"A little bit of dirt cleans out the stomach" is a Swedish saying used when people pick up some food that's fallen on the floor, and use it anyway.

At home there is no excuse for not being hygienic, and when eating out, one should definitely avoid cheap restaurants where there is reason to question hygiene.

In the UK, most of the health scares are about Chinese takeaway restaurants, or cheap Indian/Bangladeshi restaurants. I don't like either type of food.

One of my favourite grievances/annoyances are commericals about anti-bacterial wipes and sprays. That is such tosh and rubbish. It is certainly not needed! The use of such products are responsible for the rise of superbugs at hospitals.
Basic washing up liquid and maybe chlorine is all that's needed for cleaining in my opinion.
