“…With this information, we hoped to determine whether variation in Campylobacter levels on the processed carcasses was related to the levels found on the broiler farm. Researchers have previously reported Campylobacter prevalence levels of 48, 94, and 98% for broiler carcasses (10,16,22). Smeltzer (16) also found carcasses to be contaminated with up to 5 log CFU of Campylobacter per carcass.…”

Twenty north Georgia commercial flocks of broiler chickens sampled in 1995 and 11 flocks sampled in 2001 were tested for Campylobacter spp. Direct plating on Campy-Cefex agar was carried out to determine levels of Campylobacter colonization within each flock through the enumeration of the organism in 50 fresh fecal samples 1 day prior to slaughter. The next morning, these flocks were the first to be processed, and levels of the organism per carcass before the chilling operation (50 carcasses per flock) in 2001 and after the chilling operation (50 carcasses per flock) in both 1995 and 2001 were estimated. Levels of the organism on freshly processed broiler carcasses were estimated by the same methods in 1995 and 2001, and a significant reduction from an average of 10(4.11) CFU per carcass in 1995 to an average of 10(3.05) CFU per carcass in 2001 was observed. Levels of Campylobacter spp. found in production and in processing were not strongly correlative, indicating the existence of complex parameters involving production factors and variables associated with flock transport and the processing of the broilers. The reduction in Campylobacter levels on processed carcasses may have contributed to the reduction in the frequency of human disease observed by the Centers for Disease Control during the same period. These data characterize the distribution of Campylobacter in north Georgia poultry operations and should assist in the development of risk assessment models for Campylobacter spp. The results obtained in this study suggest that the implementation of antimicrobial interventions by the poultry industry has already reduced consumer exposure to the organism.

“…It has been well established that chickens may carry C. jejuni in their intestinal tracts (4,19,26). The carcasses of chickens at retail are commonly contaminated with C. jejuni (17,23,27) and present a potentially important source of infection for humans. However, in our study it became clear that some flocks (19 of 26) were evidently free of the organisms, but other flocks (7 of 26) harbored the organisms and within the flock many birds were carriers.…”

“…Antisera were prepared at OVC in rabbits against 20 serotype reference strains of the scheme under development at the Department of Medical Microbiology at the University of Toronto (UOT) (17). Twenty strains (C. jejuni serotypes 1,2,3,4,5,8,10,11,16,18,19,21,23,31, 37, and C. coli serotypes 24, 28, 30, 34, and 38) were selected from the 59 defined serotypes because they were found in a previous prevalence study (17) to be the most frequently occurring. Previously described methods for antiserum production and titration by passive hemagglutination were followed (17).…”

A total of 191 Campylobacterjejuni and 125 Campylobacter coli were isolated from the intestinal content of 398 chickens, 421 cattle, and 203 pigs. All 108 chicken isolates and 73 of 80 cattle isolates were C. jejuni, but 115 of the 118 pig isolates were C. coli. A total of 84% of the C. jejuni and 64% of the C. coli isolates were typed on the basis of thermostable antigens with 20 antisera prepared against frequently occurring serotypes in Campylobacter enteritis in man (15 C. jejuni, 6 C. coli serotypes). A total of 96% of the chicken isolates and 67% of the cattle isolates belonged to 11 C. jejuni serotypes that occur most frequently in human cases of enteritis (serotypes 1, 2, 3, 4, 5, 13/16, 18, 21, 23, 31, and 36). Serotype 8, a relatively common human isolate, was not recovered. The C. coli isolates from pigs belonged to serotypes uncommon among human isolates.

“…Contamination with campylobacters during poultry processing has been extensively investigated (Smeltzer, 1981;Oosterom et al 1983 a) and the contamination of cattle, sheep and pig carcasses at slaughter has also been studied (Stern, 1981;Sticht-Groh, 1982;Oosterom et al 1983 …”

SUMMARYIn this study we examined 730 faecal samples of offal (mainly liver), mince-meat and sausage meat collected from abattoirs and retail butchers' shops for campylobacters.Campylobacter jejuniorC. coliwere isolated from 30·6, 10·5 and 6% of sheep, cattle and pig offal samples respectively. Specimens collected from abattoirs were, in general, more often contaminated than material obtained from retail butchers' shops. Only 1·4% of minced meats and sausage meats contained campylobacters. Most isolates (89·5%) wereC. jejunibiotype 1 (Skirrow & Benjamin, 1980) of serotypes 1 and 2 (Penner & Hennessy, 1980). This study shows that animal offal is frequently contaminated withC. jejuniof biotypes and scrotypes commonly isolated from human beings with campylobacter enteritis.
