Frequently Asked Questions

What's the difference between expiration and best quality dates?

The expiration date on regular pasteurized milk indicates the last day the milk is guaranteed to be at its peak quality in terms of taste and freshness. Consuming milk after the expiration date may not necessarily make you sick, but the taste and texture may be compromised. Best quality refers to the period during which the milk tastes and looks its best but may still be safe to consume for a few days beyond that date if properly stored.

How can I tell if Regular Pasteurized Milk has gone bad?

To check if regular pasteurized milk has spoiled, look for any signs of curdling, clumps, or a thicker texture than usual. Smell the milk for any sour or off odors, and visually inspect for any changes in color or the presence of mold. If you notice any of these indicators, it's best to discard the milk to prevent any potential foodborne illnesses.

What are the food safety risks?

Regular pasteurized milk is generally considered safe to consume, but there is a risk of contamination if not stored properly.

What are some pro storage tips?

To optimize the storage of regular pasteurized milk, it is important to keep it refrigerated at a temperature of 40°F (4°C) or below.
