How Long Does Home Canned Food Last?

When it comes to canning food at home, you may be wondering how long your canned goods will last. It is important to know the answer to this question, as canned goods that have been stored too long can become contaminated and unsafe to eat.

The answer to this question is not simple and will depend on several factors, including the type of food that was canned, how it was prepared, and where it has been stored.

When storing food you should always strive for an optimal temperature of 40°F or below. If a lower temperature is not possible, room temperature is acceptable but should not exceed 70°F. The storage area should also be as dry and as dark as possible.

High acid foods such as tomatoes, fruits, pickles, and sauerkraut can usually last 12-18 months when properly canned using the water bath method. Low-acid foods such as meats and vegetables need to be pressure canned in order for them to last up to 5 years when stored properly.

It is important to note that any food that has been stored too long or exposed to temperatures that are too high will become unsafe to eat regardless of the type of canning method used. To avoid this you should check all cans for signs of spoilage before eating them. This includes bulging lids or seams, leaking or swollen cans, or an off-odor coming from the contents of the can.

In summary, home canned food can last up to 18 months for high acid foods and up to five years for low acid foods if they are properly prepared and stored at temperatures below 70°F in a dry and dark area. However it is important to inspect all cans before consuming them in order to ensure they are safe for consumption.

Conclusion: Home canned food can last up to 18 months for high acid foods and up to five years for low acid foods if they are properly prepared and stored at temperatures below 70°F in a dry and dark area. However it is important always check all cans before consuming them in order ensure they are safe for consumption in order to avoid contamination and illness caused by spoiled food products.
