Torah says: "Don't eat blood". Dental Torah describes that only arterial and venous blood blood vessels is disallowed. Capillary blood blood vessels is permitted if it is at standstill. Essentially it means that even if there are no other blood vessels but capillary blood vessels in a item of various meats the problem still exists: during food preparation warmed capillary blood blood vessels will flow and become disallowed together with the whole item of various meats. That is why all blood blood vessels should be eliminated before steaming or cooking. Salting-out is a excellent way for its eliminating.

The blood blood vessels that doesn't drip out while food preparation and continues to be in various meats is permitted.
