Abstract

Abstract: The microbial contamination of animal carcasses with respect to the limits established by Regulation (EC) No. 2073/2005 was investigated. Bovine, ovine, and swine carcasses (n = 536 samples) from three small-scale abattoirs were sampled using abrasive sponges and tested for aerobic colony counts (ACC) and Enterobacteriaceae in the period 2010–2013. Mean ACC values reached 1.96 log cfu/cm 2 on bovine carcasses and 2.27 log cfu/cm 2 on both swine and ovine carcasses; Enterobacteriaceae counts of 0.01, 0.20 and 0.27 log cfu/cm 2 were found for bovine, swine and ovine carcasses, respectively. Abattoir 1 showed the highest values of ACC; no differences among abattoirs were highlighted for Enterobacteriaceae . Compared with swine and ovine carcasses, bovine carcasses showed significantly lower means for both ACC and Enterobacteriaceae . The data collected indicated that the management of the three abattoirs met high quality standards, thereby proving that it is feasible to achieve good microbiological quality in abattoirs when adequate Good Hygiene Practices are applied. Highlights: The hygiene process of 3 small-scale abattoirs was assessed. Low frequencies of microbiological unacceptable values were recorded. Bovine carcasses showed the lowest ACC and Enterobacteriaceae daily means. The management of the three abattoirs achieved high quality standards. No seasonal trend was observed in any particular abattoir or species sampled.
