Answer:
The possibility that the sandwich was responsible for the victim’s food poisoning can be explained by the following scenarios:
- Cross-contamination could have occurred if, without properly washing and cleaning between uses, the same cutting board and slicer were used to slice both raw meat and vegetables. Listeria and other diseases could spread from the raw meats to the rest of the sandwich if this happens.
- If the sandwich ingredients, especially the cut meats, weren’t refrigerated at the correct temperature, bacteria could have grown on them. This is due to inadequate refrigeration. Listeria monocytogenes is a form of bacteria that thrives in cold environments.
- The sandwich maker could have introduced harmful germs into the sandwich if they didn’t wash their hands or wear gloves before handling the ingredients. This is due to a lack of personal hygiene.
