Hello doctor,

Is there any chance of hepatitis B spread through eating food contaminated with infected blood?

Hello,

Welcome to icliniq.com.

Well, the whole blood and serum (white fluid within blood) contains large amount of virus, and virus can live on blood spots outside the human body for the duration of one week. So actually it depends upon how much blood, and how much time it has been on the stain that can determine the chances of acquiring infection if contaminated with food. So I guess my answer can be partially answering your query.

If you tell me the exact event I may be in a better position to tell you the figures. Otherwise, as a general rule, hepatitis B does not spread via food, having said that, it can still spread if blood contaminated food has been ingested. Since virus invades the human body when comes in close to mucosa (lining of our mouth) and then spread to blood within human. This happens in the same way as one infected person can transmit infection via kissing, hugging, sharing of a towel, spoon, plates, and so on.

If you are puzzled with all that information, I want you to simply get a blood test for hepatitis B infection. It is a simple blood test that can give us a clue.

I hope this helps.


The Probable causes:

Post-exposure risk stratification.

Investigations to be done:

Hepatitis B surface antigen. Hepatitis B core total.

Regarding follow up:

Follow up after testing.

Hello,

Welcome back to icliniq.com.

Again to be very realistic with you it is plus minus call. Dried blood does not contain as much amount of virus as that of a fresh blood sample. To summarize, yes, there are some chances of acquiring infection.
