US Cyclosporiasis Cases Monitored; Mexico Denies Lettuce Outbreak Link After FDA Correction

US health authorities continue to track thousands of cyclosporiasis cases, an intestinal infection characterized by intense diarrhea. The Centers for Disease Control and Prevention (CDC) reported over 4,100 infections nationwide, prompting concern and speculation on social media about a potential link to Mexican lettuce.

Although versions emerged on social media about a supposed outbreak in Mexico linked to Mexican lettuce, the Ministry of Health clarified the situation in the country.

However, Mexico's Health Ministry has clarified the situation within the country. Secretary of Health David Kershenobich stated that only three cases have been identified in Mexico, and epidemiological surveillance is ongoing without indicating a national outbreak comparable to the US situation.

Further complicating the issue, the US Food and Drug Administration (FDA) revised an initial report concerning a lettuce sample from Guanajuato, Mexico. Kershenobich explained that a preliminary positive test was later determined to be a false positive by the FDA. Consequently, there is currently no evidence connecting this specific product to the outbreak in the United States.

The official reported that, so far, only three cases have been identified in Mexico, so authorities maintain epidemiological surveillance without considering that there is a situation similar to the one registered in the United States.

Despite the lack of a confirmed outbreak in Mexico, health officials emphasize the importance of proper food hygiene to mitigate the risk of cyclosporiasis and other foodborne illnesses. Recommendations include thoroughly rinsing leafy greens like lettuce and spinach under running potable water to remove dirt and microorganisms. Additionally, washing hands with soap and water for at least 20 seconds before handling food and disinfecting preparation surfaces and utensils are advised.

Initially a test turned out positive, but later the FDA determined that it was a false positive, so currently there is no evidence linking that product to the outbreak.
