ABSTRACT In this study, Karmali agar was modified by adding tazobactam (T-Karmali agar) to suppress the growth of extended-spectrum β-lactamase (ESBL)–producing Escherichia coli, which frequently contaminates raw poultry meat. By inoculating 30 Campylobacter spp. strains and 25 ESBL-producing E. coli strains onto Karmali agar and T-Karmali agar containing various concentrations of the antibacterial agent, we determined the optimum concentration of tazobactam to be 4 mg/liter. The Campylobacter spp. isolation rate on T-Karmali agar (13.3%) was higher than that on Karmali agar (8.3%), although the difference was not significant (P > 0.05). However, T-Karmali agar showed a significantly greater selectivity than Karmali agar, as evaluated by comparing the numbers of contaminated agar plates (20.8 versus 82.5%; P < 0.05) and the growth indexes (1.36 versus 2.83) of competing flora. The predominant competing flora on Karmali and T-Karmali agar were identified as ESBL-producing E. coli. Thus, T-Karmali agar might be effective for determining the real prevalence of Campylobacter in raw poultry and, especially, contamination with ESBL-producing E. coli.

Campylobacter Spp

Background: F Campylobacter species are imperative foodborne bacteria because of the contaminated poultry meat consumption. Objectives: This study was conducted to recognize the incidence and antimicrobial resistance profile of Campylobacter species recovered from raw poultry meat samples. Materials and Methods: A total of 695 poultry meat samples were collected and assessed by culture technique. Bacterial species were identified by polymerase chain reaction (PCR). Antimicrobial resistance was assessed by disk diffusion method (DDM). Results: The contamination rate of samples with Campylobacter spp. was 44.75% with higher contamination rate of wild duck (84%), wild goose (83.33%), coot (78.26%), chicken (67.78%), and wild pheasant (66.66%), respectively. Campylobacter jejuni and C. coli bacteria were found in 84.24% and 15.76% of Campylobacter spp., respectively. The highest incidence of C. jejuni was obtained in partridge (95.45%), quail (95%), pheasant (92.31%), and wild duck (90.48%) meat samples, respectively. The highest incidence of C. coli was found in turkey (52.63%) and wild pheasant (22.22%) meat samples, respectively. Moreover, C. jejuni had the highest resistance to tetracycline (76.34%), nalidixic acid (65.65%), ciprofloxacin (58.78%), enrofloxacin (39.69%), and ampicillin (38.55%), respectively. C. coli had the highest resistance to nalidixic acid (48.99%), ciprofloxacin (40.82%), and enrofloxacin (38.78%), respectively. Conclusion: Poultry meat, particularly partridge, quail, pheasant, turkey, and wild avian are the main sources of Campylobacter transmission. Furthermore, higher incidence and antibiotic resistance of C. jejuni was found. Proper cooking of poultry meat and monitoring the antibiotic prescription can lessen the occurrence of antibiotic-resistant Campylobacter spp. in poultry meat.

The objectives of this study were to quantify Salmonella counts on retail raw poultry meat in Vietnam and to phenotypically characterize (serovars and antibiotic resistance) the isolates. A total of 300 chicken carcasses were collected from two cities and two provinces in Vietnam. Salmonella counts on the samples were determined according to the most-probable-number (MPN) method of the U.S. Department of Agriculture, Food Safety and Inspection Service (USDA-FSIS). A total of 457 isolates were serotyped and tested for antibiotic susceptibility. Overall, 48.7% of chicken samples were Salmonella positive with a count of 2.0 log MPN per carcass. There were no significant differences (P > 0.05) in log MPN per carcass by the study variables (market type, storage condition, and chicken production system). There was a significant difference (P < 0.05) in Salmonella-positive prevalence by chicken production system. Among the 22 Salmonella serovars identified, Albany was the most frequent (34.1%), followed by Agona (15.5%) and Dabou (8.8%). Resistance to at least one antibiotic was common (i.e., 73.3%), with high resistance to tetracycline (59.1%) and ampicillin (41.6%). Resistance to three antibiotics was the most frequently found multidrug resistance profile (17.7%, n = 81); the profile that was resistant to the highest number of drugs was resistant to nine antibiotics (0.7%, n = 3). Only Salmonella Albany posed phenotypic resistance to ceftriaxone (a drug of choice to treat severe cases of salmonellosis). The data revealed that, whereas Salmonella prevalence on raw poultry was high (48.7%), counts were low, which suggests that the exposure risk to Salmonella is low. However, improper storage of raw chicken meat and cross-contamination may increase Salmonella cell counts and pose a greater risk for infection. These data may be helpful in developing risk assessment models and preventing the transmission of foodborne Salmonella from poultry to humans in Vietnam.

Campylobacter Spp

An observational study was conducted to estimate prevalence and risk factors for carcass contamination by Salmonella and Campylobacter spp. in 60 lots of turkey slaughtered over 10 months in the province of Quebec, Canada. Carcass contamination was evaluated by the carcass rinse technique for about 30 birds per lot. Exposure to potential risk factors was evaluated with questionnaires, meteorological data, and cecal cultures. Multivariable binomial negative regression models were used for risk factor analysis. Prevalence of Salmonella-positive carcasses was 31.2% (95% confidence interval, 22.8 to 39.5%). Variables positively associated (P ≤ 0.05) with the proportion of lot-positive carcasses were ≥0.5% of carcass condemnation due to various pathologies, cecal samples positive for Salmonella, low wind speed during transportation, closure of lateral curtains of truck during transportation, and slaughtering on a weekday other than Monday. When only Salmonella-positive cecal culture lots were considered, the proportion of carcasses positive for Salmonella was significantly higher in lots exposed to a >5°C outside temperature variation during transportation, slaughtered on a weekday other than Monday, and in which ≥4% of carcasses had visible contamination. Prevalence of Campylobacter-positive carcasses was 36.9% (95% confidence interval, 27.6 to 46.3%). The proportion of positive carcasses was significantly higher in lots with Campylobacter-positive cecal cultures and lots undergoing ≥2 h of transit to slaughterhouse. For lots with Campylobacter-positive cecal cultures, variables significantly associated with an increased incidence of carcass contamination were ≥4% of carcasses with visible contamination, crating for ≥8 h before slaughtering, and no antimicrobials used during rearing.
