The American Mushroom Institute has announced that market challenges such as global supply chain issues, transportation constraints, crop diseases, and a reduced labor market are causing a significant decrease in U.S. mushroom production. These challenges, along with a lack of key ingredients for the growing medium and competition for growing space, have resulted in a forecast of a greatly reduced mushroom holiday supply. The industry is currently operating with about 75% of the necessary labor force, further exacerbating the problem.
