How to Store a Cut Onion Safely

Cut onions can be a convenient addition to many meals, but they can also be a breeding ground for bacteria if not stored properly. Up to 90% of onions used in cooking are contaminated with Salmonella, a bacteria that can cause serious food poisoning. To minimize the risk of contamination and keep your onions fresh, follow these steps on how to store a cut onion safely.

Choosing the Right Container

When it comes to storing cut onions, the right container can make all the difference. Look for a container that is airtight and made of a material that can be easily cleaned, such as glass or plastic. Avoid using containers with small openings or holes, as these can allow bacteria to spread and contaminate the onion.

Storing Cut Onions in the Refrigerator

Refrigeration is one of the best ways to store cut onions. Cut onions can be stored in the refrigerator for up to 5-7 days. To store cut onions in the refrigerator, follow these steps:

• Place the cut onion in an airtight container.
• Add 1-2 tablespoons of vinegar or lemon juice to the container to help prevent bacterial growth.
• Cover the container with a lid or plastic wrap.
• Store the container in the refrigerator at a temperature of 40°F (4°C) or below.

Storing Cut Onions at Room Temperature

If you don’t have access to a refrigerator or prefer not to store cut onions in the refrigerator, you can store them at room temperature. Cut onions can be stored at room temperature for up to 2-3 days. To store cut onions at room temperature, follow these steps:

• Place the cut onion in an airtight container.
• Add 1-2 tablespoons of vinegar or lemon juice to the container to help prevent bacterial growth.
• Cover the container with a lid or plastic wrap.
• Store the container in a cool, dry place away from direct sunlight.
