Abstract

Effects of acetic or lactic acid and spray washing decontamination treatments, applied during processing of broiler chickens, in reducing the microbial load were investigated. Following scalding, chickens were either dipped in 0.5% acetic acid, 0.25% lactic acid or were spray washed with water alone or water with added 0.50% acetic acid or 0.25% lactic acid. Scalding (58C, 2 min) was achieved in water containing either acetic or lactic acid, or no acid at all; scald water was later collected for microbial analysis and the microbial counts were statistically analysed. Addition of acid to scald water lowered the microbial load, lessening the possibility of cross contamination of chicken internal organs and edible tissues. Dipping the defeathered and eviscerated birds in acid also lowered the microbial load, although this was not as effective as spray washing with an acid-water solution. Dipping or spraying the chickens in this way significantly improved their microbiological quality, and so enhanced their shelf-life.
