I actually find that the "germ phobics" are often the sickliest people. I am a believer that you keep your immune system healthy by exposing yourself to germs. Just like a fit runner will fall out of shape quickly if he does not run a certain number of miles a week, so will your immune system. I'm not saying be stupid about it. Obviously you want to maintain a standard of hygiene.
Celebrities like Howard Hughes and Michael Jackson were germ-phobic and they had miserable lives. Remember Michael Jackson walking around with his surgical mask so that he could avoid other people's germs?
Let your system rassle with a few microbes and eat live garlic to give your fighters an edge, I sez.
Surprise food inspections, lol. There have been stores and restaurants that have been in business for decades which have never had an inspection. Most of the country has never seen an inspector. There is not enough funding to hire enough inspectors to cover then entire food industry.
