An expiration date is not the same as a best-before date. Expiration dates are required only on certain foods that have strict compositional and nutritional specifications which might not be met after the expiration date.
Expiration dates must be used on the following products:
- formulated liquid diets (nutritionally complete diets for people using oral or tube feeding methods)
- foods represented for use in a very low-energy diet (foods sold only by a pharmacist and only with a written order from a physician)
- meal replacements (formulated food that, by itself, can replace one or more daily meals)
- nutritional supplements (food sold or represented as a supplement to a diet that may be inadequate in energy and essential nutrients)
- human milk substitutes (infant formula)
After the expiration date, the food may not have the same nutrient content declared as on the label.
Food should not be bought, sold or eaten if the expiration date has passed. It should be discarded.
