There are bacteria in salmon when eaten raw, but there is no problem. There are not many bacteria when eaten raw. You cannot simply say that eating raw salmon is "somewhat" or "not" dangerous. Safety first depends on the fish itself. If the fish itself does not have parasites and disease-causing bacteria, then there will naturally be no problems. If there are a certain amount of parasites and disease-causing bacteria, then reasonable processing can fully kill them. However, it is difficult for us to judge whether fish contain these "risk factors", and it is not necessarily clear whether they have undergone standardized and qualified pretreatment. Eating it raw does not necessarily mean there is a problem, but the risk is higher.
