Hello, and I hope I can help you today. I know that it is advised to avoid raw or undercooked meat during pregnancy, but if the steak you ate was from a reputable restaurant or butcher, the meat is unlikely to be contaminated with toxoplasmosis. Toxoplasmosis is present mostly in vermin and birds, which is why cats frequent y are carriers. It is also endemic in parts of Europe, so imported meats sausages and cheese also should be avoided. Furthermore, catching toxoplasmosis is really only harmful during early pregnancy. So you really do not have to worry about accidentally eating a small amount of undercooked meat. I hope I was able to adequately answer your question today and that this information was reassuring. Best wishes for the rest of the pregnancy, Dr. Brown
