Historical changes in pig farming led to the global spread of Salmonella, resistant to antibiotics—a new international study led by researchers at the University of Warwick suggests.
Salmonella enterica is a type of bacteria responsible for millions of illnesses annually, that can contaminate food, water, and food processing facilities. It can enter the food supply chain, with pork being a major source of infections. The pathogen can "jump" from pigs to humans, causing severe, potentially fatal, illnesses.
Until now, the impact of intensive farming practices and global trade on Salmonella prevalence around the world and the spread of antibiotic resistance remained unclear.
