You are not alone with this excellent question!
Food safety must be a priority for us due to our immunosuppression. With a newly transplanted organ, it does feel overwhelming, at least it was for me. I was afraid and confused about what to eat and how to do it safely, too. I am fortunate to have family and friends who were very cooperative and learned along with me. Will you trust me when I say that over time, food choices and preparation become a a normal part of your new way of healthy life? Instead of thinking 'restrictive' , I like to think 'healthy'.

As a volunteer mentor, I like to connect members to others with similar interests. So - here is one (with editor note) that has been helpful and informative for many transplant members.

@sec1205, I think that I remember being told to avoid raw veggies in the beginning, but I can't remember how long that was. Washing the veggies and fruits is a must. Proper cooking methods and cooking to proper temperature are also important. Buffets and potlucks are not a good idea, either.
And YES masks are still in! Last week at Mayo, I was told that, "You are immunosuppressed. And that Covid is still around, along with other infections."
