Can you tell if a food or surface is contaminated with bacteria simply by looking at it?

No,you can not tell by looking . If in doubt - clean it.

Visually inspecting would not be the most reliable way of determining contamination. Only if the surface is actually dirty would it be likely to be contaminated. However if it looks clean it can still be contaminated.

No, bacteria are microscopic. You cannot see them without a microscope, which is why it is so important to use good cleanliness and food safety practices.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
