Virus Testing in Fresh Leafy Herbs and Vegetables

829 samples of fresh leafy herbs and 230 samples of fresh leafy vegetables were tested for Hepatitis A and Noroviruses by the Canadian Food Inspection Agency. 99.9% of herb samples and 100% of vegetable samples were found to be satisfactory. The surveys cover two periods: April 2017 to March 2018 and April 2020 to March 2021.

Use Cases

• Analyze virus detection rates between product types (fresh leafy herbs vs. fresh leafy vegetables).
• Compare pathogen prevalence across survey periods (2017-2018 vs. 2020-2021).
• Assess food safety compliance using the satisfactory sample rate metric.

Strengths

• 1,059 total samples tested across two product categories.
• Clear temporal coverage across two distinct survey periods.
• Results include specific satisfactory rates (99.9% and 100%).

Limitations

• Sample size for fresh leafy vegetables (230) is relatively small.
• No column-level detail is provided to analyze specific virus types or sample attributes.
• Data is aggregated into final report percentages, limiting granular analysis.
