Be warned this is a site for apostate leaning JWs. True wutnesses do not have any open forums.
That said, the mosaic law says animals are to be bled. Not wringed out. Kosher meat is bled as is almost all American meat. Some jews will hang slices on a rack to let more juice drain. Note that cooked meat still has cooked blood in it.
You can ask your bible e teacher and the elders but be prepared for conflicting opinions. Note that they are opinions, not supported by WT law. It gets worse when assessing fractions of blood in medical procedures.
