Canadians with food allergies are getting more help to steer clear of potentially harmful ingredients.

New federal food labelling regulations take effect across the country tomorrow, requiring manufacturers to clearly identify the presence of ingredients that could cause an allergic reaction.

Health Canada lists 10 “priority” food allergens in the regulations, including peanuts, eggs, milk, tree nuts, wheat, soy, sesame seeds, seafood and sulphites.

Mustard was also recently added to the list.
