New Hampshire officials investigate cyclospora outbreak linked to lettuce

New Hampshire health authorities are investigating a cyclospora outbreak connected to lettuce consumption at Cheshire Medical Center in Keene.

Outbreak investigation underway

Health officials in New Hampshire have launched an investigation into a cluster of cyclospora infections. Preliminary data indicates a link between the illnesses and the consumption of lettuce served at Cheshire Medical Center.

Cyclospora is a microscopic parasite that causes gastrointestinal illness. Common symptoms include watery diarrhoea, bloating, gas, nausea, and abdominal cramping. The investigation aims to identify the specific source of the contaminated produce to prevent further transmission.

Public health response

Local health departments are working alongside state officials to track the scope of the outbreak. This process involves interviewing affected individuals to establish a precise timeline of food consumption and symptom onset.

While the investigation continues, health experts advise the following precautions for those who may have eaten at the facility:

  • Monitor for gastrointestinal symptoms such as severe stomach cramps or nausea.
  • Consult a medical professional if symptoms persist or become severe.
  • Report any suspected foodborne illnesses to local health authorities.

Authorities have not yet released specific details regarding the brand or origin of the lettuce involved. Further updates are expected as laboratory testing and contact tracing efforts yield more conclusive results regarding the contaminated batches.
