What an amazing list of expensive foods.
Even if I had money beyond compare, I would not spend that kind of money on something that my body is just going to turn into s*it. I'd give the money to charity instead.
As for food on the floor, even non-expensive food ... if
(1) the food is not sticky or wet
or
(2) I'm not going to be giving that piece of food to anyone else ....
I will eat it.
Most bacteria and viruses do not survive on the surface on a household floor, and it's not like the germs for Bubonic Plague or the HIV AIDS virus are lying there in wait.
I have a degree in science, including biosciences.
You would probably be safe licking the floor itself.
In fact, the more you avoid exposing your body to normal bacteria, the worse your immune system works. We have gone far in trying to keep our life free of all germs .. enough that it is compromising the immune systems of our children.
Certainly, one needs to avoid e.coli and salmonella ... and get your flu shots once a year. Apart from that, unless there is a quarantine put on your house by the Board of Heatlh, it's not likely there are any bacterial dangers there.
I have only had food poisoning once (along with my sister) and I am now 65 We got it from a restaurant hamburger, and my sister and I were the only ones who ordered hamburgers. We didn't have to go to the hospital and were back on solid foods in a few days.
