Though no illnesses have been reported so far, the company is taking proactive steps to protect public health.

What Caused the Issue?
The contamination was linked to Listeria monocytogenes, a harmful bacterium commonly found in soil, water, and decaying vegetation. Listeria is particularly dangerous in fresh produce and ready-to-eat foods, as it can survive and even grow in refrigerated conditions. The contamination was discovered through routine product testing conducted by the Canadian Food Inspection Agency.

No illnesses have been reported at the time of the recall, but prompt response and consumer awareness are crucial in minimizing risk.

Behind the Brand
Wiet Peeters Farm Products Limited is a Canada-based producer known for supplying mushrooms across North America under the Peeters and Aunt Mid’s brands. While this may be the first major recall tied directly to Peeters, Listeria-related mushroom recalls aren’t new to the produce aisle:
- On July 7, the FDA issued a food safety alert after Ruck’s Meat Processing voluntarily recalled several ready-to-eat sausage products that tested positive for Listeria monocytogenes.
- On July 2, 2025, Kraft Heinz Foods Company recalled a staggering 367,812 pounds of its Oscar Mayer Turkey Bacon after internal testing flagged the possibility of Listeria monocytogenes contamination.
- On June 20, 2025, Oregon-based Face Rock Creamery voluntarily recalled its Vampire Slayer Garlic Cheddar Curds after internal routine testing flagged the presence of Listeria monocytogenes.
- On June 17, 2025, FreshRealm recalled its Chicken Fettuccine Alfredo products after FSIS linked them to a multi-state Listeria monocytogenes outbreak.
- On June 11, 2025, Hofood99 Inc. recalled its 200g Enoki Mushrooms after discovering Listeria monocytogenes in a sample collected in Michigan.
“It just takes one contaminated batch to trigger a recall of this scale. This case highlights the essential role of traceability, rigorous safety protocols, and transparent communication throughout the supply chain to prevent food safety risks.” said Eran Mizrahi, CEO of Source86.
These trends show that mushroom processing lines are particularly vulnerable, making traceability and equipment sanitation more critical than ever.
Ensuring Safe Eats
This recall underscores the high stakes of food safety, especially for bulk produce suppliers and private label manufacturers. For companies sourcing or packing mushrooms, the takeaway is clear: robust sanitation protocols and early pathogen detection systems are essential.
To recap:
- Sanitize equipment regularly
- Improve traceability and supplier oversight
- Test batches frequently—do not wait for a problem
- Act swiftly with public communication if contamination is detected
