Human Feces on Produce? Cyclospora Outbreak Sparks Alarm
18 Jul
Summary
- US outbreak of cyclospora linked to imported iceberg lettuce from Mexico.
- Researcher questions farm conditions and fertilizer use involving human waste.
- Experts caution multiple food sources could be responsible for illnesses.

A concerning outbreak of cyclospora, a parasite leading to significant gastrointestinal distress, has been identified across the United States. Federal health officials have established a connection between the illnesses and iceberg lettuce imported from Mexico. However, health experts caution that this may not be the sole source of contamination.
Concerns have been raised about agricultural practices in other countries, including the potential use of human waste, or 'humanure,' as fertilizer. This practice is reportedly more common in regions facing increased fertilizer prices. While the U.S. Environmental Protection Agency permits the use of treated sewage sludge, known as biosolids, for soil conditioning and fertilization, the safety and oversight of foreign farming methods remain a critical question.
Experts emphasize the need for greater transparency and monitoring of how produce is cultivated internationally. The ongoing investigation aims to identify all contributing food sources to prevent further spread of the cyclospora parasite and protect public health.
