Pre-Harvest Non-Typhoidal Salmonella Control Strategies in Commercial Layer Chickens

Roshen N Neelawala et al. Animals (Basel). .

Abstract

Non-typhoidal Salmonella (NTS) infections in poultry, particularly in commercial-layer chickens, pose a critical risk to food safety and public health worldwide. NTS bacteria can remain undetected in poultry flocks, contaminating products and potentially leading to gastroenteritis in humans. This review examines pre-harvest control strategies for NTS in layer chickens, including biosecurity protocols, vaccinations, feed additives, genetic selection, and environmental management. These strategies have substantially reduced Salmonella colonization and product contamination rates in the commercial layer industry. By evaluating these strategies, this review highlights the importance of integrated control measures to limit NTS colonization, reduce antimicrobial resistance, and improve poultry health. This review aims to provide producers, researchers, and policymakers with insights into effective practices to minimize Salmonella contamination and enhance both animal and human health outcomes.

Keywords: antimicrobial resistance; biosecurity; feed additives; food safety; layer chickens; non-typhoidal Salmonella; poultry health; pre-harvest control; vaccination.
