7. Shredded Cheddar Cheese
According to Eat By Date, an opened package of semi-hard cheese such as shredded cheddar will last for about two weeks in the refrigerator. Keep shredded cheese in a resealable plastic bag to prevent the shreds from drying out and hardening. Store unused portions of shredded cheddar in the freezer and it will last for six to eight months.
6. Processed Cheese Products
Sadly, the contents of processed cheese products bear little resemblance to real cheese. These items are commonly found sitting at room temperature on grocery store shelves. Canned spray cheese, jars of cheese spread, and blocks of pasteurized cheese product may be made from powdered cheese, whey, and milk proteins. Cheese products can be left at room temperature until they are opened. Even then, the preservatives they contain can prevent spoilage at room temperature for longer periods of time.
5. Cottage Cheese and Ricotta Cheese
Cottage cheese and ricotta cheese are soft cheeses in whey that typically last about a week after the freshness date on the package. Be sure to keep these cheeses sealed in an airtight container. A funky or sour odor, discoloration, and liquid separation are warning signs that these cheeses have gone bad. Cottage cheese and ricotta can spoil quickly. Therefore, when serving or using these cheeses, be sure to use clean utensils to avoid introducing microbes to the container.Related: 12 Helpful Hints for Storing Your Produce to Maintain Freshness
