SDCL § 34-18-36: Canned goods––Requirements.

No canned good may be sold unless the pH level is 4.6 or less or the water activity level is .85 or less.

Except as otherwise provided in this section, a producer selling canned goods under this section shall, every five years, complete food safety training approved by the department. The training must be available online. The producer shall retain records verifying the timely completion of such training.

A producer selling home-processed goods under this section may, in lieu of the requirement for food safety training, maintain verification of each recipe from a third-party processing authority. The third-party processing authority must have knowledge of the thermal processing required of food in hermetically-sealed containers and shall verify the method of processing and that the pH or water activity threshold levels are met. The processing authority shall provide verification in writing to the producer.
