Approaches for reducing Salmonella in pork production

Area of Science:

• Food Safety
• Veterinary Public Health
• Microbiology

Background:

• Salmonellosis is a significant human disease linked to contaminated food, particularly pork.
• Salmonella persists latently in swine, posing a risk for carcass contamination despite abattoir controls.
• Swine management practices impact zoonotic enteric pathogen spread and food safety.

Purpose of the Study:

• To review pre- and post-harvest strategies for Salmonella control in pork production.
• To explore non-antibiotic approaches for enhancing swine gut flora and targeting intestinal pathogens.
• To emphasize integrated strategies across the pork supply chain, omitting subtherapeutic antibiotics.

Main Methods:

• Literature review of current and potential Salmonella control methods.
• Analysis of swine management practices influencing pathogen transmission.
• Examination of post-slaughter processing interventions.

Main Results:

• Preharvest enhancement of gut flora and non-antibiotic interventions show promise for food safety.
• Integrated approaches in swine operations and processing are crucial for Salmonella reduction.
• Multidrug-resistant pathogen threats necessitate revisiting traditional control methods.

Conclusions:

• A holistic strategy involving veterinarians, producers, and researchers is vital for Salmonella control.
• Reducing Salmonella contamination requires interventions throughout the pork production and processing chain.
• Omitting subtherapeutic antibiotics is essential for sustainable Salmonella management and combating antimicrobial resistance.
