EEIP RIDRM Trichinellosis
Trichinellosis is a gastrointestinal illness caused by the microscopic parasite Trichinella. Infection can occur by eating raw or undercooked meat from infected animals. Symptoms can range from very mild to severe, and in rare occasions can cause death. For mild to moderate infections, most symptoms will go away within a few months. Treatment is available and should begin as soon as possible.

Reporting Requirements - Category 2
Trichinellosis is physician reportable by mail within 12 hours of recognition or strong suspicion to both the Connecticut Department of Public Health (DPH) and the local health department (LHD). The director of any clinical laboratory must also report laboratory evidence of Trichinella to both the DPH and the LHD.

National Surveillance Case Definitions
Case Investigation
LHD Responsibility: If a cluster/outbreak is identified, the LHD will work with the DPH to implement control measures. They will also provide information and educational materials describing the nature of the disease and preventive measures.
DPH Responsibility: The DPH will contact the testing laboratory and the patient’s physician to confirm the diagnosis of trichinosis; interview the patient to collect food history during incubation period (5 – 45 days before symptom onset); specifically inquire about consumption of pork and pork products, other high-risk foods such as wild game meat and dried jerky, and methods of preparation; assess other household members and persons who have eaten suspected meat (if any) for evidence of infection; confiscate any remaining suspect food and consult with CDC about testing.
