Among the various species intended for human consumption, sheep appear to be a high risk for human infection. The present study focused on the detailed anatomical distribution of <jats:italic>Toxoplasma gondii<\/jats:italic> in naturally and experimentally infected lambs using fresh and frozen samples of various pieces of meat, from a public health perspective. The first objective was to rank the edible parts intended for human consumption according to the detectable parasite burden by real-time PCR targeting the 529-bp repeated element. The second objective was to evaluate the impact of freezing by comparing the detection efficiency of the quantitative PCR between fresh and frozen tissues, as imports of lamb carcasses\/cuts may arrive frozen or chilled. The highest estimated parasite loads were observed in skeletal muscles, and more particularly in edible portions such as quadriceps femoris muscle, intercostal muscles, deltoid muscle and diaphragm, with a significant difference in detectable parasite burden between fresh and frozen samples (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.0001) or natural and experimental infection (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.0001). Thoracic and pelvic limbs (3278\u20131048 parasites\/g muscle) were ranked at the top of the list. <jats:italic>Toxoplasma gondii<\/jats:italic> DNA was detected in all the edible parts of lamb studied. These results suggest that lamb meat represents a risk for consumers. Further investigations are needed in order to confirm these differences in larger numbers of animals and in different breeds.<\/jats:p>","DOI":"10.1051\/parasite\/2022001","type":"journal-article","created":{"date-parts":[[2022,2,1]],"date-time":"2022-02-01T08:58:15Z","timestamp":1643705895000},"page":"3","source":"Crossref","is-referenced-by-count":13,"title":["Anatomical distribution of <i>Toxoplasma gondii<\/i> in naturally and experimentally infected lambs"],"prefix":"10.1051","volume":"29","author":[{"given":"Myriam","family":"Thomas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominique","family":"Aubert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandie","family":"Escotte-Binet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beno\u00eet","family":"Durand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9line","family":"Robert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00e9gine","family":"Geers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annie","family":"Alliot","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Belbis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Villena","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Radu","family":"Blaga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2022,2,1]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1080\/00365549950163626","volume":"31","author":"Baril","year":"1999","journal-title":"Scandinavian Journal of Infectious Diseases"},{"key":"R2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.18637\/jss.v067.i01","volume":"67","author":"Bates","year":"2015","journal-title":"Journal of Statistical Software"},{"key":"R3","doi-asserted-by":"crossref","first-page":"e0153856","DOI":"10.1371\/journal.pone.0153856","volume":"11","author":"Belluco","year":"2016","journal-title":"PLoS One"},{"key":"R4","doi-asserted-by":"crossref","first-page":"3085","DOI":"10.1080\/10408398.2017.1352563","volume":"58","author":"Belluco","year":"2018","journal-title":"Critical Reviews in Food Science and Nutrition"},{"key":"R5","doi-asserted-by":"crossref","first-page":"472","DOI":"10.1111\/j.1863-2378.2011.01395.x","volume":"58","author":"Berger-Schoch","year":"2011","journal-title":"Zoonoses and Public Health"},{"key":"R6","unstructured":"FAO\/WHO [Food and Agriculture Organization of the United Nations\/World Health Organization]. 2014.
