Clean and slice mushrooms. Blanch or sauté before freezing. Pack in airtight freezer bags or containers, removing as much air as possible.

Room Temperature Safety
40°F–140°F
Perishable foods, including fresh shimeji mushrooms, should not be left at room temperature (between 40°F and 140°F) for more than 2 hours. If the ambient temperature is above 90°F (32°C), the limit is 1 hour.
Safe Handling
Wash hands thoroughly with soap and water before and after handling fresh produce.
Do not wash mushrooms until immediately before use to maintain freshness.
Avoid cross-contamination by keeping raw mushrooms separate from other foods, especially raw meats, poultry, and seafood.
Cook mushrooms thoroughly before consumption. While there is no specific internal temperature for mushrooms, ensure they are cooked until tender and fragrant.
