US Marshalls seized dairy products worth nearly $4 million from a Virginia dairy processing facility. Products were nonfat milk powder and buttermilk powder packaged in 40- and 50-pound bags for further manufacturing. This comes after regulators, conducted an investigation of the facility, "observed poor sanitary practices and reviewed the company’s records, which showed positive results for Salmonella in the plant’s internal environmental and finished product samples. FDA investigators observed residues on internal parts of the processing equipment after it had been cleaned by the company and water dripping from the ceiling onto food manufacturing equipment. In addition, environmental swabs collected during the inspection confirmed the presence of Salmonella meleagridis on surfaces food came into contact with after being pasteurized."
Through the use of whole genome sequencing on the Salmonella samples, it was determined that the strain found was persistant in that facility over time. "The sampling results indicate that the Salmonella strains from 2016 are nearly identical to Salmonella strains found at the company in 2010, 2011 and 2013. These findings of Salmonella meleagridis at the company dating back several years demonstrate the existence of a persistent strain of Salmonella at this facility."
No illnesses have been linked to the product to this point, but that may be due to a number of factors such as actual amount of organisms in product, the virulence of the organism, as well as the application of the milk powder and the type of processes used where this was an ingredient.
