Public health officials are reporting the investigation into the Giardia outbreak in Hopkins County has now expanded after cases have been identified in Muhlenberg and Webster counties.
According to a statement released Monday, the Kentucky Department for Public Health, the Hopkins County Health Department, and the Centers for Disease Control and Prevention are investigating a Giardia outbreak primarily centered in Hopkins County. Since May, officials have reported 66 laboratory-confirmed cases across Hopkins, Muhlenberg, and Webster counties.
While the exact source of the infections remains unclear, health officials said many of the individuals affected reported dining at El Tapatio Mexican Cantina in Madisonville. Health officials emphasized that the restaurant has fully cooperated with the ongoing investigation, and environmental sampling continues as authorities work to pinpoint possible sources of Giardia exposure.
Giardia is a parasite found in untreated water like streams, rivers, and lakes, and it spreads easily through contaminated water, food, or other surfaces. Symptoms—such as diarrhea, gas, nausea, stomach pain, and fatigue—usually appear one to three weeks after exposure and may last for several weeks. Young children, pregnant women, and those with weakened immune systems face a higher risk for dehydration or other complications.
According to public health officials, Kentucky has about 100 to 300 cases of Giardia reported each year, most often during summer and early fall and frequently linked to swimming in lakes, rivers, or pools. Those experiencing symptoms should consult a healthcare provider. People with diarrhea should avoid food service, healthcare work, daycare, or recreational water activities until they have fully recovered.
