Anti-rejection medications keep your transplanted organ safe by deliberately dialing down your immune system — which also means your body is less able to fight off foodborne illness than it used to be. Food safety habits that were once just "good practice" become genuinely more important after transplant, not because ordinary food has become more dangerous, but because your body's ability to handle a foodborne infection, if you get one, is reduced. (See Transplant Anti-Rejection Medications and Diet After Transplant.)
Foods to Avoid
- Unpasteurized dairy and juice — raw milk, many soft cheeses (brie, feta, blue cheese, queso fresco) made from unpasteurized milk, and unpasteurized juice or cider
- Raw or undercooked meat, poultry, and eggs — including rare or medium-rare meat, runny egg yolks, and homemade foods that use raw eggs (like some Caesar dressing or cookie dough)
- Raw or undercooked seafood — sushi, sashimi, raw oysters, ceviche
- Deli meats and hot dogs, unless heated until steaming hot — these can carry Listeria, which grows even under refrigeration
- Unwashed produce, and pre-cut fruit that's been sitting out — wash all produce thoroughly, even if you plan to peel it
- Raw sprouts (alfalfa, bean, and similar) — genuinely difficult to wash clean of bacteria given how they're grown
- Moldy or damaged soft cheeses, and old leftovers — when in doubt, throw it out, rather than trying to salvage a food that's questionable
General Food Safety Habits
- Wash your hands before handling food, and wash produce thoroughly even if you'll peel it
- Keep raw meat separate from other foods, including separate cutting boards when possible
- Cook meat, poultry, seafood, and eggs to a safe internal temperature rather than judging by color or time alone
- Refrigerate leftovers promptly, and don't keep them longer than about 3-4 days
- Check expiration dates, and when in doubt about freshness, don't eat it
- Be cautious with buffets, salad bars, and food that's been sitting at room temperature for an extended period
How Long Does This Apply?
Immunosuppression is strongest, and infection risk therefore highest, in the first few months after transplant — but since some level of anti-rejection medication continues indefinitely, these food-safety habits generally remain worth keeping up long-term, not just early on. Your transplant team will give you guidance specific to your situation and how it may evolve over time.
Common Questions
Do I need to follow this forever?
In some form, yes — since you'll likely stay on anti-rejection medication indefinitely, though your team may relax certain specifics over time as your regimen stabilizes; ask what applies to your current situation.
Can I ever eat sushi again?
Ask your transplant team directly — this is exactly the kind of specific question where their guidance, based on your own regimen and how far out from transplant you are, matters more than a general rule.
What if I accidentally eat something on this list?
Don't panic — watch for symptoms like fever, vomiting, or diarrhea, and contact your care team if they develop; a single exposure doesn't mean you'll necessarily get sick.
Does this replace normal heart-healthy eating advice?
No — food safety and heart-healthy eating are two different, complementary layers; see Heart-Healthy Eating for the general pattern and Diet After Transplant for how everything fits together after transplant.
