Post-ASCT Diet: Eating Safely During Recovery

Last updated on: 3/25/2025

After an autologous stem cell transplant (ASCT), your immune system remains weak for months, increasing your risk of infections. Following a low-microbial diet can help prevent foodborne illnesses.

“I went through tandem ASCTs in 2019-2020. Before the transplants, I learned about the low-microbial diet and gradually changed my shopping, cooking, and food handling habits. I still follow many of the guidelines today.” – S. Turker

Always consult your doctor or nutritionist about your specific dietary needs and how long to follow these precautions. Generally, these guidelines apply for at least three months post-transplant.

Essential Food Safety Tips

  • Eat freshly prepared meals or frozen foods made at home.
  • Avoid buffets, self-serve food stations, and bulk bins.
  • Choose fresh fruits and vegetables without bruises or cuts. Wash and peel them before eating.
  • Store food safely: Refrigerate leftovers within one hour and consume them within 24 hours. Store eggs and milk inside the fridge, not in the door.
  • Cook foods thoroughly: Meat, poultry, fish, seafood, and eggs should be fully cooked. Steam vegetables when possible.
  • Avoid raw or undercooked foods, including sushi, raw eggs (in dressings, desserts), and unpasteurized dairy.
  • Skip deli meats, unless they’re pre-packaged and heated before eating.
  • Stick to home-cooked meals: Avoid restaurant food, takeout, or meals prepared by others.
  • Practice hand and surface hygiene: Wash hands frequently, clean cutting boards and utensils with hot soapy water, and use antibacterial sprays for surfaces.
