The Canadian Food Inspection Agency (CFIA) says a baby formula sold online and at Costco is being recalled due to concerns of a toxin that can cause food poisoning.

The federal agency said the one-kilogram containers of Kendamil brand infant formula that have “with whole milk” on the label may contain cereulide, a toxin which can quickly cause nausea and vomiting.

Cereulide is not destroyed by heat and can survive temperatures that would usually kill bacteria.

The CFIA said no one has reported getting sick and that the recall was triggered by one in another country.

Amazon also listed the recalled baby formula on its website as of Monday.

Nestle and Danone recently issued baby formula recalls due to the possible contamination of the same toxin.

European-based company Kendal Nutricare said cereulide has been recently associated with arachidonic acid oil, a source of Omega 6, and that during a short supply disruption, the company used a different oil supply than usual for two batches of infant formula sold at Costco in Canada.

Those batches were produced in May 2025 and their codes — 897274 and 888632 — can be found on the base of the tin.

The company said these batches still pass the European safety guidance for cereulide levels in infant formula, but Health Canada has a different standard.

Kendamil’s notice states: “Health Canada has requested this precautionary withdrawal of any batches whose ingredient source could in theory be impacted. This is irrespective of lab testing results for the specific batches that demonstrate compliance with strict safety limits set by the scientific community and now being adopted internationally.”
