“…HEV RNA has also been detected in (2/230, 0.9%) herbs and spices (Loisy-Hamon and Leturnier, 2015). Despite some evidence of contamination of foods of non-animal origin by HEV, vegetarianism has been identified as a protective factor in several studies (Cossaboom et al, 2016;Sivasangeetha et al, 2016;Tedder et al, 2016).…”

Hepatitis E virus (HEV) is an important infection in humans in EU/EEA countries, and over the last 10 years more than 21,000 acute clinical cases with 28 fatalities have been notified with an overall 10-fold increase in reported HEV cases; the majority (80%) of cases were reported from France, Germany and the UK. However, as infection in humans is not notifiable in all Member States, and surveillance differs between countries, the number of reported cases is not comparable and the true number of cases would probably be higher. Food-borne transmission of HEV appears to be a major route in Europe; pigs and wild boars are the main source of HEV. Outbreaks and sporadic cases have been identified in immune-competent persons as well as in recognised risk groups such as those with preexisting liver damage, immunosuppressive illness or receiving immunosuppressive treatments. The opinion reviews current methods for the detection, identification, characterisation and tracing of HEV in food-producing animals and foods, reviews literature on HEV reservoirs and food-borne pathways, examines information on the epidemiology of HEV and its occurrence and persistence in foods, and investigates possible control measures along the food chain. Presently, the only efficient control option for HEV infection from consumption of meat, liver and products derived from animal reservoirs is sufficient heat treatment. The development of validated quantitative and qualitative detection methods, including infectivity assays and consensus molecular typing protocols, is required for the development of quantitative microbial risk assessments and efficient control measures. More research on the epidemiology and control of HEV in pig herds is required in order to minimise the proportion of pigs that remain viraemic or carry high levels of virus in intestinal contents at the time of slaughter. Consumption of raw pig, wild boar and deer meat products should be avoided.

Hepatitis E virus (HEV) is the most common cause of AVH in developing countries. HEV causes a self-limiting infection that is transmitted mainly through the consumption of contaminated food and water. Our study aimed to find out the seroprevalence of HEV infection. Detected both IgG & IgM antibodies from 100 asymptomatic antenatal women. ELISA (DIA PRO, Italy) was used to detect antibodies. Seropositivity was found in 9% of pregnant women, all might have been exposed to HEV infection previously. It could be unnoticed due to its self-limiting nature. IgG was 5% and IgM was 6%. Both IgM & IgG were detected in two pregnant women. Untreated water was used by the majority of women irrespective of their educational status. Though it is a self-limiting disease, it is necessary to screen for its antibody. Awareness about the modes of transmission & complications needs to be addressed in the community. It is necessary to do further studies for screening for HEV infection as there is a very limited number of studies published from South India.
