This is a controversial question, and the answer is upto personal choice . The FDA recommend that meat should not be washed due to bacterial contamination. The risk is especially high in the case of chicken and ground mince. However, the idea of not washing meat is unpalatable in a Desi / South Asian household. I personally do not prefer washing ground mince; however, I only buy from butchers and supermarkets where I can see it is clean and hygienically packaged. Otherwise I will get boneless chicken, and make my own chicken mince using a food processor. In that case, I can wash the larger chicken pieces and don’t need to wash the ground mince afterwards. If you do choose to wash ground mince use a fine mesh strainer, along with gloves to handle the meat. Sanitize the sink and surface areas afterwards.
