Hi I hope you are well
If you didn't get sick you should be fine. What kind of disinfectant did you put on the cutting board? Did you wash the board off after with water? It is not good to injest disinfectants. Most disinfectants will kill bacteria and viruses. But, maybe not parasites. However, you wouldn't generally get a parasite from blood in meat. Its usually in the tissue. Hope this helps.
