Recently, food safety has become a great concern for consumers. In the United States, foodborne diseases have been estimated to cause 6 million to 81 million illnesses and up to 9,000 deaths each year. Annually, about 40,000 cases of non-typhoidal salmonellosis, primarily foodborne, are reported to the CDC. A better understanding of the colonization of Salmonella in broiler chicks via Alphitobius diaperinus (both adult and larval stages) is critical to designing prevention strategies. The importance of A. diaperinus as reservoirs for Salmonella typhimurium in broiler flocks will be determined by assessing Salmonella persistence in the adult and larval stages of A. diaperinus, as well as ability of S. typhimurium to spread in broiler flocks.
