What is the ruling on eating pork unknowingly?

Eating pork is forbidden for Muslims. However, if one consumes it unknowingly, there is no sin upon them, as Allah Almighty says: "And there is no blame upon you for that in which you have erred, but [there is blame for] what your hearts intended," and the Prophet, peace and blessings be upon him, said: "Indeed, Allah has forgiven my nation for [their] mistakes, forgetfulness, and what they are coerced into." But if one knows that they have eaten from it at a time when vomiting is possible, they are obliged to do so if they can.
