What foods to avoid during the cyclosporiasis outbreak

by Adrienne Erin

You’re standing in the produce aisle, and suddenly every leafy green looks a little suspicious. That’s a reasonable reaction right now — cyclosporiasis cases have climbed past 6,000 nationwide, and health officials still haven’t pinned down a single confirmed source. Here’s what’s actually worth avoiding, what’s safe, and why.

Key Takeaways

  • No single food has been confirmed as the source of this year’s outbreak — but several foods have a track record from past Cyclospora outbreaks worth knowing about.
  • Cooking produce to 158°F kills the parasite completely, so cooked food is safe regardless of origin.
  • Peeled fruit and commercially frozen produce have never been linked to a Cyclospora outbreak.
  • Washing produce helps, but Cyclospora is unusually good at clinging to surfaces — thorough washing reduces risk, it doesn’t guarantee it.

Which Foods Have a History With This Parasite

Because investigators haven’t identified this year’s source, there’s no single ingredient to strike off your list. Instead, food safety experts are pointing to the foods that have caused Cyclospora outbreaks before, as a reasonable place to be extra careful:

  • Bagged lettuce and pre-mixed salad kits (including mesclun mixes, coleslaw, and vegetable trays)
  • Cilantro and parsley
  • Fresh basil
  • Raspberries — their bumpy surface makes them notoriously hard to wash clean
  • Snow peas and green onions

None of these are confirmed as this year’s culprit specifically — they’re foods with a history, not a verdict. A CDC deputy director noted that while cyclosporiasis outbreaks were historically tied to travel abroad, recent years have seen a rise in cases linked to both domestic and imported produce, which is part of why investigators are casting a wide net rather than clearing any one item.

Why These Particular Foods

It comes down to how the parasite spreads and what makes produce hard to fully clean. Cyclospora gets onto fruits and vegetables through soil or irrigation water contaminated with human feces, and it adheres to produce surfaces unusually well for a parasite. Foods that are eaten raw, have textured or porous surfaces (like raspberries or snow peas), or come pre-cut and bagged (where contamination has more chances to spread before it reaches you) are simply harder to fully decontaminate than something you’ll peel or cook.

What’s Actually Safe to Eat

This is the part that tends to get lost in outbreak coverage: plenty of produce remains entirely fine. Cooking any fruit or vegetable to an internal temperature of 158°F destroys the parasite completely — sautéed greens, roasted root vegetables, and anything else cooked through are not a risk. Peeled fruit is also in the clear; to date, no cyclosporiasis case has ever been linked to peeled fruit or commercially frozen produce, including frozen berries and vegetables. If you’re craving fiber from produce you’d normally eat raw, cooked or peeled options like potatoes, sweet potatoes, and yams are reasonable substitutes for now.

How to Lower Your Risk With Anything You Eat Raw

If you’re not ready to give up salads and fresh berries, the CDC’s standard advice still matters: wash your hands with soap and water before and after handling produce, wash all fruits and vegetables thoroughly under running water — even if labeled pre-washed — scrub firm produce like cucumbers and melons with a clean brush, and cut away any bruised or damaged spots before eating. None of this guarantees zero risk with a parasite this persistent, but it meaningfully reduces it.

When to See a Doctor

If you develop sudden, watery diarrhea — especially if it’s unusually frequent or severe — after eating raw produce in the past one to two weeks, it’s worth contacting a healthcare provider and specifically asking for a Cyclospora stool test, since it isn’t part of routine testing and the parasite doesn’t always show up on the first sample. The illness is treatable with a course of antibiotics, though it can drag on for weeks without treatment.
