Storing and applying compost under the Produce Safety Rule

The Produce Safety Rule proposes that storage of the final composted product be done in a manner that prevents a reintroduction of fresh animal derived materials. From the produce rule’s perspective, ensuring animals do not have access to compost piles and avoiding the mixing of piles of different ages are important to the integrity of the final product.

Applying compost can also be done in a manner that can reduce risk or enhance it. In general, if compost is applied in a manner that minimizes the potential for contact with the harvestable portion of the crop, it would be considered a lower risk than a broadcast application over the top of a crop. Aim to minimize direct contact of compost with the crop as much as practical.

If you have specific questions about food safety aspects of compost use or have difficulty tailoring good agricultural practices (GAPs) to your farm, contact the Michigan State University Extension Agrifood Safety Work Group at [email protected] or 517-788-4292.
