“…In general, the occurrence of human campylobacter gastroenteritis has been largely attributed to the consumption of contaminated food animal products, especially poultry, because of the high prevalence of campylobacters in these animals (3,10,12,27,43). A growing body of evidence, however, suggests that other vehicles such as red meat, environmental water, and unpasteurized milk may be important sources of these organisms (19,25,44).…”

The prevalence of thermophilic Campylobacter spp. was investigated in cattle on Washington State farms. A total of 350 thermophilic Campylobacter isolates were isolated from 686 cattle sampled on 15 farms (eight dairies, two calf rearer farms, two feedlots, and three beef cow-calf ranches). Isolate species were identified with a combination of phenotypic tests, hipO colony blot hybridization, and multiplex lpxA PCR. Breakpoint resistance to four antimicrobials (ciprofloxacin, nalidixic acid, erythromycin, and doxycycline) was determined by agar dilution. Campylobacter jejuni was the most frequent species isolated (34.1%), followed by Campylobacter coli (7.7%) and other thermophilic campylobacters (1.5%). The most frequently detected resistance was to doxycycline (42.3% of 350 isolates). Isolates from calf rearer facilities were more frequently doxycycline resistant than isolates from other farm types. C. jejuni was most frequently susceptible to all four of the antimicrobial drugs studied (58.8% of 272 isolates). C. coli isolates were more frequently resistant than C. jejuni, including resistance to quinolone antimicrobials (89.3% of isolates obtained from calves on calf rearer farms) and to erythromycin (72.2% of isolates obtained from feedlot cattle). Multiple drug resistance was more frequent in C. coli (51.5%) than in C. jejuni (5.1%). The results of this study demonstrate that C. jejuni is widely distributed among Washington cattle farms, while C. coli is more narrowly distributed but significantly more resistant.

“…Casecontrol studies have identified a significant association between Campylobacter infection in humans and handling and consumption of poultry (3,10,12,27,43). However, other studies have reported an association with cattle (2, 8, 19, 28-30, 41, 53, 54, 59, 61).…”

“…Campylobacterjejuni contamination of commercially produced chickens has been widely reported (Smith & Muldoon, 1974;Simmons & Gibbs, 1979;Park et al 1981;Shanker et al 1982). Serotyping of human C. jejuni isolates has shown that many chicken and human strains are of the same serotype (Lior et al 1981;McMyne et al 1982;Munroe, Prescott & Penner, 1983;Abbott et al 1983).…”

SUMMARYThe role of broiler eggs in the transmission ofCampylobacter jejunito broiler grow-out flocks was investigated. Six breeder flocks supplying broiler eggs to hatcheries were examined for cloacal carriage ofC. jejuni. Of 240 birds tested, 178 (74%) wereC. jejuni-positive. Eggs from these birds examined forC. jejunipenetration of the egg shell indicated that 185 of 187 were campylobacter-free. Eggs from breeder flocks of unknownC. jejunistatus were also examined forC. jejunishell penetration.C. jejuniwas not isolated from 142 eggs examined. A further 193 hatchery eggs incubated and hatched in the laboratory were campylobacter-free. Six farms containing the progeny ofC. jejuni-positive breeder flocks were monitored. Eight hundred and forty birds from 14 flocks m these grow-out farms were campylobacter-free during their 6-week grow-out period. Experimental egg-penetration studies indicated thatC. jejunitransmission via the egg is not easily effected. Of 257 eggs surface-challenged withC. jejuni, 162 hatched; all were campylobacter-free. Of 167 eggs injected withC. jejuni, 12 hatched; 2 of these were colonized withC. jejuni. Our data do not support a role for vertical transmission ofC. jejuniin commercial broiler production.

“…Handling and consumption of poultry or poultry-related products are considered to be a primary source for Campylobacter-induced disease in humans (5,18,24). Campylobacter has been cultured from as many as 75% of the live broiler population and from as much as 80% of processed poultry meat samples sold commercially (13,14,19,27).…”

Campylobacter isolates from diverse samples within broiler production and processing environments were typed by using flaA short variable region DNA sequence analysis. Sixteen flocks from four different farms representing two broiler producers in Arkansas and California were analyzed. Fourteen of the flocks (87.5%) were Campylobacter-positive; two remained negative throughout the 6-week rearing period. In general, multiple clones were present within a flock. Additionally, clones found within a flock were also present on the final product, although the diversity of Campylobacter spp. on the final product appeared to be reduced relative to that observed within the flock. Comparison of clones between flocks on the same farm revealed that some clones of Campylobacter persisted in multiple flocks. Furthermore, some clones were identified across the two farms that were under the same management. In two sampling periods, environmental isolates were positive for Campylobacter prior to flock shedding. Environmental samples associated with five additional flocks were positive for Campylobacter concomitantly with recovery of Campylobacter from the birds. Analysis of the environmental isolates that were positive prior to flock shedding demonstrated that in some instances the environmental isolates possessed genotypes identical to those of isolates originating from the flock, while in other cases the environmental isolates possessed genotypes that were distantly related to isolates obtained from the flock. Analyses of environmental isolates that tested positive concurrently with the positive isolates from the flocks demonstrated varied results; in some instances the environmental isolates possessed genotypes identical to those of isolates originating from the flock, while in other cases the environmental isolates possessed genotypes that were distantly related to isolates obtained from the flock. These data suggest that the external environment may contribute to Campylobacter contamination during poultry production and processing. However, environmental contamination with Campylobacter does not appear to be the sole contributing factor.
