These analyses were detection of WNV IgM by ELISA using the WNV IgM Capture DxSelect (Focus Diagnostics, ) at the LSPQ detection of Brucella spp. Cutoff values used to interpret the results were those recommended by the manufacturers. gondii IgG was detected, we analyzed serum samples by using the Vidas Toxo IgG Avidity Assay (bioMérieux). gondii IgG and IgM by using VIDAS TOXO IgM and IgG II assays (bioMérieux, ). We tested symptomatic and asymptomatic hunters by using serologic analysis for toxoplasmosis, brucellosis, leptospirosis, Q fever, hepatitis E, West Nile virus (WNV), and Lyme disease. Attendees were interviewed mostly by public health nurses or medical microbiologists and infectious disease physicians. For persons who had symptoms, we obtained information on onset dates and symptoms. The following information was collected from each attendee, symptomatic or asymptomatic: demographic information description of activities at the outfitter, including deer hunting and evisceration food consumed on site, including deer meat and how it was eaten (raw, undercooked, or well done) consumption of water and possible exposure to ticks or other animals. This investigation was conducted in collaboration with the Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Quebec (MAPAQ: Ministry of Agriculture, Fisheries, and Food of Quebec), public health units, and the Laboratoire de Santé Publique du Quebec (LSPQ: Public Health Laboratory in Quebec).Īll 10 hunting companions who attended the retreat in Illinois were interviewed. On December 20, 2018, the Direction de la Vigie Sanitaire at the Ministère de la Santé et des Services Sociaux (Ministry of Health in Quebec) initiated an investigation. We conducted an investigation to determine the outbreak magnitude, describe illness-related factors, and coordinate Toxoplasma spp. We report an acute toxoplasmosis outbreak in Quebec, Canada, associated with consumption of venison. However, it is quite rare to observe a cluster of cases related to undercooked deer meat, particularly related to consumption of venison. A recent outbreak was reported in the United States during 2017 ( 15). Toxoplasmosis infection was documented in 1 Alabama and 2 South Carolina deer hunters during 1980 ( 14). Cases of clinical toxoplasmosis have been documented in humans who had consumed undercooked venison ( 13). However, outbreaks of acute toxoplasmosis seem to be rare.Ĭervids can be infected by T. Reactivation of the disease is possible sometimes years later. Lymphadenopathy, frequently cervical, is the most common sign ( 3). When symptoms develop, they are nonspecific and include malaise, fever, headache, sore throat, arthralgia, and myalgia. Symptoms appear mostly in immunocompromised persons. gondii infection acquired after birth can be asymptomatic in humans. Frequency of human infection might vary substantially by region because of ecologic, social, and cultural factors ( 3). gondii infection is caused by ingestion of tissue cysts in undercooked meat ingestion of soil, water, or food contaminated with oocysts or, less frequently, directly from feline feces ( 3 – 8). Felids are essential to the epidemiology of this parasite ( 2). gondii, meaning they are the only animals in which replication can result in the production of oocysts (eggs), which are then shed in the feces ( 2, 3). It can infect virtually all warm-blooded animals, including birds, livestock, marine mammals, and humans ( 2). Toxoplasma gondii is one of the most common zoonotic parasites and can cause serious illness in humans and other animals worldwide ( 1 – 3).
