- The FDA found a strong epidemiological and traceback link between the outbreak and recalled shredded iceberg lettuce produced by Taylor Farms in Mexico, but there was insufficient evidence to determine how contamination occurred.
- The agency reported two environmental samples positive for cyclospora in Mexico: one from wastewater leaving a processing facility and another from a drainage ditch at an iceberg lettuce farm.
- Mexico's food-safety regulator Cofepris reported that tests by its national reference laboratory on raw materials, finished products and water from the facility investigated were negative for the cyclospora parasite.
- Mexico's Health Ministry said that a US Food and Drug Administration (FDA) investigation into the cyclospora parasite outbreak linked to shredded iceberg lettuce from Taylor Farms in Mexico did not conclusively identify the source of contamination.
- The Centers for Disease Control and Prevention (CDC) declared the outbreak over on September 11. The outbreak sickened 12,883 people in 21 states, hospitalized 570, and was linked to two deaths.
- The regulator added that environmental findings alone do not constitute conclusive evidence that agricultural products were the source of contamination.
- Mexico said it cooperated throughout the investigation, providing traceability information, inspections and samples, and would continue technical cooperation with US health authorities.
Mexico's Health Ministry announced that the FDA's investigation into the cyclospora outbreak linked to Taylor Farms' shredded iceberg lettuce did not conclusively identify the source of contamination. The investigation revealed a strong epidemiological link to the lettuce, but evidence was insufficient to determine how the contamination occurred.
The FDA reported two environmental samples positive for cyclospora, one from wastewater leaving a processing facility and another from a drainage ditch at an iceberg lettuce farm. However, Cofepris, Mexico's food-safety regulator, stated that tests on raw materials, finished products, and water from the facility were negative for the parasite. They emphasized that environmental findings alone do not provide conclusive evidence of contamination from agricultural products.
The CDC declared the outbreak over on September 11, after it sickened 12,883 people across 21 states, leading to 570 hospitalizations and two deaths. Mexico confirmed its cooperation throughout the investigation, providing traceability information, inspections, and samples, and pledged to continue technical cooperation with US health authorities.
“Cofepris tests on raw materials, finished products, and water were negative, but two environmental samples—wastewater and a drainage ditch—tested positive. The outbreak sickened 12,883 people across 21 states, with 570 hospitalizations and two deaths.”
