“…It is also possible that farms supplying poultry to supermarkets may have better biosecurity controls, and therefore lower Campylobacter prevalence in their broiler poultry, than those supplying wet markets: Campylobacter prevalence in flocks is significantly associated with factors such as distance between broiler farms, number of on-farm broiler houses, presence of other livestock on farm, etc. (Ansari-Lari, Hosseinzadeh, Shekarforoush, Abdollahi, & Berizi, 2011;Hansson, Engvall, Vågsholm, & Nyman, 2010).…”

“…This finding was in agreement with the results of Chadfield et al (12), and Gutierrez et al (22) who reported 25% in Denmark and 27% in Ireland, respectively. Ansari-Lari et al (23) reported that 22.5% of the broiler flocks of Shiraz were positive for Salmonella spp. The difference observed between the results of the current study and those of the latter study may be due to different detecting procedures; they used culture methods.…”

Background: Prevention of foodborne pathogens is essential to control infectious diseases; Salmonella spp. is referred to as the most common causative agent of foodborne illnesses. Objectives: The current study aimed to determine the prevalence of Salmonella enterica subsp. enterica in broiler flocks in Mazandaran province, north of Iran and find the potential risk factors including: age, size of flock, strain, season, vaccination program and use of antibiotics. Materials and Methods: From March 2012 to December 2013, a total of 50 flocks were selected in slaughterhouse and 20 cloacal samples were collected from each flock. Every five samples were pooled and investigated for Salmonella spp. using polymerase chain reaction (PCR). Results: Thirteen flocks out of 50 (26%) were positive for Salmonella species. Chances of Salmonella spp. detection was higher in flocks with lower age (P = 0.41). Increasing flock population was associated with increased chance of Salmonella spp. isolation (P = 0.21). The risk of salmonellosis in broiler flocks was increased when no antibiotics were given to day-old chicks. There was no significant difference (P = 0.30) in the prevalence of salmonellosis among different broiler strains. Conclusions: In the current study, six risk factors were assessed for Salmonella spp. contamination in broiler flocks. Some of these factors contributed to the risk of salmonellosis in broiler flocks.

“…Previous epidemiological studies identified potential risk factors associated with Campylobacter colonisation of flocks. These main factors are: the season (summer and/or autumn) (Huneau-Salaün et al, 2007;Ellis-Iversen et al, 2009), several poultry houses or presence of other animals in the same farm (Refregier-Petton et al, 2001;Ellis-Iversen et al, 2009), drinking water quality (Ellis-Iversen et al, 2009), administration of antibiotics (RefregierPetton et al, 2001;Ansari-Lari et al, 2011) and the lack of hygienic barriers (Evans and Sayers, 2000;Huneau-Salaün et al, 2007). In order to prevent the risk of human infection, another preventive measure, which has been poorly studied to date, could be to reduce the Campylobacter concentration at the farm level.…”

“…Previous studies on the prevalence and risk factors for Campylobacter spp. caecal colonisation in poultry at the slaughterhouse level (Hue et al, 2010;Ansari-Lari et al, 2011) showed that crosscontamination during slaughter and processing is difficult to control.…”

1. A study was conducted to estimate the prevalence and quantification by species of Campylobacter infection in broiler flocks at the end of the rearing period and to identify associated risk factors. 2. A questionnaire about the rearing period was completed and caecal samples were collected from 121 broiler flocks in Brittany, France, during 2008. 3. Campylobacter was isolated in 87 out of 121 flocks--a prevalence of 71.9% (95% CI, 63.7-80.1%), including 40.5% of Campylobacter jejuni and 29.8% of Campylobacter coli. 4. The average concentration, in positive flocks, was 7.96 log10 cfu/g and ranged from 3.15 to 10.32 log10 cfu/g. 5. The average concentration by species was: 7.57 log10 cfu/g for C. jejuni and 8.44 log10 cfu/g for C. coli. 6. There was a seasonal effect, with increased risk of Campylobacter colonisation in June, July and August (odds ratio (OR) = 9.59, 95% CI 1.15-79.75). 7. The other factors, associated with lower risk of Campylobacter colonisation, were the acidification of drinking water (OR = 0.33, 95% CI 0.13-0.86), antibiotic treatment at the beginning of the rearing period (OR = 0.20, 95% CI 0.07-0.55) and rodent control around the house (OR = 0.18, 95% CI 0.03-0.95). 8. The results show that hygiene practices and biosecurity measures could lead to a reduction in Campylobacter colonisation.
