Contamination and bacterial retention capacity of beef carcasses at the abattoir

K riaa , H., A rthaud , J.F. & F ournaud , J. 1985 Contamination and bacterial retention capacity of beef carcasses at the abattoir. Journal of Applied Bacteriology 59 , 23–28. The contamination of beef carcasses was studied together with the capacity of meat surfaces to retain bacteria along the processing line in the slaughter hall.The results showed that the contamination varied along the processing line, but that this pattern was essentially dependent on the contamination at the dressing station. It decreased or remained unchanged during the first 12 min and then increased, even without additional contamination. The contamination varied according to carcasses and micro‐organisms studied and was not greatly affected by spray cleaning. The number of bacteria retained changed at a rate similar to that of the contaminants. The attachment was instantaneous. The results are discussed and compared with the various hypotheses about contamination and bacterial attachment processes.
