I worked at a Coke bottling plant one summer, I got this really nasty bug from working there, It was in the 80's to 90's on the plant floor, fans going everywhere, and water spraying everywhere, so I would be warm and damp, then the only place to take breaks was the break room, which was kept at around 60 degrees... so I caught a bug from going from warm and wet to cold and wet back and forth every night (plus my system adjusting to the night shift). Anyway, the bottles come off of a pallet and go down a conveyer before being filled or capped, one night they put me up there where I was having to handle the bottles and stand over them while they went down the conveyer... I was coughing, blowing my nose, snot dripping... it was gross... and I was up there with the open containers... I looked out for those lot codes for a while when purchasing soda... I didn't want my bug back!
