Canning is a high-heat process that renders the food commercially sterile.
Packing is important to the quality and appearance of frozen foods.
Products exposed to air can develop “freezer burn" which does not affect the safety of the product, but can impact the taste and quality. Cans must exhibit a packing code to enable tracking of the product in interstate commerce.
There are two types of dating that are usually displayed on a food product: "Open dating" and "Closed or coded dating." Even if the "use by" or "sell by" date hasn't passed, foodborne pathogens can still contaminate foods that aren't properly stored and handled.
Always wash your hands, separate raw foods from ready-to-eat foods, cook to proper temperatures and refrigerate foods promptly.
The acid content of the food and the lining of the can are important factors in a product's quality and appearance after long periods of storage. Once a perishable product is frozen at the proper temperature, it does not matter if the date expires because food kept frozen continuously is safe indefinitely.
Byler's freezes all packaged items before the expiration date which extends the life.
And remember, if you still aren't sure how old something is or if it is safe to eat: When in doubt, throw it out!
- Open Dating - The most common form of dating is referred to as “open dating." Open dating uses a calendar date, as opposed to a code on a food product.
Open Dating (calendar date as code) is stamped on a food product a product's package.
