Explanation:

1. For question 1, a food - borne illness outbreak must be confirmed by laboratory analysis. The number of people, number of foods, and symptom differences are not the defining criteria for an outbreak.
2. For question 2, since the two guests ate different foods and had different symptoms, it is not an outbreak as an outbreak typically involves people getting sick from the same food with similar symptoms.
3. For question 3, a food - borne illness outbreak is when an operation serves contaminated food to two or more people.
4. For question 4, at least 2 people with the same symptoms from eating the same food are needed to consider it an outbreak when other criteria are met.
5. For question 5, pathogens pose an increasing challenge because they are being found on food items once considered safe.
6. For question 6, high - risk customers pose an increasing challenge because their numbers are on the rise.
