Abstract Background Hepatitis E virus (HEV) genotype 3 and 4 is a zoonosis that causes hepatitis in humans. Humans can become infected by consumption of pork or contact with pigs. Pigs are the main reservoir of the virus worldwide and the virus is present on most pig farms. Main body Though HEV is present on most farms, the proportion of infected pigs at slaughter and thus the level of exposure to consumers differs between farms and countries. Understanding the cause of that difference is necessary to install effective measures to lower HEV in pigs at slaughter. Here, HEV studies are reviewed that include infection dynamics of HEV in pigs and on farms, risk factors for HEV farm prevalence, and that describe mechanisms and sources that could generate persistence on farms. Most pigs become infected after maternal immunity has waned, at the end of the nursing or beginning of the fattening phase. Risk factors increasing the likelihood of a high farm prevalence or proportion of actively infected slaughter pigs comprise of factors such as farm demographics, internal and external biosecurity and immunomodulating coinfections. On-farm persistence of HEV is plausible, because of a high transmission rate and a constant influx of susceptible pigs. Environmental sources of HEV that enhance persistence are contaminated manure storages, water and fomites. Conclusion As HEV is persistently present on most pig farms, current risk mitigation should focus on lowering transmission within farms, especially between farm compartments. Yet, one should be aware of the paradox of increasing the proportion of actively infected pigs at slaughter by reducing transmission insufficiently. Vaccination of pigs may aid HEV control in the future.

Hepatitis E virus (HEV) and Salmonella bacteria are zoonotic pathogens that can be acquired by foodborne transmission because food animals, for example pigs, are recognized as a reservoir. The objectives of this study were to determine the seroprevalence of anti-HEV immunoglobulin G (IgG) and anti-Salmonella antibodies from healthy pigs at slaughter in Switzerland, a country with a good health status of pig herds (e.g., eradication of enzootic pneumonia) compared with those of many countries in the European Union, and a rate of importation of live pigs that is very low (<1%). Based on pooled (diaphragm muscles from 3 to 5 animals per producer) meat juice samples, 120 (60%) of 200 and 8 (4%) of 200 samples were positive for anti-HEV IgG and anti-Salmonella antibodies, respectively. HEV seems to be highly prevalent among fattening pigs in Switzerland, whereas the low seroprevalence of anti-Salmonella IgG has not changed in recent years.

Introduction: Hepatitis E virus (HEV) is one of the most prevalent cause of acute hepatitis in humans worldwide. The risk of HEV transmission is not limited only to spread from human to human but the infection can also spread from animals to humans, especially from the domestic pigs. Despite mounting evidence regarding the zoonotic potential of porcine HEV infection, there are limited data on its prevalence in pigs in the sub-Sahara Africa region. Therefore, the present study aimed to determine the seroprevalence of HEV antibodies among pigs in two Cameroonian regions. Methodology: A total of 162 sera were collected from slaughtered-age pigs from January to March 2012. To determine whether pigs might represent a HEV reservoir in the Northern and Western region in Cameroon, anti-HEV IgG and IgM were tested by ELISA using commercials available kits. Results: Overall, 70 of the 162 samples (43.2%, 95% CI: 35.5% - 51.2%) were positive for at least one of the serological markers of HEV infection (IgM and / or IgG).We observed a significant seroprevalence of HEV antibodies between the northern and western regions (60% (42/70) and 40% (28/70), p = 0.01796) respectively. Conclusion: Overall, this study reports a high seroprevalence of Hepatitis E virus antibodies in slaughter pigs in Cameroon. Our findings suggest that pigs might be a cause of zoonotic HEV transmission in Cameroon. Therefore, further studies are warranted to establish the dynamics of zoonotic HEV and characterize the different genotypes circulating in humans and pigs.

Toxoplasma gondii , hepatitis E virus (HEV) and Salmonella are zoonotic foodborne pathogens that may be transmitted to humans through the consumption of raw or undercooked pork.  The aim of this study was to determine the seroprevalence of anti- Toxoplasma gondii , anti-HEV and anti- Salmonella antibodies from healthy pigs at slaughter in Switzerland. In the period of August to September 2020 diaphragm muscle of Swiss fattening pigs was collected in three Swiss abattoirs from a total of 188 farms. Two randomly chosen pig carcasses per farm were selected. On the basis of the slaughter data, the production system and the canton of origin were noted, comparing indoor (n=120) and free-range farming (n=68), and regional allocation. The meat juice of these samples was analyzed for pathogen-specific antibodies using commercial enzyme-linked immunosorbent assay (ELISA) kits. The seroprevalences were 1.3% for T. gondii , 71.8% for the HEV and 5.3% for Salmonella , respectively. Comparing the origins, the results of many cantons weren't meaningful due to the low number of samples. No regional accumulations were found for T. gondii and the HEV. The results showed that 2.1% of the farms had least one T. gondii seropositive animal, 80.3% had at least one HEV seropositive animal, and 8.5% had at least one Salmonella seropositive animal, respectively. The seropositivity of T. gondi i was higher in free-range pigs than in indoor pigs, whereas anti- Salmonella antibodies were more common in pigs from indoor farming than in outdoor pigs. The seroprevalence of anti HEV-Abs was similar in free-range and indoor farming pigs. Compared to studies from 2012 the seroprevalence of T. gondii has decreased whereas the seroprevalence of the HEV has increased and is highly prevalent among fattening pigs in Switzerland. The low seroprevalence of Salmonella has remained stable in recent years.
