Can HIV survive in cow milk? I'm concerned that somehow, someone has contaminated the milk I bought, with HIV, and I'm worried of ingesting said milk, and/or getting it on my hands and then transferring it to other places such as inside anus/penis when washing/going to the toilet.
Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through the avenue of ingesting cow milk that you believe to contain HIV positive fluid.
From the information given, this scenario is determined to be No Risk (HIV transmission is not possible in given scenario). Cow's milk is not considered to be an avenue for HIV transmission. Fluids that are known to carry HIV include: blood (including menstrual blood), semen, pre cum, vaginal fluid, rectal secretions, and human breast milk. In the context of your question, if you are concerned that HIV positive fluids can survive in a carton of milk, and, when consumed, cause HIV transmission; this is not possible.
HIV is extremely volatile and does not survive long outside of the human host (1). For this reason, any HIV positive fluid that you may have ingested or transferred to your anus/penis while going to the toilet would not be considered a risk for HIV acquisition.
Recommendation: No need for HIV testing, please refer to health care provider for other health related questions.
All the best,
