If a food handler had the flu how can this virus be transferred to the customers who eat the food?

If a food handler has the flu, the virus can be transferred to customers through contaminated hands or surfaces. When the food handler touches food, utensils, or food preparation areas after coughing, sneezing, or touching their face, they can introduce the virus to the food. Additionally, if the food is served without proper cooking or handling, the virus may survive and infect customers when they consume the contaminated food. Proper hygiene practices, such as handwashing and staying home when sick, are essential to prevent such transmission.
