The purpose is to avoid consumers infection.
Bacterial contamination will cause no effects if the sample is tested directly after collection. However, if the sample is allowed to sit, bacteria will multiply and raise the urine pH. Urine pH above 8 is abnormal.
Ecoli doesn't develop on food. It reaches food through contamination.
it minimises the amount of bacteria in the immediate environment therefor slowing the process of contamination
touching raw chicken then cooked chicken with the same gloves
Cooking to safe temperatures will inactivate any bacterial contamination that was present.

That would depend completely on how long they have been unrefrigerated and if there has been any bacterial growth or contamination. If you don't know, it would be safest to discard the food.

Does not originate from fecal contamination.
