Poland: Eucharistic Miracle?

A priest in Assumption Church in Topola found on November 27 a piece of a consecrated host lying on the floor, a sacrilege common in places where communion is not received but taken with the hand.
He put the particle in water in order to dissolve it. In the process, the particle turned dark red. Two similar events occurred previously in Poland in Legnica (2013) and Sokółka (2008), where the red tissue resembled seem to be a human heart at the moment of death.
In other cases, e.g. in Salt Lake City (2015), red discoloration on a host was found Neurospora crassa, a type of red bread mold. Another agent responsible for the "bloody bread" effect is Serratia marcescens, a species of rod-shaped bacteria.
