The US Food and Drug Administration (FDA) found “serious” food safety violations at a seafood processing facility operated by Massachusetts-based M&B Sea Products, the FDA said in a warning letter to the company.

Refrigerated, reduced-oxygen packaged raw scallops at the facility have been “prepared, packed or held under insanitary conditions whereby they may have been rendered injurious to health,” the FDA said in the Aug. 26 letter.

John Murray, president of the New Bedford-based company, did not respond to requests for comment from Undercurrent News on Tuesday. Mutahar Shamsi, director of the FDA’s New England district, declined to comment on an open case.
