Answer:
The chefs who were preparing food for the company picnic did not know much about safe food handling and the risks of contamination. During preparation, raw chicken was left beside vegetables, including lettuce and tomatoes, that would be used for both the egg salad and the green salad. The chicken, after sliced, were never cooked properly, allowing the bacteria to live. The lettuce and tomatoes were not washed after having touched the raw chicken. Since salads are not cooked, the bacteria on the vegetables were not killed either.
Explanation:
Campylobacter can be found in poultry, like chicken. Contamination can happen with direct contact and not washing foods.
If some living things do not reproduce this could be considered a defect or a genetic mutation in those people. If we take humans for example, if most humans reproduce and some don't because they cannot (if a guy cannot produce sperm) this doesn't mean that he isn't alive, it just means he was born with a genetic mutation which doesn't allow him to produce sperm needed for reproducing.

What is the easiest way to recognize foods contaminated with spoilage bacteria?
The easiest way to recognize foods contaminated with spoilage bacteria is when you observe the color change and smell. When the color has got very unprepossessing, and the smell is a bit awful. A bit greenish, blackish on the bread, its straight away a contaminated food with spoilage bacteria leading you to illness.
Hope I helped (:
Have a great day!
