We're expanding with a new 28,000sqft warehouse/distribution center.

Quality Assurance

Premier Mushrooms' pride's itself on it's high standards to ensure you receive high quality, tasty mushrooms. Here are some of the ways we meet those standards:

  • After harvest, mushrooms are sent to our distribution center where they are graded for size and quality.
  • All bulk mushrooms are re-inspected by our warehouse and quality control team
  • Mushrooms are only touched by workers when they are picked (to avoid bruising)
  • Once packed mushrooms are put through a "blast" chiller to reach an ideal temperature before shipping. Maintaining a proper temperature of 34 to 38 degrees maximizes shelf life and quality.

Food Safety

Premier Mushrooms holds the Gold Standard for food safety. We strictly adhere to the rigorous guidelines of the American Mushroom Institute and its Mushroom Growing Practices program along with USDA regulations and the international standards set by the Hazard Analysis Critical Control Points.

To ensure that our mushrooms are completely safe for consumption, every step of our production is meticulously clean and safe. After each grow-cycle steam is utilized to sterilize the rooms in order to ensure maximum quality and safety while minimizing the use of chemicals. All of our workers are equipped with sanitized clothing, hair nets and rubber gloves.

We also undergo an annual food safety audit by Primus Labs which entails a micro- analysis of water sources, the environment, our production and the final product.
