Should I refrigerate an open can of kidney beans?

Yes, you should refrigerate an open can of kidney beans. After opening a can of kidney beans, it is important to store the beans in the refrigerator to prevent the growth of harmful bacteria. Kidney beans contain a type of protein called phytohemagglutinin, which can cause food poisoning if consumed in large quantities. Refrigerating the beans will help to slow down the growth of bacteria and prevent the production of phytohemagglutinin.

To store kidney beans, transfer them to a clean, airtight container and place them in the refrigerator. The beans can be stored for up to 3-4 days in the refrigerator. When you are ready to use the beans, be sure to heat them thoroughly to an internal temperature of 165°F (74°C) to kill any harmful bacteria.
