It's hard to go wrong with a legit oyster happy hour -- that is, unless it comes with a side of the stomach flu.
While there's always been the threat of slurping a bad raw oyster (here's how to avoid that), it turns out some of the normally delicious bivalves could also be carrying norovirus, aka the stomach flu, according to a new study published in Applied and Environmental Microbiology.
After analyzing the DNA of over 1,000 samples of norovirus from oysters, researchers found that 80% of known human norovirus strands matched the ones found in oysters, according to a report by TIME. This was especially the case when looking at oysters found in coastal regions that are more likely to be polluted by human sewage. Mmm, delicious.
