Spread of livestock-associated methicillin-resistant Staphylococcus aureus in poultry and its risks to public health: A comprehensive review.

The livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) strains are prevalent in the poultry farming environment and are a common component of the bacterial microbiota on the skin and mucous membranes of healthy animals. The origin and spread of LA-MRSA are attributed to the use of antibiotics in animals, and close contact between people and different animal species increases the risk of animal exposure to humans. The epidemiology of LA-MRSA in poultry significantly changed when ST398 and ST9 were found in food-producing animals. The significance of LA-MRSA and zoonotic risk associated with handling and processing foods of avian origin is highlighted by the LA-MRSA strain's ability to infect chickens. People who work with poultry are more prone to contract LA-MRSA than the general population. There is scientific consensus that individuals who have close contact with chickens can become colonized and subsequently infected with LA-MRSA; these individuals could include breeders, medical professionals, or personnel at chicken slaughterhouses. The prevention of LA-MRSA infections and diseases of poultry origin requires taking precautions against contamination across the entire chicken production chain.
