“…Using such an approach, colonized flocks would be identified by farm sampling and scheduled for slaughter at the end of the processing shift. A modeling study by Evers indicated that such an approach was likely to yield little benefit for Salmonella (37), however, and a study of 62 Dutch broiler flocks by Nauta et al found it impractical as a control strategy for Campylobacter (38). Logistic slaughter was not evaluated in the current study; all of the flocks enrolled were processed immediately after a sanitation shift.…”

A prospective cohort study was performed to evaluate the prevalences and loads of Salmonella and Campylobacter spp. in farm and processing plant samples collected from 55 commercial broiler chicken flocks. Environmental samples were collected from broiler houses within 48 h before slaughter, and carcass rinses were performed on birds from the same flocks at 4 different stages of processing. Salmonella was detected in farm samples of 50 (90.9%) flocks and in processing samples of 52 (94.5%) flocks. Campylobacter was detected in farm samples of 35 (63.6%) flocks and in processing samples of 48 (87.3%) flocks. There was a significant positive relationship between environmental farm samples and processing plant carcass rinses with respect to both Salmonella and Campylobacter prevalences and loads. Campylobacter loads were significantly higher than Salmonella loads, and the correlations between samples collected from the same flocks were higher for Campylobacter than they were for Salmonella. Boot socks were the most sensitive sample type for detection of Salmonella on the farm, whereas litter samples had the strongest association with Salmonella loads in pre-and postchill carcass rinses. Boot socks, drag swabs, and fecal samples all had similar sensitivities for detecting Campylobacter on the farm, and all were more strongly associated with Campylobacter loads in carcass rinses than were litter samples. Farm samples explained a greater proportion of the variability in carcass rinse prevalences and loads for Campylobacter than they did for Salmonella. Salmonella and Campylobacter prevalences and loads both decreased significantly as birds progressed through the processing plant.

“…Once negative flocks are identified in the field, it is necessary to ensure that broilers will not be contaminated during transportation from the farms to the slaughterhouse (Hansson et al 2005). However, a study conducted in the Netherlands by Nauta et al (2009) assessed 62 broiler flocks and did not find significant support for the implementation of control strategies targeted at the identification of positive flocks in the field and at slaughtering time. The correlation between the contamination of feces and of breast cuts by Campylobacter suggests these assessed criteria are not good indicative signs of human exposure to Campylobacter.…”

Occurrence of Campylobacter jejuni and C. coli on broiler carcasses after chilling in southern Brazil

Campylobacter jejuniand C. colihave been associated with gastrointestinal disorders in human beings, due mainly to the consumption of chicken meat. Despite control measures for reducing contamination by these bacteria, the detection of Campylobacter in carcasses after chilling remains high.A total of 105 carcasses were assessed by the horizontal detection method in five federally inspected slaughterhouses in southern Brazil in 2012 and in the first three months of 2013. Campylobacterwas isolated in 37.1% of the carcasses, of which 97.5% contained C. jejuni and 2.5% were infected by C. coli. The rate of positive carcasses across the slaughterhouses ranged from 0 to 71.4%. Determining the occurrence of Campylobacteramong flocks is crucial for estimating the microbial load at specific points along the slaughtering process and for minimizing the risk of contamination of end products by Campylobacter.

“…in those samples, possibly because contamination was low and it required enrichment (Table 3). Gharst et al (2006), Nauta et al (2009), andHabib et al (2011) obtained higher detection of Campylobacter spp. by the enrichment method and concluded that the number of Campylobacter spp.…”

“…after enrichment in Campylobacter Enrichment Broth (CEB) and suggested that a better recovery could have been obtained if the Preston broth, previously used by Bolton and Robertson (1982), had been used. However, an even better recovery could have been obtained by modifying the proportion between rinse and enrichment broth, e.g., 1:10had been already used by Kuana et al (2008) and Nauta et al (2009), instead of 1:4, used by Kiess et al (2010).…”

In 2006, the International Organization for Standardization (ISO) published two standard protocols for the detection and enumeration of Campylobacter spp. in foods: the ISO 10272-2(direct method) and the ISO 10272-1 (enrichment method). The aim of this study was to compare the efficiency of these two methods in the detection of Campylobacter spp. and propose a modification in the enrichment method. Compared with the enrichment method, the direct method yielded a higher number of positive results for Campylobacter spp. and, consequently, presented higher sensitivity percentage. The isolation of Campylobacter spp. was more difficult when 10 mL of rinse was used in the enrichment method, which is currently recommended by the ISO protocol. Therefore, different rinse volumes were tested (2.5 and 5 mL). The most efficient recovery of Campylobacter spp. occurred when 2.5 mL of rinse were used in the enrichment method, most likely due to a lower number of microbial contaminants than that present in the 5 or 10 mL rinses. The proposed modification of the enrichment method will contribute to the food analysis by improving the detection of Campylobacter spp. in chicken carcass.
