First, restating the scenario and the answer choices helps frame the evaluation. The question asks whether an incident where two guests became ill after eating at a restaurant qualifies as a foodborne-illness outbreak, given that they ate different foods and experienced different symptoms. The options are:
1) Yes, because they ate different foods
2) Yes, because they ate different foods and had different symptoms
3) No, because they ate different foods and had different symptoms
4) No, because they ate different foods.

Option 1: Yes, because they ate different foods. This reasoning is flawed because a foodborne-illness outbreak is typically defined by a common source or exposure linking cases, not merely the fact that people ate different foods. Different foods would often suggest separate exposures rather than a single outbreak source.

Option 2: Yes, because they ate different foods and had different symptoms. While differing symptoms can occur in outbreaks due to individual susceptibility or varying doses, the key element of an outbreak is a plausible common source or point of exposure. Different foods reduce the likelihood of a single shared source, making this justification insufficient to declare an outbreak.

Option 3: No, because they ate different foods and had different symptoms. This option correctly emphasizes that a true foodborne-illness outbreak typically involves shared exposure to the same contaminant or source. If guests consumed different items and present with differing symptoms, it undermines the argument for a single outbreak linked to one source, suggesting separate incidents rather than an outbreak.

Option 4: No, because they ate different foods. While the fact they ate different foods weakens the case for a single-source outbreak, this statement omits the aspect of symptoms. Even if foods differ, one could still consider an outbreak in some atypical scenarios, but the absence of a common exposure or uniform symptom pattern makes this reasoning incomplete and not robust for labeling an outbreak.

Summarizing the assessment, the combination of different foods and different symptoms makes a single-source foodborne-illness outbreak unlikely, supporting the notion that it would not be considered an outbreak under standard definitions. The strongest justification centers on the absence of a common exposure and shared clinical profile among cases, which option 3 articulates. The other options fail because they hinge on shared foods, shared symptoms, or rely on an incomplete rationale that doesn’t align with outbreak criteria.
