‘Explosive diarrhoea’ outbreak grips US: how researchers are hunting its source

TL;DR - A Nature news article reporting that US cases of Cyclospora-linked "explosive diarrhoea" have reached record levels, with researchers racing to trace where the parasite entered the food supply. It matters as a public-health and food-safety investigation, though it has no direct AI component.

• Content is thin (title plus a one-line blurb), so takeaways are limited to what is stated.
• Reports a record-level US outbreak of gastrointestinal illness attributed to the Cyclospora parasite.
• Scientists are actively investigating to pinpoint the food-supply contamination source.
• This is Nature journalism (a d41586 news piece), not a peer-reviewed study, so it's classified as Industry & News rather than Research; no AI methods or results are described.
