Health officials in Alberta have declared an outbreak of cryptosporidiosis at Butterfield Acres, a Calgary petting farm. As of this month, five confirmed cases have been identified among visitors.

What is Cryptosporidiosis?

Cryptosporidiosis is a highly contagious gastrointestinal illness caused by the Cryptosporidium parasite. The parasite spreads through contact with infected feces, thriving in the intestines of both animals and humans.

Symptoms and Risks

Symptoms typically appear within 2 to 10 days of exposure and include severe watery diarrhea, fever, nausea, vomiting, abdominal pain, and weight loss. Dehydration is a common complication, posing significant risks to immunocompromised individuals and young children.

Farm Response and Public Health Measures

Butterfield Acres, located on the northwestern outskirts of Calgary, has temporarily closed to mitigate risks. Public Health inspectors have visited the site, and remediation efforts are underway to sanitize affected areas and restrict access to potentially contaminated animals.

The farm has been cooperating with health authorities, disinfecting pens and enhancing hygiene protocols. Management confirmed a recently introduced calf tested positive for cryptosporidium and was euthanized, while its twin remains in quarantine.

Expert Commentary

Craig Jenne, a microbiology professor at the University of Calgary, emphasized the dangers for those with weakened immune systems. He noted that dehydration in infants can be life-threatening. While no hospitalizations or deaths have been reported, health officials urge symptomatic individuals to seek medical attention.

Preventative Measures

Health authorities advise frequent handwashing, avoiding food preparation for others while symptomatic, and staying home from work or school for 48 hours after symptoms cease. Visitors to petting zoos are reminded to wash hands thoroughly after animal contact and avoid touching their faces.

Provincial Surveillance

Alberta’s latest surveillance report indicates 171 cryptosporidiosis cases in 2024, highlighting the need for continued vigilance in public health measures. Experts anticipate further monitoring of wastewater and other potential contamination sites to prevent further spread.
