Multidrug-resistant pathogens in the food supply

Area of Science:

• Microbiology
• Public Health
• Food Safety

Background:

• Antimicrobial resistance (AMR), particularly multidrug resistance (MDR), is a significant and escalating global health concern.
• MDR bacteria are prevalent in human and animal populations worldwide, leading to increased morbidity, mortality, and healthcare costs.

Purpose of the Study:

• To highlight the global increase in antimicrobial resistance (AMR) and multidrug resistance (MDR) in bacteria.
• To identify sources and transmission routes of MDR bacteria in the food chain.
• To emphasize the need for coordinated strategies to combat MDR in food.

Main Methods:

• Review of existing surveillance data and scientific literature on MDR bacteria in food.
• Identification of potential contamination points in the food supply chain, from farm to table.
• Analysis of factors contributing to the selection and spread of MDR bacteria.

Main Results:

• MDR bacteria are frequently detected in various food products, including meat and fresh produce.
• Foodborne pathogens like Salmonella, Campylobacter, and Shigella exhibit increasing MDR trends.
• Widespread antibiotic use in medicine and agriculture is a primary driver for the selection of MDR bacteria.

Conclusions:

• MDR bacteria pose a serious threat to human health through foodborne exposure.
• Contamination can occur through various routes, including contaminated water, food handlers, and agricultural practices.
• Enhanced surveillance and coordinated strategies for antimicrobial use in human and animal health, as well as agriculture, are crucial for mitigation.
