Changes of the bacterial community diversity on chicken carcasses through an Australian poultry processing line.

In this study, 10 chicken carcasses were randomly sampled from before and after scalding, before and after immersion chilling, and after air chilling each through a modern commercial processing line, along with the contents of 10 caeca. The sampled processing line effectively reduced the bacterial counts by > 4.6 Log10 CFU/ml for each of Total Viable Counts, Escherichia coli and Campylobacter. However, the metagenomics results suggested that Lactobacillus, Staphylococcus and unclassified Lachnospiraceae persisted at all sampling stages. Pseudomonas, Paeniglutamicibacter, Chryseobacterium and Pseudarthrobacter comprised 47.2% in the bacterial community on samples after air chilling compared to 0.3% on samples after immersion chilling, whereas TVCs were the same. Overall, the current interventions of the investigated poultry processing line were unable to eliminate persistence of certain foodborne pathogens, despite a significant reduction of the overall bacterial counts. Chilling is an important controlling point in contamination/cross-contamination, particularly extended air chilling. Lastly, the large presence of Pseudomonas on chickens after air chilling may lead to downstream spoilage related issues, which needs more investigation to explore quantitatively the effect on the shelf life of poultry products.

In this study, we evaluated the efficacy of our two previously developed real time-quantitative PCR (qPCR) assays for the detection of swine-associated Bacteroidales genetic markers (gene 1–38, gene 3–53) in the Yangtze Delta watershed of southeastern China. The results indicated that the gene 1–38 and 3-53 markers exhibited high accuracy (92.5%, 91.7% conditional probability, respectively) in detecting Bacteroidales spp. in water samples. According to binary logistic regression (BLR), these two swine-associated markers were well correlated (P

This study aimed to assess the efficacy of four different sanitizers in reducing the microbial load from naturally contaminated chicken meat carcasses collected from the processing plants in South Australia. There was a significant variation in a load of Campylobacter and total viable count (TVC) between samples collected from two different processing plants and within carcass batches collected from the same plant that was tested during the study. All sanitizers generally reduced the load of Campylobacter on chicken meat carcasses. Treatment with acidified sodium chlorite significantly reduced the level of Salmonella enter...

(NEW YORK) — Go ahead and rinse your cranberries, potatoes and green beans. But food experts say don’t — repeat don’t — wash the turkey before popping it in the oven on Thanksgiving Day. They say that could spread the germs lurking on your turkey in the kitchen sink or nearby food. But it’s been a challenge trying to convince cooks to stop rinsing off raw poultry. “If your mother did it and your grandmother did it, and suddenly the (government) says not to wash your turkey, you may take some time to adjust,” said Drusilla Banks, who teaches food sanitation for the University ...

CONCLUSION: All the three methods have high accuracy for the diagnosis of H. pylori infection in the Vietnamese population with gastritis and gastric ulcers. These tests can be employed in the clinical settings for the Vietnamese population. CLO test should be used in combination with the other tests to reduce false-negative results.
