You should check the list of the recalled foods because only some Natural Balance pet foods co-packed at the Castleberry’s facility are involved. The FDA tells us that, while botulism can affect some pets, dogs and cats are inherently resistant. The disease has only been seen occasionally in dogs and has not been reported in cats. Ferrets, though, are highly susceptible to botulinum toxin.

Pickles, pickled beets, sauerkraut, jams, jellies, and salsas should NOT be canned under pressure. They should be preserved by using the boiling water method. This process results in a more acceptable product.

Freezing does not cause food spoilage unless the seal is damaged or the jar is broken. These often happen as the food expands during freezing. Frozen foods, however, may be less palatable than properly stored canned food. In an unheated storage place, protect canned foods by wrapping the jars in paper or covering them with a blanket.

While we cannot guarantee these canned foods will last this long, you really should read about the canned food taken to the Arctic in 1820 . . . and opened in 1938, and found still to be edible. That's after 118 years with a can produced when canning technology was about 10 years old! I know you're busy and have no spare time (the average time people spend on our website is 3 1/2 minutes), but you really owe it to yourself to read this page.

The heating process during canning destroys from one-third to one-half of vitamins A and C, riboflavin, and thiamin. For every year the food is stored, canned food loses an additional 5 to 20% of these vitamins. However, the amounts of other vitamins are only slightly lower in canned food than in fresh food. Most produce will begin to lose some of its nutrients when harvested.
