CANTU-MARTINEZ, Marco Antonio et al. Molecular detection of hepatitis E virus in pig livers destined for human consumption in the state of Nuevo Leon, Mexico. Salud pública Méx [online]. 2013, vol.55, n.2, pp.193-195. ISSN 0036-3634.

OBJECTIVE: Molecular detection of HEV in pig livers destined for human consumption in Nuevo Leon, Mexico. MATERIALS AND METHODS: 87 livers were collected from pigs slaughtered in TIF and 40 livers from butchers. A 212 pb fragment of HEV ORF2 gene was amplified by semi-nested RT-PCR. RESULTS: 19.54% (17) of tif's and 22.5% (9) of buthcer's livers were positive for HEV. Sequencing of the amplified products showed a 94%-95% homology with the sequences reported for genotype 3. CONCLUSIONS: Our results indicate that HEV is circulating in swine herds in the state, constituting a probable source of contamination of pig meat products.
