What is the ruling of Islamic law regarding wheat that was threshed by a wheat thresher that had consumed human blood?

Blood is impure. If it comes into contact with wheat, it contaminates the portion it touches, while the untouched portion remains pure. If an impurity falls into a solid substance, such as ghee, the impurity and the surrounding portion should be discarded, and the rest may be consumed. This is based on the hadith of Maymuna (may Allah be pleased with her) concerning a mouse falling into ghee. Al-Hattab al-Maliki was of the view that if an impurity falls into a solid food and it is possible for the impurity to spread throughout it, then the entire food becomes impure. Otherwise, only the affected portion becomes impure. If the contaminated portion mixes with other parts and its exact location is unknown, a large quantity of food should not be abandoned due to a small impurity whose location is not precisely known, as food is not to be discarded based on doubt.
