Tom’s of Maine, the folksy, naturally sourced toothpaste of crunchy-granola-types everywhere, has a problem that, on the whole, seems to fit a brand preferred by dirty hippies. The Food and Drug Administration recently admonished the company after a government inspector found evidence of multiple bacteria in the company’s products and at one of its factories.

Dangerous bacteria linked to multiple infections found in final batches of Contaminated water used to make Tom’s of Maine toothpaste.

The company said it is working with the FDA to remedy issues found in the agency’s May inspection, including an upgrade to its Sanford plant’s water system.
