Beetle concerns in pre-packaged salads
The agency is investigating consumer complaints of Iron Cross Blister beetles in pre-packaged salads.
There have been no confirmed illnesses or injuries.
The Iron Cross Blister beetle is coloured with a bright red head and bright yellow markings on the wings, separated by a black "cross".
CFIA said the beetle should be treated with caution as it may release an irritating chemical called "cantharidin" which can cause blisters at the point of contact.
Fresh produce can harbour insects that may injure to consumers, but this is rare, said the agency.
Consumers are advised to wash and visually inspect leafy vegetables thoroughly. The beetle should be removed without touching or crushing it and the local CFIA office should be told.
