“…Two more recent surveys in seven member-states of the European Communities yielded the following mean bacterial counts on freshly slaughtered beef carcasses: -Survey I: 3-85, 2-77, 2-29, 3-14, 2-45, 2-75 and 3-23; Survey II: 3-78, 3-15, 2-35, 3 50, 2-48, 3-11 and 3-33 (Roberts et al 1984). Nottingham, Penny & Harrison (1974) found little difference between the rail (vertical) and cradle (horizontal) flaying systems in the production of beef carcasses of high microbiological quality, but found that much of the contamination occurred during flaying as a high proportion of the isolates appeared to be of soil origin.…”

SUMMARYThe bacterial status of beef carcasses at a commercial abattoir was monitored before and after slaughterline automation. Bacterial counts did not differ significantly overall (P > 0 05) between the original manual line and the automated line for either morning or afternoon slaughter. On the manual line counts in the morning were lower than those from carcasses slaughtered in the afternoon, but on the automated line there was no difference between morning and afternoon counts. Due to highly significant line x sample site interaction for both morning and afternoon counts, overall differences among sample sites were not found by analysis of variance. However, principal components analysis revealed a significant shift in bacterial contamination among some sites due to slaughterline changes. The incidence of Enterobacteriaceae increased marginally following automation.

Bacteriological status of beef carcasses at a commercial abattoir before and after slaughterline improvements

SUMMARYThe bacteriological status of beef carcasses was monitored at a commercial abattoir before and after two stages of modernization to the beef slaughterline which included changing from cradle dressing to dressing on an overhead rail, and the introduction of hot water spray cleaning of carcasses. Although small significant (P < 0·05) differences in bacterial count occurred among carcass sites within modernization stages, significant visit within stage variation and stage × site interactions prevented any significant change in overall count being observed among stages and carcass sites. Principal components analysis revealed small changes in the distribution of bacterial numbers on the sites sampled.

Six bacterial sampling methods that might be used for rapid sampling of beef carcasses were evaluated in two separate studies. In Study 1, bacterial recovery from uninoculated beef rounds was 2.6, 2.3, 2.1 and 1.3 log,,, cfu cm-2, respectively for excision (EX), and swabbing with cheesecloth (CC), sponge (SP) and cotton-tipped wooden swabs (CS). For Study 2, beef tissue was inoculated with bovine faeces at different levels and the mean recovery was 3.7, 3.0, 3.1 and 3.1 log,, cfu cmp2, respectively for EX, and swabbing with SP, griddle screen (GS) and 3M mesh (M). For both studies EX was determined to be the most consistently effective method while the initial study determined swabbing with CS was the least effective of the methods used. In both studies the most abrasive materials approached the effectiveness of EX even at low inoculation levels. As the inoculation levels increased, the additional effect of abrasiveness was lessened. When the carcasses were contaminated with bovine faeces, the bacterial populations that were rapidly recoverable from beef tissue using SP, GS or M were not significantly lower than those recovered using EX. Consequently SP, GS or M are an adequate method of beef carcass sampling for rapid, in-plant process monitoring to detect faecal contamination.
