Why do berries go bad so fast? It comes down to moisture… and mold. Berries tend to be quite porous, water-rich and delicately skinned, meaning they soak up excess moisture in their environment very easily. They also pretty much all carry mold spores, which grow rapidly when moisture is plentiful.
Symptoms may develop rapidly (2 to 4 days) when fruit is stored at room temperature. A common postharvest rot of blueberries in Michigan, characterized by greenish gray mycelium and dark olive-green spores. Fungal growth often starts at the stem scar and can completely engulf the berry.
