Basically, one shipment was found positive for a specific Salmonella strain. That shipment was destroyed. A few months later, the specific Salmonella strain was involved in cases of Salmonella. It was found that these people had eaten shrimp from a common shipment from the same company. The company has conducted a recall for product.
[TIP - Buy fresh frozen (not thawed) and cook it yourself, unless you can buy fresh, just caught]"On January 26, 2021, an import sample of Avanti Frozen Foods shrimp was collected as a routine part of the FDA’s Imported Seafood Compliance Program. Analysis of the sample showed the presence of Salmonella Weltevreden. At the time, there were no known associated illnesses or closely related isolates of this strain. In March 2021, as a result of the positive test, this shipment was refused admission into the U.S. and was destroyed, and the importing firm was added to Import Alert 16-81, which allows the FDA to detain product without physical examination due to the presence of Salmonella."In April 2021, three clinical isolates collected from ill people were reported to be closely related to the isolates collected from the import sample. As of June 25, 2021, there are now 6 clinical isolates from ill people that are genetic matches to the Salmonella collected from the import sample. Five of the six ill people were interviewed to determine the foods they ate before becoming sick, and all five ill people report eating shrimp. Based on purchase locations and purchase dates available for four ill people, FDA’s traceback investigation identified a common shipment of shrimp that could have been consumed by ill people. The product from this shipment was all sold thawed at retail. This thawed product is past expiration and no longer available for sale.
