The recent storms and warm weather have encouraged the growth of mushrooms throughout the Valley’s vineyards. Most of the mushrooms can be identified as morels (Morchella esculenta), a well known and sought after mushroom by chefs and food enthusiast. The past few years mushroom harvesters have descended on valley vineyards, filling five gallon buckets with mushrooms for personal and commercial consumption. Although morels are quite tasty, harvesters should think twice about collecting and eating mushrooms from vineyards. Several San Joaquin Valley County Ag Commissioners have released public notices that warn mushroom harvesters that they could be breaking several laws and putting themselves and others at risk when these mushrooms are consumed. Below are some of the points that should be shared and considered by the harvesters and general public.
- Pesticides have been applied during the dormant season including pre-emergent herbicides and could leave a residue on the mushrooms, causing illness.
- Some species of morels can only be eaten after being cooked.
- Some mushrooms look like morels--"false morels"--and are highly toxic to humans.
- Vineyards and other crop land is private property and trespassing is forbidden. Concerned growers should contact the Sheriff's Department to report suspicious activity.
- Selling harvested mushrooms or moving them through commercial channels of trade is against the law.
For additional information contact your local Ag Commissioner.
