Farmers Fresh Mushrooms (formerly Premier Mushrooms) is one of Colusa County’s largest private‑sector agricultural employers and a leading innovator in mushroom production. The company acquired Premier Mushrooms in 2019 and continues its rapid growth within the Colusa Industrial Park.

The farm has expanded from 16 to 64 advanced grow rooms, increasing production from 70,000 lbs. to nearly 300,000 lbs. per week. Today, the facility includes 260,000+ sq. ft. of growing space and is recognized as one of the most technologically advanced mushroom farms in the country.

Farmers Fresh operates a full‑cycle production system where mushrooms are composted, grown, harvested, processed, and distributed on‑site. Composting and pasteurization take place in a fully enclosed wharf, improving quality and reducing environmental impact.

Each grow room features automated climate‑control technology regulating temperature, humidity, and CO₂. Rooms are steam‑sterilized between cycles to minimize chemical use, and aluminum grow beds help prevent bacterial growth. Barcoded traceability allows every box to be tracked back to the picker, room, and vendor.

Farmers Fresh is committed to sustainability, land stewardship, and community education, supporting youth programs and promoting local food systems. The company continues to invest in environmentally responsible practices while serving as a strong economic partner in the Colusa Valley.
