Safe food handling during proper cleaning of vacuum sealers

When it comes to preserving our favorite foods through canning, we often focus on the ingredients and recipes. However, it’s essential to understand that safe food handling practices are equally important. One crucial aspect of food safety during canning is the proper cleaning of canning jars. In this blog, we will explore why safe food handling is crucial and delve into the significance of thorough jar cleaning to ensure food safety.

Understanding Food Safety

Potential risks of improper food handling
Improper food handling during canning can lead to various risks, including bacterial contamination, mold growth, and spoilage. Consuming improperly processed or contaminated food can cause foodborne illnesses, leading to gastrointestinal problems, vomiting, diarrhea, and, in severe cases, even hospitalization.

Why cleanliness is crucial in canning
Cleanliness plays a pivotal role in canning as it helps eliminate harmful bacteria, yeast, molds, and other contaminants that can compromise the safety and longevity of canned goods. Properly cleaned canning jars provide a clean slate for preserving food, minimizing the risks of spoilage and foodborne illnesses.

Preparing the Canning Jars

Gather necessary supplies
Before beginning the cleaning process, gather all the necessary supplies, including warm water, mild dish soap, a clean brush or sponge, clean towels, and sanitizing agents such as boiling water or a dishwasher.

 Inspect the jars for any damages
Check each canning jar for cracks, chips, or other damages that could impact their integrity. Damaged jars should be discarded to prevent potential breakage during canning.

Washing the jars

Using hot, soapy water: Start by washing the jars in hot, soapy water. Ensure you cover all surfaces, including the inside and outside of the jar, the rim, and the threads. Remove any visible debris or residue.
Paying attention to hard-to-reach areas: Pay special attention to hard-to-reach areas, such as the bottom of the jar or the ridges. A clean brush or sponge can help remove any stubborn residue or dirt.
Rinsing thoroughly to remove soap residue: Thoroughly rinse the jars with warm water to remove all soap residue. Soap residue can affect the taste and quality of the preserved food.
Sanitizing the jars

Methods for sanitizing: There are different methods for sanitizing jars, such as boiling them in water or using a dishwasher. Boiling the jars in water for 10 minutes can effectively kill bacteria and sanitize the jars. Alternatively, you can run the jars through a dishwasher cycle using high heat.
Ensuring complete coverage of jar surfaces: Whatever method you choose, ensure that all jar surfaces, including the interior and exterior, are thoroughly sanitized.
Air drying the jars: After sanitizing, allow the jars to air dry completely before using them for canning. Using a clean towel to dry them may introduce unwanted contaminants.
Handling the Jars Properly

Clean and sanitized work area
Maintain a clean and sanitized work area to minimize the risk of contamination. Clean countertops, cutting boards, and any other surfaces that will come in contact with the jars or food.

Using clean utensils and equipment
Only use clean utensils, such as ladles, funnels, and tongs, when handling the jars and transferring food. Wash them with hot, soapy water before each use.

Avoiding cross-contamination
Prevent cross-contamination by keeping raw ingredients, such as fruits or vegetables, separate from other foods, and wash your hands thoroughly after handling raw ingredients to minimize the transfer of bacteria.

Proper storage of cleaned jars before use
Store cleaned jars in a clean and dry area, preferably covered, until you are ready to use them. This prevents dust or other contaminants from settling on the sanitized jars.

Maintaining Hygiene While Filling Jars

 Clean hands and work surfaces
Before filling the jars, wash your hands thoroughly with soap and warm water. Ensure your work surfaces are clean and free from any potential contaminants.

Using sanitized utensils for filling
Use sanitized utensils, such as ladles or spoons, to transfer the food into the jars. This helps prevent the introduction of bacteria or other pathogens during the filling process.

Preventing food spills and drips
Clean any spills or drips promptly to maintain a clean and safe canning environment. Spills or drips can attract pests or promote bacterial growth.

 Tightening jar lids securely
Ensure the jar lids are tightened securely but not overly tightened. Over-tightening can interfere with the proper sealing process.

Additional Tips for Safe Food Handling

Labeling and dating the jars
Label each jar with the contents and the date of canning. This helps you keep track of the freshness and rotation of your canned goods.

Storing jars in a cool, dark place
Store your canned goods in a cool, dark place away from direct sunlight. Excessive heat and light exposure can compromise the quality and safety of the preserved food.

Regularly checking for signs of spoilage
Periodically check your canned goods for signs of spoilage, such as bulging lids, off-putting odors, or mold growth. Discard any jars that show signs of spoilage to avoid consuming unsafe food.

Following recommended processing times and methods
Adhere to recommended processing times and methods for canning various foods. Different foods require specific processing techniques to ensure proper preservation and safety.


Safe food handling practices are vital when it comes to canning. Properly cleaning canning jars plays a crucial role in ensuring the safety and longevity of preserved foods. By following the guidelines outlined in this blog, you can minimize the risk of contamination, spoilage, and foodborne illnesses. Remember, prioritize food safety in your canning practices to enjoy delicious, safe, and healthy homemade canned goods.
