Crew departed with hazardous material on board; but our paperwork showed no Hazmat. We received our DG Manifest very early; before any freight was loaded top-side; which we found a little odd; but since it did say there was no Hazmat aboard; I did not think to question it. Enroute to ZZZ1; Operations Control sent ACARS message: '[…] update: agent advising that in 9L there is Hazmat unknown to the crew (toxic; radioactive; & dry ice) 3848 lb Hazmat; but not showing up on the weight and balance...being advised that there is something wrong in the auto DG system.' I do not know how or why this happened.
A300 Captain reported Hazmat was loaded prior to departure without crew notification.
