The other day my uncle started eating a grilled cheese sandwich he put his half eaten piece on the plate and than laid a newly made sandwich on top of his half eaten piece I then proceeded to eat the new sandwich. If my uncle had a cut in his mouth got blood on his sandwich and it transferred to my sandwich could I be at risk? I also had the start of a canker sore on the inside of my bottom lip I've read that blood on food isn't a source of transmission but couldn't the canker sore be one?
Response from Ms. Southall
Hi If the blood on the sandwich was significant, just placed there and you immediately picked it up and took a bite with an open canker sore than yes this could be a risk, but highly unlikely.
Be well and stay safe, Shannon
