For instance, some suppliers in the United States do in-house growing of shiitake mushrooms using only domestically sourced ingredients; they do not employ GMOs, pesticides, or any harmful chemicals. These suppliers are committed to eco-friendly farming practices, using compost made from plants and solar energy. These organic shiitake mushroom suppliers offer mushrooms as whole, half, or petite sizes and package them in clamshells along with other sophisticated packaging options, ensuring they can sell to retailers, distributors, and food service organizations.
