Frequently Asked Questions

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

The expiration date on cottage cheese indicates the last date recommended for consumption for safety reasons. Consuming cottage cheese after the expiration date can pose health risks due to potential bacterial growth. On the other hand, the 'best quality by' date refers to the period during which the product is expected to retain optimal taste and texture. Consuming cottage cheese after the best quality date may not be harmful but might result in diminished flavor and texture.

How can I tell if Cottage Cheese has gone bad?

To determine if Cottage Cheese has gone bad, look for signs of mold, a sour or off smell, or an unusual slimy or curdled texture. If you notice any of these indicators, it is best to discard the Cottage Cheese to avoid the risk of foodborne illness.

What are the food safety risks?

Cottage cheese, being a dairy product, is susceptible to contamination by harmful bacteria such as Listeria, Salmonella, and E. coli if not stored properly. Always make sure to refrigerate cottage cheese promptly after purchase and consume it before the expiration date to reduce the risk of foodborne illnesses.

What are some pro storage tips?

To prolong the shelf life of cottage cheese, always store it in the coldest part of the refrigerator, preferably at a temperature below 40°F (4°C). Keep cottage cheese tightly sealed in its original container or an airtight container to prevent absorption of odors from other foods in the fridge. If the liquid separates from the curds, simply give the cottage cheese a stir before serving to redistribute the moisture.
