The FDA is recalling a popular snack after a fatal flaw was discovered.

The Food and Drug Administration found that eating a particular brand of cookie could cause “a reasonable probability of death.”

Cookies produced by J.Sweets, which does business as Jalux Americas Inc, were found to have undeclared milk and tree nuts not listed on the ingredients label.

The FDA’s first recall was issued on July 14.

In the initial notice, the agency wrote that “people who have an allergy or severe sensitivity to milk and/or tree nuts (almond and macadamia nuts) run the risk of serious or life-threatening allergic reaction if they consume these products.”

Since the notice was published, the FDA has upgraded the warning to a Class 1, the highest level of notice. 

“People who have an allergy or severe sensitivity to milk and/or tree nuts (almond and macadamia nuts) run the risk of serious or life-threatening allergic reaction if they consume these products,” the FDA reported.

Those who are allergic to the undeclared products could have a severe allergic reaction, which can cause difficulty breathing, rashes, or even death. 

The treats being recalled are the L’espoir and Drycapot cookies.  

The cookies being recalled were sold in California, Illinois and Washington.

The L’espoir products were sold between May 26 and June 30, and the Drycapot, containing undeclared tree nuts, was sold at J.sweets stores between May 31 and June 30, 2025.

According to J. Sweets, no illnesses were reported due to the mislabeling. 

“The recall was initiated after it was discovered during an inventory audit that L’espoir product containing Milk and the Drycapot product containing Tree Nuts were inadvertently distributed in packaging that did not reveal the presence of those allergens,” the company wrote in its recall notice.

“This recall is being made with the knowledge of the U.S. Food and Drug Administration.”

Consumers who bought the products can return them for a full refund.

 “Those who have allergies to the ingredients that were inadvertently undeclared on the labels should refrain from consuming the products and return them to the store where they purchased for a full refund,” the company told Newsweek. 

“As part of our preventive measures, our supplier partner has added a step at their manufacturing facility to verify that the product matches the label after it is applied, and to record this verification in the production log.

“Our supplier partner will also reinforce allergy and manufacturing procedure training at the facility.

“At the retail store level, we will strengthen our checks during stocking to ensure there are no discrepancies between products and labels, not just for the manufacturer of the recalled products but across all items.”

The company added: “We would like to clarify that we have thus far not received any inquiries from consumers regarding this matter.”

The cookies were exclusively sold at J.sweets retail locations in Torrance, CA, and San Jose, CA, Arlington Heights, IL; and Lynnwood, WA. 

None of the mislabeled products were sold online.
