Why this matters in The San Antonio

San Antonio residents who frequent Taco Bell restaurants or consume shredded lettuce should be aware of the expanding outbreak of cyclospora, a diarrhea-causing parasite. With the CDC now linking cases to nine states, including neighboring Oklahoma, the risk of local exposure increases. Bexar County health officials should be vigilant in monitoring reports of intestinal illness and tracing potential sources of contaminated lettuce. The fact that Taylor Farms, the suspected source of the outbreak, recalled iceberg lettuce grown in central Mexico raises questions about the safety of produce imported from Mexico. As the investigation continues, San Antonio consumers should take precautions when eating at restaurants or buying lettuce from local retailers, and health officials should be prepared to respond quickly if cases are reported in the area. The CDC's warning that other brands, restaurants, or retailers could be tied to the outbreak underscores the need for continued vigilance in San Antonio.
