[h3]Safety Guidelines for Vacuum Sealing Food[/h3]
If you have taken proper steps in preparing your food in a clean and uncontaminated environment, then this should not be a problem. However, if there is any question about the safety, then err on the side of caution and do not vacuum pack the food, as you would be creating a perfect breeding ground for bacteria.
Follow these guidelines to properly vacuum seal food:
Vacuum sealing food does not replace the need to pressure can or water bath home canned foods.
Wash hands before and during the vacuum sealing process.
Try not to touch food with your hands. Use clean spoons, tongs or something else to handle the food.
Be sure to keep utensils, cutting boards and counters clean.
Keep vacuum sealed foods in the refrigerator or freezer. Dry food, like crackers and nuts, can be stored at room temperature.
Freeze low-acid vacuum packaged foods and consume immediately after heating. Never heat a low-acid vacuum packaged food and allow it to stand at room temperature in the vacuum package.
Ensure that you do not cross contaminate food.
Properly label food sources with type of food and date packaged.
Ensure the seal is complete and that there is no debris in the seal.
