Food claiming to have ‘wild mushrooms’ rarely does
Harvesting wild mushrooms requires an expert eye, making products containing wild fungi expensive. Due to minimal food regulations, it’s nearly impossible to know what species are actually contained within. Sequencing revealed food products labeled with wild mushrooms mostly contained cultivated fungi and some mushrooms poisonous to humans.
