Hello Moderators,
I was with my friends out for dinner and the waiter was opening the foil onto of the cork using a knife. He gets a cut and bleeds. The blood might have come into contact with the wine and we immediately drank the wine.  
 
People say no one has ever gotten HIV from drinking or eating contaminated food but is it still true if the blood was so fresh?

Hi there,
Thanks for coming to the AIDS Vancouver online helpline for all your questions.  I hope that the following information helps:
In this specific example, while there was blood present, there was not an activity (unprotected anal or vaginal sex or sharing of needles) and direct access to the blood stream. As a result, there is no risk for passing HIV from the waiter to you. 
One of the main reasons that someone cannot acquire HIV from eating / drinking food with HIV+ blood in it is that HIV dies quickly when exposed to air, as HIV does not survive outside the body for more than a few minutes. In this example, while the blood was fresh, it was exposed to air and as a consequence created a no risk activity. Assuming the waiter was HIV+ & that his blood actually entered the wine bottle, any HIV in the blood would have died within seconds to minutes. Moreover, when eating or drinking, the HIV+ blood first comes into contact with your mouth & digestive tract & there is actually an enzyme in saliva which acts to inhibit HIV from entering the blood stream. So, this furthers decreases the already low risk of infection from the activity you described.
While we can say that this posed no or negligible risk of HIV transmission, in this example, there is, however, a risk of passing Hepatitis (A or C). If you are concerned about this incident, you might want to consider getting tested as a blood test is the only way to know.
Here is a link that can give you more information on this: http://www.avert.org/hepatitis.htm
 
Hope this information helps.  Let us know if you have any other questions. 
In Health,
Jaz
