Bacterial infections in pigs and pig farmers caused by MRSA (Methicillin-resistant Staphylococcus aureus)

In the world of livestock, a particular strain of bacteria known as MRSA ST398 has been causing concern. This strain, which is notably prevalent in pigs and other livestock, has been linked to a higher likelihood of close contact with these animals. Despite human cases of ST398 being extremely rare in Canada, experts warn that this could change as the strain spreads among the pig population.

MRSA ST398, or non-typeable MRSA (NT-MRSA), is a dominant livestock-associated MRSA (LA-MRSA) strain that often colonizes pigs. A recent global study reported an overall prevalence of Staphylococcus aureus in pigs around 6.94%, with a higher prevalence in cattle and buffaloes. ST398 is recognized as a common colonizer of farm animals, especially pigs.

Humans in frequent contact with pigs and other livestock, such as farmers or veterinarians, are more commonly colonized with MRSA ST398. Transmission is thought to occur through direct animal contact and inhalation of contaminated dust. Despite frequent colonization among exposed individuals, clinical infections caused by MRSA ST398 in humans remain rare.

The food chain is not entirely safe, and the risks could be higher for people who handle meat directly or those with weakened immune systems. The bacteria could potentially spread to friends and family of pig farmers by hitching a ride on clothes or skin. At least one hospital outbreak began when an immunocompromised patient ate contaminated meat, setting a dangerous precedent.

Tara Smith, a researcher from the University of Iowa, led a study that found widespread traces of MRSA in pig farms in the states of Iowa and Illinois. Unnecessary antibiotic use in the farming industry has been blamed for the evolution of MRSA strains. Under such heavy antibiotic use, it is almost inevitable that bacteria, which reproduce quickly and swap beneficial mutations, will develop resistance.

The strain of MRSA found in Iowa and Illinois is the same as the one discovered in the Netherlands. Scott Weese from the University of Guelph in Ontario found the Dutch strain of ST398 in a quarter of local pigs and more worryingly, in a fifth of pig farmers. Van Loo detected ST398 in 2 out of 79 meat samples from Dutch supermarkets and butchers, but at low levels unlikely to cause disease if food is properly prepared.

Control measures should be implemented to protect farmers and the wider population once the extent and causes of the MRSA epidemic are better understood. More research and better monitoring are needed to fully understand the scale of the MRSA epidemic in pigs and the role that agricultural antibiotics have played in it. The spread of MRSA ST398 is considered a public and veterinary health concern due to its zoonotic potential (animal to human transmission) and the risk of antibiotic resistance spread. Surveillance and farm hygiene improvement are recommended to reduce animal colonization and subsequent human exposure.

Despite being non-existent in 2002, ST398 now accounts for over one in five human infections. Continued monitoring and preventive measures on farms are crucial to mitigate potential future risks. It's important to note that this news article provides factual information and does not aim to create alarm or fear. Rather, it aims to inform the public about the potential risks associated with MRSA ST398 and the importance of continued monitoring and preventive measures.
