I agree with the above comment, i’m more afraid of the bagged salad kits vs some cold deli ham or turkey🥲 We see more outbreaks with those lately vs deli meat
The risk is minimal if any of the meat is heated all the way through. I believe a Reuben is a hot sandwich right? If so you should be fine!
I craved Reuben’s my first trimester and ate them often. That sandwich is hot so the meat is heated up so it should be safe!
Personally, I eat deli meat during pregnancy, especially if they’re heated up! The reason they were a no-no before is because they were a common source of listeria outbreaks, but these days, bagged salads are a higher risk than deli meat! The risk is even lower if the meat is heated, so I’d say go for it personally!
