How long after best if used by date is chicken OK?

The answer depends on various factors such as the type of chicken product, how it was stored, and how it was handled before and after the "best if used by" date. Here is a general guideline, but it's always best to err on the side of caution and discard chicken that appears spoiled:

- Fresh Chicken: Refrigerated raw chicken can generally last 1-2 days past its "best if used by" date if it was stored at a temperature of 40°F (4°C) or below.

- Cooked Chicken: Cooked chicken, such as roasted chicken or chicken dishes, can usually last 3-4 days past its "best if used by" date when properly refrigerated.

- Frozen Chicken: Frozen chicken, if properly wrapped and stored at 0°F (-18°C) or below, can maintain its quality for several months. However, it's always best to check the packaging and follow any specific storage instructions.

Remember that the "best if used by" date is a quality indicator and not a safety indicator. It means that the product is at its best quality before that date. After the date, the quality may start to decline, but it doesn't necessarily mean it's unsafe to consume.

Here are signs of spoilage in chicken that may indicate it's no longer safe to eat:

- Unpleasant odor: If the chicken has a strong, sour, or unpleasant smell, it's likely spoiled.

- Slime on the surface: A slimy texture or excessive moisture on the surface can be a sign of spoiling.

- Color changes: Raw chicken should have a pink color. If it has turned gray, green, or has dark spots, it's best to discard it. Cooked chicken should be white or light brown. If it has turned gray or developed dark areas, it's not safe to eat.

- Mold growth: If you notice any mold on the chicken, discard it immediately.

When in doubt, it's always better to throw out the chicken to avoid any potential foodborne illness.
