Water bath canning is a popular method for preserving fruits, vegetables, and other foods, but it’s not suitable for all types of food. In this article, we’ll explore what you can’t water bath can, and why.
Understanding Water Bath Canning
Before we dive into what you can’t water bath can, let’s quickly review how water bath canning works. Water bath canning involves submerging jars of food in boiling water for a period of time, usually 10-30 minutes, to kill off bacteria and create a vacuum seal. This method is great for high-acid foods like fruits, pickles, and jams, but it’s not suitable for low-acid foods like meats and vegetables.
Why Some Foods Can’t Be Water Bath Canned
There are several reasons why some foods can’t be water bath canned. The main reason is that water bath canning can’t reach high enough temperatures to kill off all bacteria, especially in low-acid foods. Low-acid foods require a higher temperature to kill off bacteria, which is why they need to be pressure canned instead.
Another reason some foods can’t be water bath canned is that they’re too dense or thick. Foods like meats and vegetables are too dense for water bath canning, as they can’t be heated evenly throughout. This can lead to undercooked or raw spots in the food, which can be a food safety issue.
Foods That Can’t Be Water Bath Canned
So, what foods can’t be water bath canned? Here are some examples:
- Meats: Meats like beef, pork, and chicken can’t be water bath canned, as they require a higher temperature to kill off bacteria. This includes soups, stews, and casseroles that contain meat.

Special Considerations for Water Bath Canning
While some foods can’t be water bath canned, there are some special considerations to keep in mind when canning certain foods. For example:
- Acidic foods with low acidity: Foods like tomatoes and peppers are acidic, but they may not be acidic enough for water bath canning. To ensure these foods are safe to eat, you may need to add additional acidity, like lemon juice or vinegar.
- Foods with high water content: Foods like watermelon and cantaloupe have high water content, which can make them more prone to spoilage during the canning process. To ensure these foods are safe to eat, you may need to use a pressure canner or add additional acidity.
Alternatives to Water Bath Canning
If you want to can foods that can’t be water bath canned, there are several alternatives to consider. Here are a few options:
- Pressure canning: Pressure canning is a great way to can low-acid foods like meats and vegetables. This method uses high pressure to kill off bacteria and create a vacuum seal.
- Dehydrating: Dehydrating is a great way to preserve foods like fruits and vegetables. This method uses low heat to remove moisture from the food, making it safe to store for long periods of time.
- Freezing: Freezing is a great way to preserve foods like meats and vegetables. This method uses low temperatures to kill off bacteria and preserve the food.

What foods are not suitable for water bath canning?
Foods that are not suitable for water bath canning are those that are low in acidity and high in protein, as they can provide an ideal environment for the growth of bacteria, particularly Clostridium botulinum. Examples of such foods include meats, poultry, seafood, and dairy products. These foods require a pressure canner to ensure that they are heated to a high enough temperature to kill off any bacteria that may be present.
It’s also important to note that some vegetables, such as green beans, corn, and peas, are not suitable for water bath canning unless they are pickled or acidified in some way. This is because these vegetables are low in acidity and can provide an environment for bacterial growth. However, if you add a sufficient amount of acid, such as lemon juice or vinegar, to the vegetables, they can be safely canned using a water bath canner.
Why can’t I can meat or poultry using a water bath canner?
Meat and poultry cannot be safely canned using a water bath canner because they are low in acidity and high in protein, making them an ideal environment for the growth of bacteria, particularly Clostridium botulinum. Water bath canners are not capable of heating the food to a high enough temperature to kill off these bacteria, which can cause serious illness or even death.
To safely can meat or poultry, you need to use a pressure canner, which can heat the food to a high enough temperature to kill off any bacteria that may be present. A pressure canner can reach temperatures of up to 240°F (115°C), which is hot enough to kill off even the most heat-resistant bacteria. This is why it’s so important to use a pressure canner when canning meat or poultry.
Can I can dairy products using a water bath canner?
No, dairy products should not be canned using a water bath canner. Dairy products, such as milk, cheese, and yogurt, are low in acidity and high in protein, making them an ideal environment for the growth of bacteria, particularly Clostridium botulinum.
