There is a new poultry safety strategy: postbiotics (compounds derived from probiotic bacteria) to reduce Salmonella contamination during processing. This approach is promising because postbiotics are stable, water-soluble, and can be easily integrated into existing chilling steps at processing plants1.
Salmonella remains one of the most significant foodborne pathogens in poultry, causing widespread recalls and serious health risks. Traditional washing and chilling steps often fail to eliminate contamination because bacteria survive in skin folds and feather follicles. Researchers at the University of Connecticut have developed a new strategy using postbiotic compounds to enhance food safety interventions.
Probiotics have been studied for their benefits in poultry production, including healthier birds, reduced feed consumption, and improved yields. However, the metabolites produced by these beneficial bacteria—known as postbiotics—offer additional advantages. Unlike probiotics, postbiotics are not living organisms, meaning they are unaffected by temperature and remain shelf-stable. They include antimicrobial molecules that can directly inhibit pathogens like Salmonella2.
One of the most practical aspects of this strategy is its compatibility with existing poultry processing steps. Postbiotics are soluble in water, making them easy to incorporate into the chilling tanks used after slaughter. By adding postbiotics during carcass chilling, processors can simultaneously maintain meat quality and reduce bacterial growth. This dual benefit supports both food safety and production efficiency.
Beyond safety, this approach offers economic advantages. Since postbiotics can be integrated without special formulations, they reduce costs associated with new equipment or complex handling. Additionally, producers benefit from healthier flocks due to probiotic supplementation, which lowers feed costs and increases productivity. This makes the strategy appealing not only for food safety but also for overall industry sustainability.
Initial trials focused on chicken skin inoculated with Salmonella, demonstrating that postbiotics can effectively reduce contamination. Researchers emphasize that this is a scalable solution, potentially applicable across different stages of poultry processing. Future studies aim to refine dosage levels and evaluate long-term impacts on consumer safety and industry economics.
Postbiotics represents a novel, science-backed strategy to improve poultry processing safety. By combining the benefits of probiotics with the stability of postbiotic compounds, this approach addresses persistent Salmonella risks while enhancing production efficiency. If widely adopted, it could significantly reduce foodborne illness outbreaks and strengthen consumer confidence in poultry products.
