Berries naturally come into contact with these spores throughout their total lifecycle, from rising to reap to postharvest dealing with.
“Not like different fruits, berries should not washed earlier than being packed into clamshell containers attributable to their delicate nature, which implies fungal spores should not eliminated,” Kim explains.
Berries are stored as cool as attainable throughout transportation and storage to decelerate mould development—assume round 32°F (0°C), per Kim. However right here’s the place issues can take a flip for the more severe: “As soon as the fruit reaches retail shops, temperatures are sometimes raised to 40°F (4°C) or increased, particularly on retailer cabinets,” says Kim. “This temperature shift results in condensation contained in the clamshells, making a heat, humid surroundings—best circumstances for mould development.”
