Abstract
Recently, an outbreak of human toxoplasmosis was identified in Santa Maria city, Southern Brazil. However, the suspected vehicle of Toxoplasma gondii contamination in this region remains unclear. This study was conduct to analyze whether pork meat samples collected in supermarkets from Santa Maria city, RS, could be infected with T. gondii. Thus, we analyzed the presence of T. gondii DNA in 20 pork hearts, 20 pork tongues and 20 sausages. DNA was extracted from each sample and real-time PCR was performed using 529-bp and B1 markers. T. gondii genotyping was performed by PCR-RFLP analysis. T. gondii DNA was detected in 2 of 20 (10%) heart samples andin 1 of 20 (5%) tongue samples using 529-bp marker. Besides, those 2 (10%) heart samples also were positive for T. gondii using B1 marker. All sausage samples were negative for both markers. Genotyping revealed a new atypical genotype in the pork meat. Our findings were not able to confirm whether these food samples were involved in some outbreak. However, we can conclude that food samples containing T. gondii can be displayed in Santa Maria supermarkets. In addition, a new T. gondii genotype was identified circulating in southern Brazil.
