It says there have been reported reactions associated with the consumption of the product.

A food safety investigation is underway, conducted by the CFIA. It says this investigation could lead to further recalls.

“The CFIA is verifying that industry is removing recalled products from the marketplace,” it says.

The CFIA says the recalled products should not be consumed if you are allergic or sensitive to pistachios, as they “may cause a serious or life-threatening reaction.”

Recalled products can be thrown out or returned to the place of purchase, it says.
