Final answer:
Sore throat, mild cough, and watery eyes from option d are symptoms that might restrict a food service worker's duties due to their potential association with foodborne illnesses or food allergies. These symptoms are most concerning for food safety and could indicate a contagious condition.
Step-by-step explanation:
Based on the information provided and considering the guidelines for food service workers, symptoms that might restrict a food service worker's duties include those that could be associated with foodborne illnesses or food allergies. Among the options, letter d, which lists sore throat, mild cough, and watery eyes, align with symptoms that may indicate a contagious condition or an allergic reaction, potentially affecting food safety. These symptoms are likely to cause concern in a food service setting as they can be related to illnesses that are transmissible through food.
Option b, involving cuts, bruises, and minor burns, could also restrict duties, particularly if the injuries are not properly covered, as they pose a direct contamination risk. However, cuts and burns are not symptoms but rather injuries that require proper treatment and covering. Options a and c list conditions that are generally not associated with foodborne illness or transmissible diseases but could impact a worker's ability to perform tasks if severe enough.
