Health expert warns of foodborne infection risks from lettuce and ice

Infectious disease specialist Dr. Aslı Özer of the Medicana Health Group has issued warnings regarding food safety risks during the summer months, specifically concerning Cyclospora, a parasitic infection. The warnings follow investigations in the United States into Cyclospora cases linked to certain chopped iceberg lettuce.

Dr. Özer noted that high summer temperatures increase the risk of foodborne infections. She highlighted that raw vegetables and fruits, sliced products left uncovered, and ice from unreliable sources can facilitate the spread of microorganisms. Specifically, lettuce and other leafy greens can be contaminated through soil, irrigation water, animals, or improper handling during preparation.

To mitigate risks, Dr. Özer recommends washing leafy greens by separating the leaves and rinsing them thoroughly under running water, paying close attention to curves and contact surfaces. She also advised that watermelon and melon should be washed before being cut to prevent surface microorganisms from transferring to the flesh. Notably, she cautioned against using soap, detergents, or bleach to clean produce.
