Frequently Asked Questions

What's the difference between expiration and best quality dates for Unopened Packaged Mozzarella?

The expiration date on packaged mozzarella indicates the last day the product is guaranteed to be at its peak quality in terms of taste and texture. Consuming mozzarella past this date may result in a decline in quality, such as changes in flavor, texture, and potential spoilage. However, it does not necessarily mean the product is unsafe to eat. On the other hand, the best quality date refers to the period during which the mozzarella is expected to taste its freshest and have the best texture. It is advisable to consume mozzarella before the best quality date for optimal enjoyment.

How can I tell if Unopened Packaged Mozzarella has gone bad?

To check if unopened packaged mozzarella has gone bad, look for any signs of mold or discoloration on the surface. Sniff the cheese for any sour or unpleasant odors. If the mozzarella feels slimy or sticky to the touch, it is likely spoiled and should be discarded.

What are the food safety risks with Unopened Packaged Mozzarella?

Unopened packaged mozzarella carries a risk of contamination by bacteria such as Listeria monocytogenes, which can cause serious foodborne illness, especially in vulnerable populations like pregnant women, elderly individuals, and those with weakened immune systems. It is crucial to store mozzarella properly and adhere to expiration dates to minimize these risks.

What are some pro tips for storing Unopened Packaged Mozzarella?

To extend the shelf life of unopened packaged mozzarella, store it in the refrigerator at a temperature of around 40°F (4°C). Keep the cheese in its original packaging or transfer it to an airtight container or resealable bag to prevent moisture loss and absorption of odors. Avoid freezing mozzarella as it can alter the texture and affect its taste. If the cheese develops mold or an off smell, discard it immediately to prevent foodborne illness.
