Blood on croissant



today i bought two croissants for my wife an me.
As i ate mine, i found blood at the bite edge. It was still wet, mixed with salvia. I wiped it away.
So i believe, it was my own blood.
My question: If it wasn´t my blood, could blood stay wet after 3 hours after buying?
It was small like a pinhead. Or has it been dryed since it was such a small amount. Even on the surface of a croissant (fat)?
What is the chance to get HIV if the blood was contaminated? It came into contact with my teeth an the muscius membrane.
Best regards



Thank you for your inquiry. From what we gather from the question, you were asking about acquiring HIV from ingesting blood. From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario).

HIV transmission occurs when bodily fluid containing HIV has direct access to the bloodstream of an individual who is of HIV negative status through a high risk activity.

In the scenario mentioned there is no high risk activity that would present an opportunity for HIV transmission to occur. When blood is exposed to the environment the HIV would be rendered inactive due to oxygen (1). HIV can only be transmitted when there is direct access to the bloodstream. Therefore, biting a croissant where there may have been blood containing HIV from 3 hours beforehand would not be active and transmission would not occur.
Blood would not still be wet after 3 hours it would be dried at the point of contact.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
