Mold on Mushrooms: Contamination Tips For Shroom Growers

“Every mushroom grower at some point experiences the disappointment of moldy mushrooms. Even in professional environments, mushroom growers will occasionally have problems—for instance, when someone is careless, working when tired, or takes a shortcut and then two weeks later the spawn, or casing layer, is blue-green! The important thing to realize is: It happens! Try to identify the source of the contamination if you can, and try again.

All mushroom businesses have strategies to mitigate contamination, knowing that it is likely to occur and creating steps to minimize outbreaks when it does. That includes having a plan to contain and control contamination with log books, tracking which inoculant was used for which grow, and appropriately labeling syringes, jars, and containers.”
