That would be the local CDC, you can tell the building and it's employees by the symbol"it's the same as a military doctor, cross and a snake climbing to the top" they are also in charge of quality and safeness of foods. If you're in a big city, it will be easy to find for the letters CDC are clearly seen on the front along with it's logo. Smaller cities usually only have the logo. You can also go to the local quaranten office, same logo. That being said, if you go to them, you better be sure, they are serious about this stuff, and if you are wrong or the company proves you wrong, you will be sued for a large sum of money. If you go to the PSB, you could run into a problem with an officer knowing the person you are speaking of and will cause a large amount of problems.

you can see a small display board with all the numbers of food control board. ring them. lets take down the bad people. lol
