FDA Restrictions Keeping Some Great Cheeses Out of Stores

The limits for nontoxigenic E. coli were cut from 100 MPN (most probable number) per gram to 10 MPN. These are bacteria that live in every human gut; they are typically harmless and we coexist happily. But the FDA considers them a marker for sanitation: If a cheese shows even modest levels of nontoxigenic E. coli, the facility that produced it must be insufficiently clean.
