A study was conducted to evaluate a high pressure spray (HPS) with water as an alternative to trimming to remove gastrointestinal contamination on poultry carcasses and improve microbiological quality. The study was conducted under commercial conditions in 5 slaughter plants with one plant presenting approximately 5% of carcasses with visible gastrointestinal contamination (VGC), and the others showing approximately 12% of VGC. In all 5 plants, carcasses were sampled from the slaughter line and separated into 6 groups corresponding to 3 different treatments: A) carcasses with VGC before and after trimming; B) carcasses with VGC before and after HPS; and C) carcasses with no VGC before and after HPS. At the end of Trial A and prior to Trials B and C, an HPS equipment was installed before the end of the slaughter line. The HPS equipment was operated with 10 kgf/cm² of pressure and 1.5 L of potable water per carcass. Carcasses were analyzed using a rinsing procedure, and the following microbiological parameters were evaluated: the prevalence of Salmonella and Campylobacter, the abundance of Escherichia coli (EC), Enterobacteriaceae (EB), and the Total Viable Count (TVC). Salmonella was found in all plants at a prevalence ranging from 0.8% (plant 1) to 17.3% (plant 5), and the difference between plants was significant (P < 0.05%). The prevalence of Campylobacter ranged from 2.1 (plant 1) to 18.6% (plant 4) (P < 0.05%). The prevalence of Campylobacter was similar in plants 2, 3, and 5, and a significant difference (P < 0.05%) was observed compared to plants 1 and 4. In all plants, the EC, EB, and TVC counts did not show a significant difference (P > 0.05%) in any treatments. These results demonstrate that HPS with water is an alternative method for removing VGC and improving or maintaining the microbiological quality and safety of broiler carcasses.
