Recalled yogurt contained highly pathogenic mold
Date:7/8/2014

ce, the results were less dramatic, resulting in severe weight loss in only one case.

The Duke researchers found that the fungus can survive passage through the gastrointestinal tract of the mice, suggesting it could opportunistically colonize an immune-compromised host.

"We still don't know if the fungus is infecting the gastrointestinal tract, or if it is producing some sort of toxin that makes people sick," said Heitman.

The researchers sequenced the entire genome of the fungus to look for clusters of genes that could produce toxic molecules called secondary metabolites. Although they uncovered a number of candidates, it is still unclear whether the fungus is making any toxins that could explain the symptoms experienced by people who ate the contaminated yogurt.

Heitman's laboratory also tested 16 other samples of Chobani yogurt and did not find Mucor circinelloides in any of them. The researchers asked the FDA for more information on its analyses of the recalled product or access to the samples the agency had obtained, and the agency declined their requests.
