Can You Get Food Poisoning From Canned Olives?

Canned olives are a convenient and tasty way to add flavor to meals, but there is a risk of getting food poisoning from them. Canned olives are typically stored in brine, which is a salty solution that can help preserve the olives and keep them from spoiling.

The brine also creates an environment where bacteria can grow and cause food poisoning. In addition, canned olives can be stored for long periods of time, which increases the risk of contamination.

The main concern with canned olives is botulism. Botulism is a type of food poisoning caused by the bacteria Clostridium botulinum.

This bacteria produces a toxin that can cause serious illness if ingested. Symptoms of botulism include nausea, vomiting, blurred vision, difficulty swallowing and breathing, and paralysis.

It’s important to note that not all canned olives are at risk of causing food poisoning. If you purchase your canned olives from a reputable source and follow storage instructions carefully, you should be able to enjoy them without worry. However, it’s best to err on the side of caution and check the expiration date on any canned products before you purchase them.

If you do get sick after eating canned olives, it’s important to seek medical attention right away. Botulism can be fatal if not treated quickly.


While it is possible to get food poisoning from canned olives, following proper storage instructions and purchasing them from reliable sources will help reduce your risk. If you experience symptoms after eating canned olives, seek medical attention right away.
