The pork thing is also a bit of momentum. It was problematic to eat raw pork in the US before 1980 when Congress passed the Swine Health Protection Act. This prohibited feeding swine with trichinella-contaminated food, which was the parasite most likely to get you sick. [2] The risk these days is almost negligible and we're seeing restaurants starting to serve pork cooked pink in the middle. [3]
Eating raw chicken is generally considered to stupid in Japan, unlike fish, horse or beef. It's shame that some restaurant provides that. Almost all people don't eat random raw chicken at home, but some eat at restaurant. Maybe alcohol drinks makes wrong risk evaluation. https://www.fukushihoken.metro.tokyo.lg.jp/shokuhin/eng/faq/...
For what it's worth, I'm quite unlikely to eat any raw meat at home because I know it's higher risk and that I don't feel I have sufficient experience to prepare it myself - or to know where to source meat suitable for consumption raw. I trust a chef at a restaurant however because it's both their job, and if they do it wrong, they won't be in business much longer.
