Of many pathogens, the parasitic nematode of genus <jats:italic>Contracaecum<\/jats:italic>, which resides in the tissues of fish species, can results in fish\u2010borne infections in humans. This study was planned to assess consumers' awareness of fish\u2010borne zoonoses in the fishing sites of Lake Chamo, Arba Minch, Ethiopia. The study was also aimed at demonstrating the zoonotic nematode, <jats:italic>Contracaecum<\/jats:italic> parasites in the <jats:italic>Oreochromis niloticus<\/jats:italic> and <jats:italic>Lates niloticus<\/jats:italic> fishes collected from Lake Chamo, Arba Minch, Ethiopia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>Assessment of awareness about fish\u2010borne zoonoses was conducted in randomly selected participants (<jats:italic>n<\/jats:italic>\u2009=\u2009162) using face\u2010to\u2010face interviews via a structured and semi\u2010structured questionnaire. Besides, 70 fishes (<jats:italic>O.\u2009niloticus<\/jats:italic>\u2009=\u200935 and <jats:italic>L.\u2009niloticus<\/jats:italic>\u2009=\u200935) were examined for the presence of larva of <jats:italic>Contracaecum<\/jats:italic> and other anisakid genera through standard dissection, pepsin\u2010hydrochloric acid digestion and microscopic observation. Consumers have inadequate awareness about fish\u2010borne zoonoses based on the answers they provided to the questions. The majority of respondents (82%) consume raw fish in the area. Of these, a significantly higher proportion were male (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), completed their elementary or high school (<jats:italic>p<\/jats:italic>\u2009=\u20090.004), Orthodox Christian (<jats:italic>p<\/jats:italic>\u2009=\u20090.044), fishermen (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and participants without previous information about fish\u2010borne zoonoses (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Overall, of examined fishes (<jats:italic>n<\/jats:italic>\u2009=\u200970), <jats:italic>n<\/jats:italic>\u2009=\u200915 (21.4%, 95% CI, 12.8\u201333.2) were infected with <jats:italic>Contracaecum<\/jats:italic> larva. A significant (<jats:italic>p<\/jats:italic>\u2009=\u20090.028) higher infection prevalence was noted in <jats:italic>L.\u2009niloticus<\/jats:italic> (34.3%, 95% CI, 19.7\u201352.3) compared to <jats:italic>O.\u2009niloticus<\/jats:italic> (8.6%, 95% CI, 2.2\u201324.2). A unit gram addition in the total weight of fish would significantly raise the risk of <jats:italic>Contracaecum<\/jats:italic> infection by 1% (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The presence of <jats:italic>Contracaecum<\/jats:italic>, a zoonotic nematode in the fishes, which are often preferred by consumers for raw dishes, designates a high risk of possible fish\u2010borne infections in the area. Thus, providing education and training for fishermen, visitors of the area, and local people who visit the area for fish consumption, it is inevitably important to minimize the risk. Furthermore, health workers should suspect fish\u2010borne infections, such as anisakidosis in patients who have a history of raw fish consumption in Arba Minch, Ethiopia.<\/jats:p><\/jats:sec>","DOI":"10.1111\/zph.13145","type":"journal-article","created":{"date-parts":[[2024,5,21]],"date-time":"2024-05-21T04:20:15Z","timestamp":1716265215000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Awareness of fish\u2010borne zoonoses and prevalence of <i>Contracaecum<\/i> in <i>Oreochromis niloticus<\/i> and <i>Lates niloticus<\/i> collected from Lake Chamo, Arba Minch, Ethiopia"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2763-9088","authenticated-orcid":false,"given":"Tamirat","family":"Kaba","sequence":"first","affiliation":[{"name":"Veterinary Program, Department of Animal Science, College of Agricultural Science Arba Minch University  Arba Minch Ethiopia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mesfin","family":"Shurbe","sequence":"additional","affiliation":[{"name":"Livestock and Fishery Research Center, College of Agricultural Science Arba Minch University  Arba Minch Ethiopia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abreham","family":"Wondimu","sequence":"additional","affiliation":[{"name":"Livestock and Fishery Research Center, College of Agricultural Science Arba Minch University  Arba Minch Ethiopia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"issue":"2","key":"e_1_2_10_2_1","first-page":"1","article-title":"Prevalence of internal nematode parasites of Nile tilapia (Oreochromis niloticus) fish species caught from southwestern part of Lake Tana, Central Gondar, Ethiopia","volume":"11","author":"Abiyu M.","year":"2020","journal-title":"Journal of Aquaculture Research & Development"},{"key":"e_1_2_10_3_1","doi-asserted-by":"crossref","DOI":"10.1080\/23311916.2021.1979444","article-title":"Ethanol concentration and calorific value of some local distilled Ethiopian alcohol (Areki): An energy potential assessment","volume":"8","author":"Assaye A.","year":"2021","journal-title":"Cogent Engineering"},{"key":"e_1_2_10_4_1","doi-asserted-by":"crossref","DOI":"10.1016\/j.foodcont.2020.107724","article-title":"Quality issues related to the presence of the fish parasitic nematode Hysterothylacium aduncum in export shipments of fresh Northeast Arctic cod (Gadus morhua)","volume":"121","author":"Bao M.","year":"2021","journal-title":"Food Control"},{"key":"e_1_2_10_5_1","doi-asserted-by":"crossref","first-page":"38","DOI":"10.1016\/j.ijid.2017.08.012","article-title":"Human gastric hyperinfection by Anisakis simplex: A severe and unusual presentation and a brief review","volume":"64","author":"Baptista\u2010Fernandes T.","year":"2017","journal-title":"International Journal of Infectious Diseases"},{"key":"e_1_2_10_6_1","doi-asserted-by":"crossref","DOI":"10.1038\/s41598-022-17671-5","article-title":"Hygienic assessment of fish handling practices along production and supply chain and its public health implications in Central Oromia, Ethiopia","volume":"12","author":"Bedane T.
