Leuconostoc bacteria play a big role in making many foods we eat. They help create the special flavors and textures in fermented foods.

How Leuconostoc Helps Make Food

Can Leuconostoc Cause Problems?

Most of the time, Leuconostoc bacteria are helpful or harmless. However, sometimes, they can cause issues. For example, if they grow too much in food, they can spoil it. They might make food taste bad or look slimy.

In rare cases, Leuconostoc can cause infections in people. This usually happens only if someone is already very sick or has a weak immune system. It is not common for healthy people to get sick from these bacteria. Doctors use special tests to find out if Leuconostoc is causing a problem.
