Handling of uncooked meat and consumption of undercooked meat are the primary sources of human Campylobacter infections. This pathogen primarily resides in the gastrointestinal tract of poultry and caused contamination of meat during poultry processing. jejuni outbreaks in 2018 were implicated to poultry and poultry products. About 90% of the campylobacteriosis is caused by C. In the United States alone, more than 1.3 million human campylobacteriosis cases are reported every year and leads to an economic burden of $1.9 billion ( Scallan et al., 2011 Batz et al., 2014 Marder et al., 2017). jejuni in poultry meat.Д¬ampylobacter jejuni and Campylobacter coli are foodborne pathogens that cause gastroenteritis (campylobacteriosis) in humans and affect around 95 million people annually worldwide ( Scallan et al., 2011 Kirk et al., 2015). This study supports that the application of phytochemicals in postharvest poultry would significantly reduce C. The cell viability test revealed that cells treated with 0.25% of phytochemicals had compromised cell membranes indicating this as a mechanism that phytochemicals use to damage/kill C. In addition, all the phytochemicals at SIC reduced quorum sensing of C. jejuni to chicken embryo cells ( p < 0.05). The selected phytochemicals (except curcumin) reduced the adhesion of C. jejuni counts were reduced by 1.0вЂ“1.5 Log CFU/sample with garlic oil or ginger oil at 0.25 and 0.5% ( p < 0.05). Data were analyzed by GraphPad Prism version 9. In addition, droplet digital PCR determined the gene expression analyses of C. The effects of phytochemicals on quorum sensing and cell viability were investigated using Vibrio harveyi bioluminescence and LIVE/Dead BacLight TM bacterial viability assays, respectively. jejuni and incubated in the presence or absence of phytochemicals for 1.5 h, followed by plating to enumerate adhered C.

Adhesion assay was conducted on the monolayers of ATCC CRL-1590 chicken embryo cells challenged with C.

The mechanisms of action(s) were investigated using subinhibitory concentration (SIC) in adhesion, quorum sensing, and gene expression analyses.

Skin samples were dipped into their respective prechilled treatment solutions (0.25 and 0.5% in experiments 1 and 2, respectively) at 4вЊ for an hour to simulate chilling tank treatment, followed by plating to enumerate C. jejuni strain S-8 and allowed to adhere for 30 min. Samples were inoculated with 50 Ојl (в€ј10 7 CFU/sample) of C. Two experiments were conducted on the thigh skin of the chicken, and each experiment was repeated twice. This study investigated the efficacy of phytochemicals, namely, turmeric, curcumin, allyl sulfide, garlic oil, and ginger oil, to reduce Campylobacter jejuni in postharvest poultry and sought to delineate the underlying mechanisms of action. Current strategies employed to reduce Campylobacter in live chickens provide inconsistent results indicating the need for an alternative approach.
