I lived in Japan for 7 years and just got back a few months ago. Somethings changed while I was gone related to food safely that stuck out at least for me.
#1. When I go grocery shopping. About 1 of 5 things I pick up is STICKY!! A jar of pickles, a carton of milk, a box of cookies. Whatever. I don't remember this experience of sticky items before I left
#2. At many or most food service places the employees are wearing disposable rubber gloves.
I don't know if some law was passed and if so if there was any proof of efficacy but it sure seems, watching the food service workers, that putting on rubber gloves is having the opposite of the desired effect. The problem is, with the gloves on they can't tell when their hands are dirty so they pick up some wet food, for example sun dried tomatoes coivered in oil, then they open the grill cover with their gloves not being able to feel how dirty their hands are. They spread this filth back on the food, back on handles, utencils, etc. If they were not wearing the gloves they'd notice their hands are dirty and would clean then before touching other things in the kitchen.
It also makes me wonder if the #1 issue above is for similar reasons. If stockers at the grocery store are also wearing gloves they'll have no idea if they are stocking the shelves with sticky hands and therefore making everything the put up sticky and a breeding ground for bacteria.
I don't really know how to research this issue but I really hope someone qualified can look into it.
