美國聯邦法規不要求於生鮮雞肉標示日期，但許多商店和加工廠自願在雞肉或
雞肉產品包裝上標示期限。 如果有標示日期，則必須有一個與該期限緊鄰的短語，
例如 : "此之前必須銷售或之前使用"。

可使用期限的設定是為了品質保證; 在此日期之後，品質開始降低，但仍可使用該產品。
在到期之前購買產品總是最好的。 如果在雞肉冷凍時使用日期到期，仍然可以使用食物，
因為連續冷凍的食物是安全的。

Dating of Chicken Products

Product dating is not required by Federal regulations, but many stores and
processors voluntarily date packages of chicken or chicken products.
If a calendar date is shown, there must be a phrase immediately
adjacent to the date that explains the meaning of
that date, such as sell by or use before.

The use-by date is for quality assurance; after the date, peak quality
begins to lessen, but the product may still be used. Its always best
to buy a product before the date expires.
If a use-by date expires while the chicken is frozen, the food can still
be used because foods kept frozen continuously are safe indefinitely.
