: Cases of hepatitis E have been caused by infection with hepatitis E virus (HEV) due to consumption of raw or undercooked game meats and liver of wild boars or deer in various countries. We investigated HEV prevalence in wild boar and deer in Okazaki City and its outskirts, Aichi, Japan, using liver samples (439 boar; 185 deer) collected between April 2010 and November 2014. HEV RNA was detected in 49 (11.2%)of 439 and 0 of 185 samples of wild boar and deer, respectively. The positive rate (13.0%, 28/216) of HEV RNA from the wild boar with estimated body weight of less than 40 kg was significantly higher than that (2.7%, 3/111) in animals with estimated body weight of more than 40 kg. The 49 HEV strains were typed as genotype 4 (G4) by phylogenetic analysis. They clustered with Aichi/Shizuoka strains and 48 of the 49 strains subclustered together (Okazaki strains).

The mean concentration and daily intake of five preservatives were estimated based on the results of an analysis of 89,927 samples of food obtained in official inspections by Japanese local governments in fiscal year 1998. The mean concentration of benzoic acid was 9.5% of the allowable limit, and those of dehydroacetic acid, p-hydroxybenzoic acid, propionic acid, and sorbic acid were 1.5%, 5.7%, 1.7%, and 23.9%, respectively. Daily intake levels of these preservatives per person estimated from the concentration and daily consumption of foods were 6.23 mg, 0.0303 mg, 1.02 mg, 8.10 mg, and 25.0 mg, respectively, and assuming a body weight of 50 kg, the amounts of benzoic acid, p-hydroxybenzoic acid, and sorbic acid consumed were 2.5%, 0.2%, and 2.0% of their acceptable daily intakes, respectively. These values were similar to those obtained based on the results of the official inspections in fiscal years 1994 and 1996.
