A food safety hazard refers to any element present in food that poses a risk to consumers. Such hazards can be biological, chemical, or physical. Their presence may lead to both illness and injury. Specifically, if a cleaning solution is used on a frozen yogurt machine, it must be handled carefully, as it may contain harmful chemicals. These substances can enter the body and lead to serious health issues, classifying this scenario as a chemical food hazard. To mitigate these risks, proper cleaning of the solution after use is essential.
