A recent study conducted by the American Society for Microbiology found that milk and beef may be responsible for the widespread infection of an antibiotic-resistant strain of staph bacteria known as MRSA. During the research, scientists discovered that the MRSA strain that has become increasingly common in humans for the last 15 years, was similar to the strain found in cows, which may indicate that the bacterial disease was caught from the animals. “Bovine strains … were closer to the root than the human strains” said Ross Fitzgerald of the Roslin Institute. “This led us to conclude that the strains infecting humans originated in cows and that they had evolved from bovine to human host jumps.”
