Background In recent decades, the celiac disease showed a gradual increase in prevalence. Therefore, there was a raised demand of gluten-free products. EU Reg. 1169/2011 states that 20 mg.kg-1 (ppm) is the maximum gluten content in food for celiac people, and that “gluten-free” labelling must be put on compliant food packages. This work is a study...

Mammalian orthoreovirus (MRV) and Torque teno sus virus (TTSuV) are emerging infectious viruses, with likely zoonotic potential, that may affect both domestic and wild animals. MRV is a dsRNA virus that can cause respiratory, central nervous system, and enteric diseases both in human and in other mammalian hosts. TTSuV is a DNA virus that frequentl...

SUMMARY Hepatitis E virus (HEV) is an emerging virus with an increasing diffusion across Europe. Because of the apparent lack of species barriers, HEV was characterized as a zoonotic agent, with swine as main reservoir, but it has been also found in wild animals. This study aimed to assess the HEV prevalence in wild boars, hares and swine in an are...

Norovirus is an enteric virus with foodborne transmission. Bivalve shellfish are a main source of infections and outbreaks, which in the last years showed an increasing trend. Therefore a monitoring plan was set up to control the NoV prevalence in this food category considered at high risk of contamination, due to the filtering activity of shellfis...

In September 2011, an acute gastroenteritis outbreak affected 33 children in Northern Italy. Patients had drunk river water during an excursion. Identical GI.4 norovirus genomes were detected from one patient's stools and from the river water. Improper discharge of human sewage into the river may have caused this waterborne outbreak.
