Greg Frank, director of Working to Fight AMR, a group that fights drug resistant infections, told USA TODAY the report underscores the importance of antibiotic-resistant infections as a problem.

“Drug-resistant superbugs are now evolving much faster than we are inventing new antibiotics and other treatments to fight back against them,” said Frank.

This strain in question, found only in beef and soft cheese, was linked to dairy cows. That’s also worrisome, Plumb said, since the findings suggest that the strain could be spread in cattle. 

“We know that any use of antibiotics, in people, animals, and the environment, can lead to the development and spread of resistant bacteria,” said Plumb.
