Human Factors
I took over this flight at shift change and outgoing Dispatcher advised they had just received information about undeclared HAZMAT (hazardous material) being on the aircraft.  Service recovery advised that there were 98 packages of lithium batteries in position 2R; which was located too close to ADG (accessible dangerous goods) loaded in position 1L.  At this point; flight was about 3 hours out of ZZZ; notified crew of issue via ACARS; and after service recovery consulted with Duty Officer; determined no immediate safety issue existed; so flight continued to ZZZ1. I do not know what caused the issue; aircraft was already in the air when I found out about it and the error was with the loading of the dangerous goods and lithium batteries; anyway.  You would need to contact hub to find out the cause.
Air Carrier Dispatcher reported aircraft en route with Hazmat cargo was incorrectly loaded at departure. Flight continued to destination since no immediate safety issue existed.
