Heat: The 5 foods you absolutely need to put in the fridge

There are certain foods that it is necessary to store in the fridge in order to avoid any risk of contamination by pathogens. If some products such as tomatoes, eggs or potatoes do not need to be kept cool, other perishable foods should instead be kept in the refrigerator so as not to break the cold chain.

Indeed, from 4°C, the growth of bacteria is limited and – 18°C, their multiplication stops completely and they become inactive. Which foods must therefore be stored in the fridge to avoid any risk of contamination by pathogens?


The freezer is the perfect way to store meat. It is possible to keep the pieces of beef there for several months while maintaining an average temperature of minus 18°C. The stored pieces can be placed in trays or frozen in their original packaging. As for the meats already cut, the shelf life in the refrigerator can extend over several days at a maximum temperature of 4°C. A word of advice: aluminum foil is not very suitable for wrapping meat, as it could promote its oxidation.

Fish and seafood

Freezing preserves the texture and flavor of seafood. When storing food, it should be distributed so that there is enough for one meal. This avoids having to defrost everything. For fish, it is necessary to gut them before any conservation, because the viscera contain harmful substances that can alter the flesh. If you put fish and seafood in the refrigerator, the ideal temperature is between 0°C and 2°C. They should then be consumed within 48 hours so as not to lose any of their taste qualities.

Psssssst :  Lose weight with living food!


Cheeses, especially fresh cheeses, can be stored in the refrigerator. A maximum temperature of 4°C is perfect, because you should know that a temperature that is too high or too low risks altering its texture and taste. For less fragile and matured cheeses, the coolness of the vegetable drawer is sufficient, but it is possible to store them in a cellar as long as the coolness remains moderate. To better taste the cheese, it is a good idea to take it out of the refrigerator about one to two hours in advance.

Dairy products

Besides cheese, other dairy products like yogurt should be stored in the fridge. It is imperative to respect the cold chain to avoid the proliferation of pathogenic germs, especially since these are products derived from living organisms. The right temperature for storing dairy products can vary depending on the nature of each food, but it should be remembered that yogurt and cheese need a maximum temperature of 4°C while creams, milk and butter can be stored. at a maximum of 6°C. For products that are not sold in the fresh section, storage in the refrigerator remains necessary once they are started.

Dishes and sauces

Dishes such as potato salad, ready meals, dishes with mayonnaise or leftover meals should be kept in the refrigerator to avoid any risk of contamination. If homemade mayonnaise should be consumed within 24 hours, prepared vegetables and cooked fish can stay there for 2 days. To preserve a cooked dish, it is advisable to wait until it cools down before putting it in the fridge. Be careful, however, not to exceed a waiting period of 2 hours to protect it from any risk of contamination.
