Evaluating the impact of livestock antibiotics on the environment, University of Minnesota researchers have found that many vegetables uptake the antibiotics. The study, in the Journal of Environmental Quality, shows that food crops can readily accumulate antibiotics from soils spread with cattle manure.
The findings were based on a greenhouse study involving three food crops: corn, lettuce, and potatoes. The plants were grown in soil modified with liquid hog manure containing sulfamethazine, a commonly used veterinary antibiotic. The researchers found that the antibiotic was taken up by all three crops.
