Bacterial pathogens and indicators in refrigerated fresh herb paste - April 1, 2021, to March 31, 2024

Abstract

A targeted survey analyzed 147 samples of refrigerated fresh herb paste over a 3-year period from April 1, 2021, to March 31, 2024, for the presence of the pathogens Listeria monocytogenes, Salmonella spp., and E. coli O157. All samples were also tested for generic E. coli which is used as an indicator of the overall hygienic and sanitary conditions of the food supply chain from production to the point of sale. All (100%) of the 147 samples tested were found to be satisfactory. L. monocytogenes, Salmonella spp., and E. coli O157 were not found in any of the samples. Generic E. coli at elevated levels were not found in any of the samples. Overall, our survey results indicate that refrigerated fresh herb pastes sold in Canada are generally safe for consumption. However, as with all foods, and especially those that are ready-to-eat, good hygienic practices are recommended for producers, retailers, and consumers.
