Bacterial pathogens and indicators in powdered infant formula - April 1, 2018, to March 31, 2024

Abstract

A 6-year (April 1, 2018, to March 31, 2024) targeted survey analysed 898 samples of powdered infant formula for the presence of the pathogen Cronobacter spp. Of the 898 samples, 479 were also tested for the pathogen Salmonella spp. All 898 samples were also tested for Enterobacteriaceae, which is used as an indicator of the hygienic and sanitary conditions of the food supply chain from production to the point of sale. 99.7% of the samples tested were found to be satisfactory. Salmonella spp. was not detected in any (0 of 479) of the samples. Cronobacter spp. was detected in 1 of 898 (0.1%) samples. Enterobacteriaceae was detected in 2 of 898 (0.2%) samples. The Canadian Food Inspection Agency conducted appropriate follow-up activities and food recalls were issued by industry. There were no reported illnesses related to these products. Overall, our survey results indicate that powdered infant formula sold in Canada is generally safe for consumption. However, as with all food, and especially those that are intended for infants, good hygienic practices are recommended for producers, retailers, and consumers.
