“…Filth on the hock and brisket was found to be directly related to these areas having the highest levels of carcase contamination with TVC (McEvoy et al, 2000) and E. coli O157 . This is in agreement with Ridell and Korkeala (1993) who reported that briskets from excessively dungy cattle were significantly more contaminated than briskets from cattle which did not have large amounts of dung on the hide. Bell (1997) states that carcase Table 1 Shiga Toxin E. colielevels of contamination and contributing factors to pre-slaughter faeces and hide contamination.…”

“…Cattle hides have been identi ed as a source of general microbial contamination on carcasses (15,30,34,42), and it has been shown that E. coli O157:H7 can be transferred from hides to carcasses during processing (17). In the present study, E. coli O157:H7, Salmonella, and non-O157 STEC were found predominantly on hides, suggesting that hides are a more signi cant source of carcass contamination than feces.…”

The seasonal prevalence of Escherichia coli O157:H7, Salmonella, non-O157 E. coli (STEC), and stx-harboring cells was monitored at three Midwestern fed-beef processing plants. Overall, E. coli O157:H7 was recovered from 5.9% of fecal samples, 60.6% of hide samples, and 26.7% of carcasses sampled before the preevisceration wash. This pathogen also was recovered from 1.2% (15 of 1,232) of carcasses sampled at chilling (postintervention) at approximate levels of ,3.0 cells per 100 cm 2 . In one case, the E. coli O157:H7 concentration dropped from ca. 1,100 cells per 320 cm 2 at the preevisceration stage to a level that was undetectable on ca. 2,500 cm 2 at the postintervention stage. The prevalence of E. coli O157:H7 in feces peaked in the summer, whereas its prevalence on hide was high from the spring through the fall. Overall, Salmonella was recovered from 4.4, 71.0, and 12.7% of fecal, hide, and preevisceration carcass samples, respectively. Salmonella was recovered from one postintervention carcass (of 1,016 sampled). Salmonella prevalence peaked in feces in the summer and was highest on hide and preevisceration carcasses in the summer and the fall. Non-O157 STEC prevalence also appeared to vary by season, but the ef ciency in the recovery of isolates from stx-positive samples ranged from 37.5 to 83.8% and could have in uenced these results. Cells harboring stx genes were detected by PCR in 34.3, 92.0, 96.6, and 16.2% of fecal, hide, preevisceration carcass, and postintervention carcass samples, respectively. The approximate level of non-O157 STEC and stx-harboring cells on postintervention carcasses was $3.0 cells per 100 cm 2 for only 8 of 199 carcasses (4.0%). Overall, the prevalence of E. coli O157:H7, Salmonella, and non-O157 STEC varied by season, was higher on hides than in feces, and decreased dramatically, along with pathogen levels, during processing and during the application of antimicrobial interventions. These results demonstrate the effectiveness of the current interventions used by the industry and highlight the signi cance of hides as a major source of pathogens on beef carcasses.

“…A few reports have suggested that hides are a significant source of bacterial carcass contamination (6,10,34,44). Most reports have approached the problem by examining the potential for carcass contamination at critical processing steps by following changes in total aerobic, coliform, or generic E. coli counts or some combination of these (6,(17)(18)(19).…”

Escherichia coli O157:H7 and O157 nonmotile isolates (E. coli O157) previously were recovered from feces, hides, and carcasses at four large Midwestern beef processing plants (R. O. Elder, J. E. Keen, G. R. Siragusa, G. A. Barkocy-Gallagher, M. Koohmaraie, and W. W. Laegreid, Proc. Natl. Acad. Sci. USA 97:2999-3003, 2000). The study implied relationships between cattle infection and carcass contamination within single-source lots as well as between preevisceration and postprocessing carcass contamination, based on prevalence. These relationships now have been verified based on identification of isolates by genomic fingerprinting. E. coli O157 isolates from all positive samples were analyzed by pulsed-field gel electrophoresis of genomic DNA after digestion with XbaI. Seventy-seven individual subtypes (fingerprint patterns) grouping into 47 types were discerned among 343 isolates. Comparison of the fingerprint patterns revealed three clusters of isolates, two of which were closely related to each other. Remarkably, isolates carrying both Shiga toxin genes and nonmotile isolates largely fell into specific clusters. Within lots analyzed, 68.2% of the postharvest (carcass) isolates matched preharvest (animal) isolates. For individual carcasses, 65.3 and 66.7% of the isolates recovered postevisceration and in the cooler, respectively, matched those recovered preevisceration. Multiple isolates were analyzed from some carcass samples and were found to include strains with different genotypes. This study suggests that most E. coli O157 carcass contamination originates from animals within the same lot and not from cross-contamination between lots. In addition, the data demonstrate that most carcass contamination occurs very early during processing.
