Food Microbiology - Targeted Survey - Final Report - Bacterial pathogens and indicators in bulb onions - April 1, 2021, to March 31, 2024

A targeted survey analyzed 2649 samples of bulb onions over a 3-year period from April 1, 2021, to March 31, 2024, for the presence of the pathogens 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 2649 samples tested were found to be satisfactory. Salmonella spp. and E. coli O157 were not found in any of the samples. Generic E. coli at elevated levels (>100 MPN/g) were not found in any of the samples.
