False morels must be accompanied by warning and handling instructions
False morels are an exceptional food whose sale is permitted although they contain a naturally occurring toxin called gyromitrin. A large dose of gyromitrin causes acute poisoning. Gyromitrin and its metabolites are also carcinogenic compounds. Proper handling is required to avoid poisoning, and consumers in Finland are reminded of this each year.
Foreigners living in Finland may not be aware that false morels are poisonous or may not know how they should be handled.
If instructions for handling false morels are not displayed at sales points, control officials can forbid the sale of lots which do not comply with regulations. Products can be put back on sale after the necessary warnings have been added. Consumers can also notify municipal food control officials if labels are inadequate.
Evira has published brochures on the handling of false morels in Finnish, Swedish, English, German, French and Russian. The brochures can be obtained from municipal food control authorities and from Evira for display at sales points or for other information purposes.
Brochures can be ordered from Evira by e-mail at tilauksetevira.fi, or by telephone 020 77 25104 or 020 77 24062, or by fax 020 77 24350. Online ordering is also possible at: http://www.evira.fi/portal/fi/evira/julkaisut/. The brochures are free of charge, but postage is charged on orders of more than 100 copies or more than 2 kg in weight.
Instructions for handling false morels
Boiling: False morels should be boiled twice in plenty of water (1 part mushrooms and 3 parts water) for at least five minutes and should be rinsed thoroughly in plenty of water after each boiling.
Drying: False morels can also be preserved by drying them until they are crisp. Dried false morels must be soaked for at least two hours before use (100 grams of mushrooms in 2 litres of water). After soaking they should be boiled and rinsed twice like fresh false morels.
Remember: Ensure proper ventilation whenever false morels are boiled or dried. Do not reuse the water in which false morels have been soaked or boiled.
