Introduction
Under normal circumstances, food does not cause HIV infection, but extremely rare cases involving blood contamination should be taken seriously. HIV transmission occurs only through specific routes; everyday eating or sharing meals do not meet the conditions for transmission, so there is no need for excessive fear. In daily life, avoid sharing personal items such as toothbrushes and razors that might come into contact with blood. When dining out, choose hygienic establishments and ensure food is thoroughly cooked.

Under normal circumstances, food does not cause HIV infection, but extremely rare cases involving blood contamination should be taken into consideration. HIV transmission occurs only through specific routes; everyday eating behaviors or sharing meals do not meet the conditions for transmission, so there is no need for excessive fear. The detailed analysis is as follows:

HIV primarily exists in bodily fluids such as blood and semen of infected individuals, and the virus has very poor survival ability outside the body, being highly sensitive to heat and gastric acid. High temperatures during food preparation rapidly inactivate the virus. Even if a small amount of virus enters the digestive tract, it will be destroyed by gastric acid and digestive enzymes, making it impossible to enter the bloodstream. To date, there have been no documented cases worldwide of HIV transmission through regular eating. Sharing meals or utensils with infected individuals is safe and poses no risk.

Theoretical risk exists only in extremely rare situations—such as when an infected person with oral bleeding chews food containing their blood, and another person with open wounds or ulcers in their mouth consumes that food. However, even this scenario is exceptionally uncommon. Such transmission would essentially result from direct blood contact, not from the food itself, and therefore cannot be considered evidence of food-borne transmission.

In daily life, avoid sharing personal items such as toothbrushes and razors that might come into contact with blood. When dining out, choose hygienic establishments and ensure food is thoroughly cooked. There is no need to deliberately avoid people living with HIV; understanding the scientific facts about transmission routes enables better self-protection.
