In response to yesterday's post about mygrocerydeals.com, I've received some additional information from mygrocerydeals.com about how they designate items as "contains" or may contains". It's so helpful to have these definitions. A big thanks goes to Mr. Hladkowicz, Vice President Business Development at mygrocerydeals.com, for clarifying.
"In respect to your query, MyGroceryDeals uses the package information and ingredients list as the basis of identifying whether an item contains one of the eight most common food allergens (Peanuts, Tree Nuts, Fish, Shellfish, Egg, Gluten/Wheat, Soy, Milk). The current database contains over 70,000 items and will continue to grow as the database expands. With respect to how MyGroceryDeals displays allergens, two different flags are used. A red flag denotes those items that contain a specific allergen that the user has identified in their profile, whereas the yellow flag denotes those items that contain any allergen. Given that many manufacturers use the phrases “may contain” or “ may have come into contact with”, where indicated, MyGroceryDeals uses this information as well in determining which items to flag."
