"Is it worth it to expose people in the chicken industry to the salmonella microbe?"

sorry, but there are very simple sanitary guidelines for such situations that include the same ones you see in the washrooms of every restaurant. WASH YOUR HANDS AND DON'T FORGET THE SOAP!

By your thinking no one should work store check outs because standing by doors that are constantly opening in all weather conditions, handling filthy money and being exposed to sick customers is a sure fire way to get sick yourself. I know this from personal experience.

Life is not safe. That's why ignorance can get you killed. Risks can be managed rationally... we do it all the time.

We overreact to unfamiliar situations. There are plenty of improvements I want to see in food production... but knee jerk reactions are not helpful.
