A study just released in PLoS One provides new evidence of the potential risk posed by livestock-associated, drug-resistant Staphylococcus aureus to hog workers and their families. The study, led by a team of investigators from the Johns Hopkins University Bloomberg School of Public Health, builds on their previous research into the emergence of livestock-associated S aureus in hog workers, which is believed to be linked to the widespread use of antibiotics in hog production. Their previous study found that employees of industrial hog farms, and their family members, may be more vulnerable to nasal carriage of S aureus, methicillin-resistant S aureus (MRSA), and multidrug-resistant S aureus (MDRSA). They were unable to determine from that research whether carrying drug-resistant S aureus in nasal passages actually represented a risk for infection. That’s what they wanted to determine in the current study. READ MORE
