Final answer:
Sneezing, coughing, and not using a tissue can contaminate food. Using a tissue to cover the mouth and nose when sneezing or coughing helps to prevent the spread of pathogens and protects food from contamination.
Step-by-step explanation:
True. Sneezing, coughing, and not using a tissue can contaminate food. When a person sneezes or coughs, tiny droplets containing pathogens are expelled from their respiratory tract. These droplets can contaminate nearby surfaces, including food, if proper hygiene practices are not followed. Using a tissue to cover the mouth and nose when sneezing or coughing helps to prevent the spread of pathogens and protects food from contamination.
