Canning at Retail in Minnesota (PDF)
Canning can be a safe and economical way to preserve and add value to fruits and vegetables. The most common biological hazards specific to canning include botulism toxin as well as yeast and mold (mycotoxins).
Hazard analysis critical control point (HACCP) plans are required for canning at retail in Minnesota. You must follow Minnesota food code requirements and any applicable local ordinances when canning in your retail establishment.
This Web page highlights important requirements and safety considerations for food establishment operators who want to preserve food for storage at room temperature in Minnesota.

Here are some examples of foods you may can at retail. If you don’t see a food you would like to can, contact your inspector.
Jams, Jellies & Preserves
- Raspberry jam
- Pepper jelly
- Strawberry preserves
Naturally Acid Foods
- Raspberries, peaches or plums
- Flavored vinegars
Acidified Fruit & Fruit Products
- Apple butter
- Watermelon pickles
Tomatoes & Tomato Products
- Crushed or whole tomatoes
- Tomato juice
- Barbeque sauce or ketchup
- Cucumber pickles
- Pickled beets or peppers
- Dilly beans
- Fermented pickles
*You must have an additional and separate HACCP plan for the fermentation process.
If you want to can low-acid foods, you must follow special requirements found in Code of Federal Regulations, title 21 (21 CFR).
- Beans, corn, potatoes or squash
- Poultry, red meat or seafood
You must have and follow an approved HACCP plan. Because of naturally-occurring variations in acidity (pH) between and among fruits and vegetables, it is important that you follow an approved recipe and process when canning these foods.
You may use a standard recipe and process from:
- Ball® Blue Book™
- USDA Complete Guide to Home Canning
- National Center for Home Food Preservation
- A University Extension Service
You may use a custom recipe and process approved by a competent processing authority. A processing authority is a person or organization having expert knowledge of thermal processing requirements for foods in hermetically sealed containers, and who also has access to a testing facility for making such determinations.
Contact your inspector if you have questions about your recipe and process or a processing authority.
Your recipe and process must be scientifically validated to confirm the process is safe.
- If your HACCP plan is based on a standard recipe, no additional scientific documentation is required.
- If your HACCP plan is based on a custom recipe, you must provide additional scientific documentation as required by the processing authority and/or regulatory agency. The data must show that your recipe and process provides safe food.
Remember, your recipe and process is part of your HACCP plan and cannot be changed without review and approval.
You must include standard operating procedures (SOPs) in your HACCP plan. SOPs for canning at retail typically include:
- Processing equipment specifications, and pH meter specifications and calibration
- Container specifications and sterilization
- Fruit and vegetable preparation
- Processing steps
- Preparation of product slurry and pH testing
You must include a critical limit and corrective action for each critical control point (CCP) in your HACCP plan. For canning at retail, these typically include:
|CCP||Critical Limit||Corrective Action|
|Thermal processing||Times/temperatures in approved recipe||
Re-process or discard product
|Finished product pH||pH 4.6 or lower||
|Allergen labeling||Allergens identified||
If you want to wholesale your product, or sell your product via internet or across state lines, you will need to meet additional regulatory requirements. See: Dairy & Food Inspection Division.
Canning - A process used to preserve food in sealed jars for storage at room temperature.
pH - A measure of the degree of acidity or alkalinity of a solution.
Acid food - Food that has a natural pH of 4.6 or below.
Low-acid food - Any food with a pH greater than 4.6.
Acidified food - Low-acid food to which acid or acid food is added to reduce the pH to 4.6 or below.
Fermented food - Low-acid foods subjected to the action of certain microorganisms, which produce acid during their growth and reduce the pH of the food to 4.6 or below.
