Surveillance of Amyloid Deposition and Bacterial Contamination in Chicken Liver from Meat Market

Abstract

From the standpoint of poultry meat hygiene, amyloid deposition and bacterial contamination in livers of 197 mature white layer chickens from a slaughterhouse and 100 young broiler breeder chickens from 5 different retail butcher shops were examined. Amyloid deposition was detected in 1 liver from 2-years-old layer using alkaline Congo red staining and immunohistochemical examination, but no amyloid deposition was observed in 100 livers from young broiler. Total bacterial counts in the chicken livers were examined using nutrient, desoxycholate hydrogen sulfate and mCCDA agar plates, but no close relationship between amyloid deposition and bacterial contamination (counts and species) was observed in this study. These results suggest there is low incidence of systemic amyloid deposition in chicken liver from meat market.
