Frequently Asked Questions

Who must be licensed?
A person or legal entity shall not sell, label, describe, advertise, offer, expose, exchange, or transport fruits or vegetables for sale represented as having been held under controlled atmosphere storage conditions as specified in the act, unless the sealed storage rooms are licensed.

  • If you use the term “CA” or Controlled Atmosphere on containers, they must come from a licensed controlled atmosphere storage room.
  • Several states and foreign countries have quarantines that require apples and other fruit to be held in licensed and approved CA storage in order to qualify for phytosanitary certification. If your firm is not licensed as a CA facility, it cannot be approved for plant pest regulatory purposes. If your firm exports products to a state or country that has special requirements such as continuous monitoring, please contact Mike Bryan at 517-284-5648 to ensure your firm meets these special requirements.
