What happened
On July 25, 1535, as Fr. Domenico Occelli broke the consecrated host at Mass in the Collegiate Church of San Secondo, blood ran along the break and fell into the chalice. He called the congregation forward to see it.
Bishop Scipione Roero reported the event to Rome, and Pope Paul III granted a plenary indulgence by apostolic brief that November. Honestly: the blood was not kept — the host was consumed at that Mass — so there is no relic to study, only the chalice and the Church’s formal act.
Where it stands
A formal act of the Church: at Bishop Scipione Roero’s report, Pope Paul III granted a plenary indulgence by apostolic brief (6 November 1535) to those visiting the church on the anniversary.
Church recognition is a judgment about devotion — not a claim of scientific proof. We keep the two distinct.

The bigger picture
This case is one witness in a much longer story — the Catholic teaching that Christ is truly, substantially present in the Eucharist.
