CAMPO-PORTACIO, Diana Marcela et al. Toxoplasma gondii detection by gene B1 amplification in meat human consumption . Infect. [online]. 2014, vol.18, n.3, pp.93-99. ISSN 0123-9392.

Objective: To determine the frequency of infection by Toxoplasma gondii in different types of meat that is sold for human consumption in Sincelejo-Sucre, by PCR for B1 gene amplification. Materials and methods: A total of 120 samples of meat for human consumption were obtained at 2 types of outlets (municipality public market and retail chain stores) in the city of Sincelejo. At each store, 60 samples of 3 different species were obtained: 20 beef samples, 20 pork samples and 20 chicken samples. These samples were submitted to DNA extraction procedures for tissues and to nested PCR to amplify B1 specific genomic region of T. gondii. Results: Toxoplasma gondii DNA was detected in 32% of the analyzed meat. There were a slight higher frequency (36,6%) in samples collected at the municipality public market compared to retailed chain stores (26,7%) without statistical significance. The frequency of infection was similar between animal species: chicken (35%), pork (32,5%) and beef (27,5%). Conclusions: This work demonstrates a high frequency of T. gondii infection in different types of meat sold for human consumption in the town of Sincelejo, suggesting a high risk of infection by the parasite in the population.
