You are confusing a "Suggestion" with a "Requirement."Check with the health department, you are wrong.
"The Department of Health Services, Public Health Programs and Services, offers tuberculosis testing and treatment to all persons residing in Los Angeles County at a low cost or for free. Public health officials ask that food establishment owners or operators have their employees tested for TB since the disease is curable with proper treatment."
If it was required, it would not say "Public Health officials ask." It would say "It is required." Big difference.
Several years ago, my girlfriend's 11 year old son wanted to move here. They are from China.
When he started 7th grade, school administrators told her a TB test was required. He didn't want it. I checked & found that it was not a requirement. When the school people again insisted it was, I west to Olive View Medical Center & spoke to an RN who told me it was not a requirement & she printed the section of the law & gave it to me. When my girlfriend showed it to the school principal, he again said it was required. But after she asked if they were willing to go to court over it, he quickly changed his mind & her son was admitted.
If you let people walk all over you, you can't complain about shoe prints on your clothes.
