United Kingdom parents of infants aged 4-12 months to explore use of BFP alongside perceptions and drivers to purchase products. Overall, 271 parents participated (173 used BFP and 98 did not), with a descriptive analysis of closed items and a thematic analysis for open ended text conducted. The top motivators for using BFP were convenience, time saving, and baby's perceived enjoyment of products. The most purchased puree was fruit based and the most purchased baby snacks were vegetable puffs/sticks, with snack purchases being more common than purees in this sample. Aspects such as perceived healthiness drove choice, with snack foods being seen to enhance self-feeding skills, appetite regulation and motor development. Those who did not use BFP did not trust them and preferred to feed their baby home cooked foods. The findings are important for professionals working with parents, to support them through the transition to solid foods, particularly around raising awareness of marketing techniques and how to check content of foods to make a more informed choice.

RESUMEN

Iron deficiency in infants can impact development, and there are concerns that the use of baby food pouches and baby-led weaning may impair iron status. First Foods New Zealand (FFNZ) was an observational study of 625 New Zealand infants aged 6.9 to 10.1 months. Feeding methods were defined based on parental reports of infant feeding at "around 6 months of age": "frequent" baby food pouch use (five+ times per week) and "full baby-led weaning" (the infant primarily self-feeds). Iron status was assessed using a venepuncture blood sample. The estimated prevalence of suboptimal iron status was 23%, but neither feeding method significantly predicted body iron concentrations nor the odds of iron sufficiency after controlling for potential confounding factors including infant formula intake. Adjusted ORs for iron sufficiency were 1.50 (95% CI: 0.67-3.39) for frequent pouch users compared to non-pouch users and 0.91 (95% CI: 0.45-1.87) for baby-led weaning compared to traditional spoon-feeding. Contrary to concerns, there was no evidence that baby food pouch use or baby-led weaning, as currently practiced in New Zealand, were associated with poorer iron status in this age group. However, notable levels of suboptimal iron status, regardless of the feeding method, emphasise the ongoing need for paying attention to infant iron nutrition.

RESUMEN

Ochratoxin A (OTA), zearalenone (ZEN), and deoxynivalenol (DON) are mycotoxins whose exposure is associated with various adverse health effects, including cancer and renal disorders, estrogenic effects, and immunosuppressive and gastrointestinal disorders, respectively. Infants (<2 years) are the most vulnerable group to mycotoxins, representing a unique combination of restricted food consumption types, low body weight, lower ability to eliminate toxins, and more future years to accumulate toxins. This study aimed to estimate the infant́s exposure to OTA, DON, and ZEN due to the consumption of milk formula and baby cereals in Chile. Milk formula samples (n = 41) and baby cereals (n = 30) were collected and analyzed using commercial ELISA kits for OTA, DON, and ZEA determination. Exposure was assessed by the Estimated Daily Intake (EDI) approach (mean and worst-case scenario, WCS) with the levels found in a modified Lower Bound (mLB) and Upper Bound (UB); ideal consumption (<6m, 7-12 m, and 13-24 m); adjusted by the weight of each group. The risk was estimated by comparing the EDI with a reference tolerable daily intake or by the margin of exposure (MOE) in the case of OTA. DON and OTA occurrence in infant formula were 34 % and 41 %, respectively. The co-occurrence between these mycotoxins was 22 %. Mycotoxin contents were below LOQ values except for OTA determined in one sample (0.29 ng/ml). No milk formulae were contaminated with ZEN. In the case of baby cereals, the occurrences were 17 % for OTA, 30 % for DON, and 7 % for ZEN, all below LOQ. Co-occurrence was seen in two samples between ZEN and OTA. According to exposure calculations, the MOE for OTA was less than 10,000 in all models for milk formula between 0 to 12 months of age and in the UB and WCS for cereal consumption. Health concerns were observed for DON in the WCS and UB for milk consumption in all ages and only in the UB WCS for cereal consumption. Considering the high consumption of milk formula in these age groups, regulation of OTA and other co-occurring mycotoxins in infant milk and food is strongly suggested.

RESUMEN

When selecting commercial baby food, parents make the initial decision, but the baby's approval ultimately determines the likelihood of repurchasing. However, discerning what babies prefer and enjoy can be challenging for food developers because babies cannot verbally express their preferences. To gain insight into the decision-making process of parents when selecting food for their infants, this study aims to examine: 1. the reasons behind choosing commercial baby food purees, 2. the sensory factors that influence baby acceptance, and 3. how accurately parents can predict baby acceptance. Two experiments were performed. The first investigated the purchasing decisions and underlying reasons of 100 parents, who evaluated 14 different commercial baby food purees. Second, a study was conducted involving 40 parents and their babies (8-30 months) who evaluated a set of 9 baby food purees in two different settings: 1. the parents tasted the puree, and 2. the babies ate the product at home. The results of the first experiment were analyzed using regression trees to uncover the hierarchy of factors that influenced parental decisions. Two negative factors, product unfamiliarity, and high price, were the most important factors leading to parental rejection. Healthiness, tastiness, satiety and good price were the reasons that contributed to a final positive purchasing decision. In the second experiment, the influence of the sensory attributes on babies' perception were determined through a PLS-regression model. The findings revealed that the chicken flavor and vegetable flavors, such as potato, onion, peas, and legumes, positively correlated with infants' liking, whereas fish, tomato, and acidic flavors had negative implications. The texture attributes of sandiness and stickiness had a positive effect on baby liking, whereas smoothness had a negative impact. The results of the regression model based on the predictions revealed that flavor attributes that drive liking and disliking for babies coincided with their parents. However, the texture attributes did not match. Parents considered texture attributes, specifically creaminess and smoothness, as relevant and positive. However, these texture attributes did not affect or slightly decrease babies' acceptance that was positively affected by sandiness and stickiness.

RESUMEN

Lead (Pb) and mercury (Hg) are neurodevelopmental toxicants that pose risks to cognitive and behavioral health. Given early childhood's vulnerability to these metals, understanding their sources and pathways of exposure during infancy is crucial for public health. During the weaning process, infants may be exposed to metals through the baby food they consume. We aimed to assess metal exposure through homemade weaning foods by analyzing 288 samples consumed by 157 Korean infants aged 6-, 9-, 12-, 15-, and 24-27 months. Pb was detected in 65 % of samples, with levels reaching up to 169 ng/g. Notably, 58 % exceeded the Maximum Level (ML) of 10 ng/g, with a median concentration of 14.7 ng/g fresh weight. Total Hg was found in 88 % of samples, with a median concentration of 4.56 ng/g fresh weight. Estimated median daily intakes of Pb and Hg were 0.29 and 0.09 µg/kg/d, respectively. Considering a benchmark dose for Pb (0.5 µg/kg/d by EFSA), 94 % (the margin of exposure <10) of all age groups was estimated to have a potential health concern associated with homemade baby food consumption. For Hg, only 6 % exceeded a hazard quotients of 1 compared to a provisional tolerable weekly intake for Hg (4 µg/kg/week by WHO). This study marks the first direct assessment of daily Pb and Hg intake through homemade baby food among Korean infants. Our findings underscore the urgent need for heightened awareness regarding metal exposure through homemade baby food.

RESUMEN

The aim of the present research was the development and validation of a selective and reliable method for the indirect and direct determination of acidic herbicide glucosides. Enzymatic deconjugation was investigated as a mild alternative to harsh alkaline hydrolysis. Various enzymatic options for deconjugation were exploited. One out of nine tested specific enzymes proved to be practical and repeatable for different matrices and concentration ranges, leading to the complete deconjugation of the glucosides. The method was validated according to the SANTE/11312/2021 guideline for cereals and oilseeds and for a rice-based infant formula. Additionally, for four acidic herbicide glucosides available on the market, a quantitative method for direct determination of the intact glucosides was optimized and validated. In both methods, the average recoveries were within 70-120%. The limits of quantification (LOQ) achieved were 10 µg kg-1 and 2.5 µg kg-1 for the intact glucosides and the free acids in cereal and oilseeds. For the rice-based infant formula, the LOQ was 1 µg kg-1 (3 µg kg-1 for dichlorprop). To confirm its applicability, the deconjugation approach was tested for fifteen samples (cereals, oilseeds, and citrus) with incurred residues. Comparisons were made between the method without deconjugation, and two methods with deconjugation, the here proposed enzymatic deconjugation and the more commonly used alkaline hydrolysis. The inclusion of enzymatic deconjugation during sample preparation led to an increase up to 2.7-fold compared to analysis without deconjugation. Enzymatic deconjugation resulted in comparable results to alkaline hydrolysis for 13 out of 15 samples.

RESUMEN

Although concern is frequently expressed regarding the potential impact of baby food pouch use and Baby-Led Weaning (BLW) on infant health, research is scarce. Data on pouch use, BLW, energy intake, eating behaviour and body mass index (BMI) were obtained for 625 infants aged 7-10 months in the First Foods New Zealand study. Frequent pouch use was defined as ≥5 times/week during the past month. Traditional spoon-feeding (TSF), "partial" BLW and "full" BLW referred to the relative proportions of spoon-feeding versus infant self-feeding, assessed at 6 months (retrospectively) and current age. Daily energy intake was determined using two 24-h dietary recalls, and caregivers reported on a variety of eating behaviours. Researchers measured infant length and weight, and BMI z-scores were calculated (World Health Organization Child Growth Standards). In total, 28% of infants consumed food from pouches frequently. Frequent pouch use was not significantly related to BMI z-score (mean difference, 0.09; 95% CI -0.09, 0.27) or energy intake (92 kJ/day; -19, 202), but was associated with greater food responsiveness (standardised mean difference, 0.3; 95% CI 0.1, 0.4), food fussiness (0.3; 0.1, 0.4) and selective/restrictive eating (0.3; 0.2, 0.5). Compared to TSF, full BLW was associated with greater daily energy intake (BLW at 6 months: mean difference 150 kJ/day; 95% CI 4, 297; BLW at current age: 180 kJ/day; 62, 299) and with a range of eating behaviours, including greater satiety responsiveness, but not BMI z-score (6 months: 0.06 (-0.18, 0.30); current age: 0.06 (-0.13, 0.26)). In conclusion, neither feeding approach was associated with weight in infants, despite BLW being associated with greater energy intake compared with TSF. However, infants who consumed pouches frequently displayed higher food fussiness and more selective eating.

RESUMEN

This study examined and compared the nutritional quality and degree of naturalness between baby biscuits (<3 years), children biscuits (>3 years), and adult biscuits. Mintel's Global New Products Database was searched for "Baby Biscuits & Rusks" and "Sweet Biscuits/Cookies" (re)launched between July 2019 and July 2022 in four European countries (Germany, the Netherlands, Spain, and the United Kingdom), which resulted in 1280 products to be analyzed. Nutritional quality was measured by means of nutrient values per 100 g, and baby biscuits were assessed for compliance with the World Health Organization's latest Nutrient and Promotion Profile Model (NPPM). Degree of naturalness was measured using the food naturalness index (FNI). Baby biscuits had the best nutritional quality and were the most natural as compared to children and adult biscuits, but their energy density and sugar content require further attention. Nutritional quality was comparably poor in children and adult biscuits, and children biscuits were the least natural of the three groups. The NPPM requirements of not adding any free sugar at all to baby biscuits may drive parents to purchase alternative sweeter biscuits originally formulated and meant for children and adults. Reasonable regulations are needed to support product (re)formulations and to improve the current market food offer for babies and children.

RESUMEN

This study determines the levels of 49 persistent organic pollutants which were grouped into polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and hexabromocyclododecanes (HBCDDs), in infant formula and varieties of baby food. The analyzed samples (n = 80) came from stores all over Poland. The presence of PCDD/F, PCDD/F/PCB and non dioxin-like (ndl)-PCB congeners above the maximum levels stipulated in Commission Regulation (EU) No 1259/2011 was not detected in any sample. The determined average content of PCDD/Fs/dl-PCBs in the tested baby foods was in the range of 4-10 % of the maximum level, and content of ndl-PCBs was in the range of 2-6 % of the maximum level. Despite these low levels of dioxins, furans, and PCBs, a risk analysis assuming weekly consumption of the recommended food intake showed exceedances of the tolerable weekly intake (TWI). The content of flame retardants was low in all examined categories of food for children and infant formula. The lower-bound concentration of the sum of HBCDD isomers (LB ∑HBCDDs) ranged from below the limit of quantification (LOQ) to 0.0313 ng/g w.w. and the concentration of ∑PBDEs was in a 0.001-1.014 ng/g w.w. range. Neither infant formula nor baby food contributed considerably to infant exposure to HBCDDs or PBDEs. Our research indicates that the safe exposure thresholds for dioxins and PCBs in foods for infants and young children may be too high and perhaps it may be necessary to amend the legislation setting acceptable limits for baby food. It seems reasonable to introduce a recommendation on the frequency of food consumption for children and the control of raw materials for food production, in particular fish and cow milk, should be a permanent control point in the food safety assurance system.

RESUMEN

Background: In recent years, there has been an increase in the variety and consumption of commercial infant and toddler food products. Aim: The aim of this study is to evaluate the nutritional profiles of commercial infant and toddler food products sold in Turkey. Methods: A cross-sectional survey of the nutritional composition of products available at in-store and online supermarkets in Turkey was derived from the nutritional information panel on the product label or information provided on manufacturer websites in March 2023. The targeted age group, package type, serving size, ingredients list, and nutrition information (energy [kcal], protein [g], total fat [g], carbohydrate [g], dietary fiber [g], total sugar [g], and sodium [mg] per 100 g) were recorded. Results: Of the 189 products identified, more than 90% (n = 47) of the first foods were fruit-based, while 2% (n = 4) contained only vegetables. Almost half of the products (n = 89, 49%) contained added sugar or sweeteners, 41 (22%) had added sugar, and 1 in 3 products (n = 68, 36%) had sugar from fruit-based sources. One in 10 products (n = 18, 9.5%) contained added salt while 40% of the products (n = 76) were above the WHO Europe sodium standards. Almost half of the products (n = 6, 46%) targeting the 12 months older age group were pureed foods using squeeze pouch packaging. Conclusions: The majority of commercial infant and toddler food products did not adhere to nutrition guidelines. There is a need for stronger composition standards for commercial infant and toddler food products by reducing sugar and sodium content, reducing the use of fruits and sweet vegetables, and increasing the variety of products containing different types of vegetables.

RESUMEN

BACKGROUND: The infant population is particularly sensitive, so the risk posed by their diet must be analyzed. The aims of the present study were (i) to determine the contents of 38 elements in 159 samples of ready-to-eat baby food sold in Spain and (ii) to estimate the dietary intakes and risk assessments of these elements in name brands and store brands in infants ranging between 6 and 12 months of age. METHODS: A list of essential, non-essential/toxic elements, rare earth elements (REEs), and other hi-tech-related elements that are currently considered as emerging environmental pollutants were measured in ready-to-eat baby foods by ICP-MS. RESULTS: Fish purees showed the highest concentrations of mercury (28.1 ng/g) and arsenic (346.2 ng/g). The levels of manganese, molybdenum, and chromium exceed the adequate intake, being higher in the case of store brands. The acute hazard index was above 1 for molybdenum and manganese. A risky consumption of thallium and mercury was observed, being higher among name brands. The risk associated with the consumption of REEs was low, although its presence should be highlighted. CONCLUSIONS: This is the first time that these chemical elements have been measured in ready-to-eat purees for babies. The presence of some of them, such as mercury, should be sufficient to monitor the levels of these contaminants in food intended for such a sensitive population as children.

RESUMEN

The U.S. Food and Drug Administration released proposed lead (Pb) action levels for foods intended for babies and young children in January 2023 based on the agency's interim reference value of 2.2 µg/day for dietary Pb. Since the 1980s, biokinetic models have estimated blood lead levels (BLLs) associated with environmental contamination, but their use in food safety assessment has been limited. We compared three recent biokinetic models (IEUBK Model, ICRP Model Version 5, and AALM) to develop insights on contributors to variability in potential exposures to Pb in consumer baby food products. While modest variation was observed for babies, the predictions trended to convergence for children aged 3 and older, approaching the U.S. FDA dietary conversion factor of 0.16 µg Pb/dL blood per µg Pb intake/day. We applied the IEUBK model in a probabilistic exposure assessment framework characterizing the distribution of Pb in soil, dust, water, and food intake in the United States. Soil and dust were the primary contributors to variance in infant BLLs, while food and water contributed <15% combined. Thus, reductions in upper-bound soil and dust concentrations will be necessary before achieving appreciable reductions in the frequency of BLLs greater than the BLRV of 3.5 µg/dL.
