Industry regulator, Canadian Food Inspection Agency (CFIA) has said that it has launched an investigation into reports that a blister-causing beetle was found in pre-packaged salads by some of the customers.

The iron cross blister beetle can be identified with its bright red head and bright yellow wings separated by a black cross. It can also release an irritating chemical called cantharidin that can cause blisters to the human skin.

The agency said that it is normal to see insects in fresh produce but it is rare to find such insect in packed salads.The CFIA did not specify which brand or brands of salad that are affected and only said that it was imported leafy vegetables. The agency has advised consumers to inspect and wash the produce carefully and asked them not to touch or crush any beetles and only call CFIA. The agency asked consumers to be careful while opening such products and wash them with care. They asked them to avoid contact with the insect.

The agency pointed out that there have not been any reports of illness or injury associated with the products.
