Canadian Raw Milk Cheese Pathogen Survey 2014-2018

Canadian Food Inspection Agency targeted surveys analyzed 2,009 raw milk cheese samples for bacterial pathogens from November 2014 to March 2018. The dataset includes test results for E. coli O157, generic E. coli, Salmonella, Staphylococcus aureus, and Listeria monocytogenes. It documents findings and subsequent food safety actions.

Use Cases

• Analyze prevalence rates of Staphylococcus aureus and Listeria monocytogenes across the 1,723 tested samples.
• Model the absence of Salmonella, E. coli O157, and generic E. coli in the 2,009-sample survey.
• Study the relationship between pathogen detection and subsequent recall activities documented by the CFIA.
• Compare contamination levels across different sampling periods within the 2014-2018 timeframe.

Strengths

• Results from 2,009 analyzed cheese samples provide a substantial sample size.
• Testing covered five specific pathogens: E. coli O157, generic E. coli, Salmonella, Staphylococcus aureus, and Listeria monocytogenes.
• Clear temporal coverage from November 30, 2014, to March 31, 2018.

Limitations

• Specific sample metadata (e.g., cheese type, producer, region) is not described in the provided information.
• The dataset represents a single targeted survey, not continuous national monitoring.
• Raw sample data or column-level details are unavailable.
