Potential Dairy Producers memo
PMO Selection for Dairy Producers
If you are simply selling excess eggs from your backyard flock to friends and neighbors, directly from your farm or home -- good news - no license is needed! If, however, you want to sell your eggs where they will be resold at retail (i.e. a grocery store, cafe, etc.) or if you are selling more than 25 cases (30 dozen/case) a month, then you need to get an egg grading license. All the information you need to obtain your license is found in the documents below, including the equipment you will need. When you are ready to be tested to get your license, contact the State Sanitarian for your area, who can be found here: Sanitarian District Map
As always, your Sanitarian will be available to help you through the process and ensure all requirements are met prior to licensing.
