Summer Food Safety Alert: Experts Warn of Parasitic Infections from Produce

As summer temperatures rise, health experts are issuing warnings about the increased risk of foodborne infections. Dr. Aslı Özer, an infectious diseases specialist, highlighted concerns beyond specific outbreaks like Cyclospora in lettuce, emphasizing the dangers associated with raw fruits and vegetables, pre-cut items sold openly, and iced beverages. Cyclospora, a parasitic infection, commonly spreads through contaminated water or food, and its risk escalates during warmer months when food safety practices may be compromised.

Salads prepared in establishments with inadequate hygiene conditions and ice from unreliable sources can create a breeding ground for microorganisms or their spread.

Dr. Özer specifically pointed to vegetables and fruits consumed raw, as well as sliced products not stored under proper conditions or sold outdoors, as high-risk items. "Salads prepared in establishments with inadequate hygiene conditions and ice from unreliable sources can create a breeding ground for microorganisms or their spread," she stated. For leafy greens like lettuce, she advised meticulous cleaning: "Before consuming lettuce, hands should first be cleaned, damaged or rotten leaves should be removed, and the leaves should be washed thoroughly under running clean water as much as possible, separating them from each other."

Özer stressed that the goal of washing is to reduce the microbial load, not eliminate it entirely, and cautioned against using soap, detergent, or bleach on produce. The advice extends to fruits with hard rinds, such as watermelons and melons. These should also be washed before cutting, as knives can transfer surface contaminants to the edible flesh. A gentle scrub with a vegetable brush can aid in cleaning hard surfaces.

The goal of washing is not to completely eliminate microorganisms, but to reduce the microbial load on the surface and thus the risk of infection.

Particular caution is urged for sliced fruits, especially those sold outdoors. Once a fruit is cut, its natural protective rind is compromised, making it susceptible to bacterial growth if not kept at appropriate temperatures. "Therefore, caution should be exercised against sliced fruits that have been left outdoors for a long time, especially in summer, under the sun or in conditions where the cold chain is uncertain. Cut fruits should be stored properly in the cold," Dr. Özer advised, noting that symptoms like vomiting and diarrhea can occur from such infections.
