The biggest issue was inadequate control in the post-processing area where product is exposed. As a RTE product, Listeria, as well as allergens, are a significant risk. From the inspection notes, the company was not doing an very good job. FDA "found that eight (8) of eighty-five (85) swabs were positive for L. monocytogenes. Of the positive findings, one (1) swab was collected from an area adjacent to food-contact surface where RTE ingredients were being prepared on the filling table. This was not the first time L. monocytogenes was found in environmental samples collected at your facility. In 2017, FDA detected L. monocytogenes in one (1) environmental swab of a floor drain, and in 2018 FDA detected L. monocytogenes in eight (8) environmental swabs, including from areas adjacent to food-contact surfaces."
On further analysis, "Whole genome sequencing (WGS) was conducted on the above referenced L. monocytogenes isolates obtained from the FDA environmental samples. Based on the results of the WGS analysis, the seventeen (17) isolates comprise three (3) different strains of L. monocytogenes. Of particular significance, fourteen (14) isolates derived from the environmental samples collected at your facility during our 2021, 2018, and 2017 inspections were genetically identical, representing a single strain of L. monocytogenes. Additionally, these fourteen (14) isolates were also genetically identical to three (3) environmental swabs collected by Georgia Department of Agriculture (GDA) during a 2016 inspection of your facility. The presence of the same strain of L. monocytogenes over multiple years is indicative of a resident pathogen or harborage site in your facility since 2016. We advised you of the importance of these WGS results via a conference call on August 3, 2021."
