A foodborne illness outbreak caused by the Cyclospora parasite has spread, with reports now indicating it has affected at least nine states and sickened more than 1,900 people. Health officials have linked the outbreak to iceberg lettuce. The Centers for Disease Control and Prevention and the Food and Drug Administration are investigating the source of the contamination. In response to the outbreak, a former director of the FDA's food safety and nutrition center emphasized that consumers should not have to choose between eating nutritious foods and ensuring their safety. The official urged that food safety measures must keep pace with the demand for fresh produce. Consumers are advised to check for recalls and to wash lettuce thoroughly, though cooking may be the only way to kill the parasite. Symptoms of Cyclospora infection include watery diarrhea, stomach cramps, and nausea, which can last for weeks if untreated. Health authorities continue to monitor the situation and provide updates as the investigation progresses.
