Which of the following is a safe practice for re-serving food?

Re-serving unopened, prepackaged food in good condition is a safe practice because it maintains the integrity of the food and minimizes the risk of contamination. Prepackaged food is sealed in a way that protects it from exposure to contaminants and pathogens, ensuring it can be handled by multiple customers without concern. As long as the packaging has not been tampered with and remains intact, the food is safe to offer to another customer.

In contrast, re-serving uncovered condiments poses a risk of contamination from airborne pathogens or customer handling. Re-serving uneaten bread is also problematic, as bread can be susceptible to contamination through contact with customer utensils or hands. Lastly, plate garnishes that have been served with a meal can also pose a risk due to potential exposure to pathogens after being on a plate. Therefore, option B stands out as the only choice that ensures food safety standards are maintained.
