Cow manure is commonly used to fertilize vegetable crops, and a US study out Tuesday found it contains a high number of genes that can fuel resistance to antibiotics.
These genes come from the cows' gut bacteria, and while none have yet been found in superbugs that are infecting humans, researchers said the potential is real.
The research was done by scientists at Yale University, who sampled manure from a handful of dairy cows at a farm in Connecticut.
In those samples, they found 80 unique antibiotic resistance genes.
