To stay safe, always cook mushrooms thoroughly.

Storing Spores: Safe Practices

Proper storage keeps mushrooms safe to eat. Keep Portobellos in the fridge, not on the counter. Use them within a few days of buying. Look for these signs of spoilage:

Storing mushrooms in a paper bag can keep them dry and extend their life. A plastic wrap traps moisture and promotes bacteria growth. Be mindful of these tips to enjoy Portobellos safely!
