About Us / Hazel Dell Mushrooms History: Hazel Dell's diverse mushrooms are organically grown according to USDA National Organic Standards and inspected annually by Colorado Department of Agriculture. Hazel Dell utilizes hardwood sawdust, wheat bran, rice bran, gypsum, and limestone to prepare the mixture that the mushrooms grow in. This mixture is steam sterilized in a special mushroom growing bag to avoid any bacterial or mold contaminants. All of mushroom culture lab work is performed in a super HEPA filtered clean room to minimize contamination after the sawdust bags are sterilized. Hazel Dell's employees even shower and change into sterile lab clothing before the innoculation process. Hazel Dell keeps harvest rooms clean and crop cycles short to avoid pest problems and eliminate the need to use pesticides.
