The risks of an open can of food in the fridge

 

Find out why it’s crucial to reseal canned goods before placing them in the refrigerator to preserve food quality and avoid health problems.

Let’s find out why it’s crucial to avoid this practice and what options to consider as an alternative.

The harmful effects of keeping an open can of food in the refrigerator:

1. A risk of food poisoning:
As soon as a can of food is opened, its contents are exposed to air and moisture, thus promoting the oxidation of metals (aluminum, tin). This chemical reaction can release harmful substances that mix with the food, resulting in an unpleasant metallic taste and a potential health risk.

In addition to oxidation, dangerous bacteria can grow on the edges of the can, increasing the risk of food poisoning with bacteria such as Salmonella, E. coli, Listeria, and Botulism.

 Favored bacterial proliferation:

Contrary to popular belief, the refrigerator doesn’t completely stop the growth of bacteria; it slows it down. An open can of food exposes it to air and moisture, ideal conditions for the growth of microorganisms, increasing the risk of contamination if the can remains open for too long.

3. Altered taste and texture:
Leaving food in its can after opening can give it a metallic taste due to oxidation of the metal when exposed to air and moisture. Some foods, such as fruits or sauces, can absorb metallic elements, altering their taste and texture.

4. Avoidable food waste:

An opened can of food in the refrigerator often leads to unnecessary waste because over time, the food’s appearance, smell, and taste change, often prompting its disposal. It is recommended to immediately transfer leftovers to an airtight container and note the opening date for prompt consumption, preferably within 2-3 days.

– Use an airtight container made of glass or food-grade plastic.
– Make sure to close the container tightly to prevent contamination and loss of freshness.
– Store in the coldest part of the refrigerator, below 4°C.
– Consume quickly, preferably within 2 to 3 days.

In conclusion, leaving an open can of food in the refrigerator is a bad habit that can affect your health and food quality. To avoid oxidation, bacteria, loss of flavor, and waste, it’s essential to adopt good storage practices such as transferring food to an airtight container and consuming it quickly. Also, consider freezing leftovers to avoid waste. By taking these precautions, you’re protecting your health and avoiding potential inconveniences.
