All of your bad bugs and danger come from contamination during processing. Buy as much of your food from local farmers and producers who follow good hygiene and you will be fine. Do I trust a bag of spinach which has been mingled with tons of other spinach leaves in large processing facilities where one single "oops" can contaminate millions of bags or the bag of spinach I get at the farmers market from the producer I talk to every week and whose farm I have visited? I'll take local.
You are more likely to get sick from eating at a mexican restaurant where one of the staff forgot to wash their hands than a sushi restaurant which follows good hygiene practices.
Regarding raw milk, the CDC finally released figures that allow one to calculate the risk of consuming raw milk compared to the risk of consuming other foods.
“Using government figures for foodborne illness for the entire population, Dr. Beals has shown that you are about thirty-five thousand times more likely to get sick from other foods than you are from raw milk, and with good management practices in small grass-based dairies offering fresh unprocessed whole milk for direct human consumption, we may be able to reduce the risk even further.”
Pasteurized milk is more dangerous than raw milk in the long run and probably even in the short run.
