Chicken carcass microflora were evaluated for aerobic microorganisms after defeathering, evisceration, washing, chilling, and sanitizing during a commercial chicken processing and storage at wholesale and retailsale levels. Sampling was at between December 1997, and March, 1998. Tap water washing and sanitizing with 25 ppm chlorine for 10 sec significantly (P$lt;0.05) reduced aerobic plate counts (APC) and gram-negative bacterial counts (GNC) on chicken carcasses from a commercial chicken-processing plant. After 4 days at 2±2℃, APC and GNC on chicken carcasses in retailsale store rapidly increased compared to those in wholesale store (P$lt;0.05). Chicken wings from retailsale store significantly (P$lt;0.05) decreased generation time (GT) compared to other chicken carcasses.
