Eating undercooked meat of infected animals has been considered the major transmission route of T. gondii to humans. The present study was conducted to evaluate the efficacy of domestic freezing for inactivation of T. gondii bradyzoites in ham. Raw and dry-cured ham from a pig experimentally inoculated orally with 4,000 oocysts of T. gondii VEG strain was subjected to domestic freezing at −20°C for up to 14 days. The effect was evaluated by bioassay in mice and a quantitative PCR assay. In raw and dry-cured ham, −20°C for 7 and 14 days, respectively, did not inactivate T. gondii. More studies are needed to find the correct temperature and time needed to render the bradyzoites noninfectious for humans. Meanwhile, the recommendations for freezing to inactivate T. gondii in raw or dry-cured meats must be revisited because domestic freezing conditions do not reduce the risk of infection. 000134824 536__ $$9info:eu-repo/grantAgreement/ES/DGA/A06-20R$$9info:eu-repo/grantAgreement/ES/INIA/RTA2014-00024-C04-02 000134824 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000134824 590__ $$a2.0$$b2022 000134824 591__ $$aFOOD SCIENCE & TECHNOLOGY$$b104 / 142 = 0.732$$c2022$$dQ3$$eT3 000134824 591__ $$aBIOTECHNOLOGY & APPLIED MICROBIOLOGY$$b124 / 158 = 0.785$$c2022$$dQ4$$eT3 000134824 592__ $$a0.47$$b2022 000134824 593__ $$aFood Science$$c2022$$dQ2 000134824 593__ $$aMicrobiology$$c2022$$dQ3 000134824 594__ $$a4.2$$b2022 000134824 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000134824 700__ $$0(orcid)0000-0002-6460-1388$$aLázaro, Regina$$uUniversidad de Zaragoza 000134824 700__ $$0(orcid)0000-0003-2247-0954$$aPérez-Arquillue, Consuelo 000134824 700__ $$0(orcid)0000-0002-1668-4940$$aBayarri, Susana$$uUniversidad de Zaragoza 000134824 7102_ $$12008$$2640$$aUniversidad de Zaragoza$$bDpto.
