This is CDC’s final update to this food safety alert. At this time, there is no risk of people getting sick with cyclosporiasis from this source. The best-by dates for all product linked to this outbreak have passed and it is no longer available in stores or restaurants.
In addition, CDC has seen a significant decrease in recent infections linked to this outbreak. At the peak of the outbreak, before the recall, more than 1,000 infections occurred in a single day. Fewer than 2 infections per day on average occurred in August.
FDA continues to investigate how the product linked to this multistate outbreak became contaminated with Cyclospora. FDA may post updates to their website while their investigation continues.
What you should do
- Wash your hands and any fresh produce thoroughly under running water before eating, cutting, or cooking.
- Cooking can kill the parasite. Since washing alone cannot guarantee Cyclospora removal, you can cook produce to a temperature of at least 158 °F (70°C).
- Learn which foods are more likely to contain the parasite Cyclospora and ways to prevent getting cyclosporiasis.
- Stay up to date on food recalls and outbreaks.
