So it turns out that the flap a couple of months ago about the FDA banning cheese aged on wooden boards was not a fluke, but a sounder to see how the community at large would react.   They have now enacted rules that are threatening the importation of huge numbers of cheeses from across the globe.

The TL;DR version is that they have dropped the allowable amount of certain harmless bacteria from 100 per gram to 10 per gram.  They aren’t even trying to assert that the bacteria are harmful, but that they act as indicators of the cleanliness of the areas that they were prepared in.  There are no studies that show this to be the case.
