When we mate with someone with a completely different gene pool, our chance of passing on recessive genes is only 50 percent. Many times, those genes remain dormant, but when people who share a large number of genes breed (inbreeding), the chance of passing on conditions known as autosomal recessive disorders—conditions that are inherited through recessive genes, including cystic fibrosis, sickle cell anemia, and albinism—increases significantly.

I think it's safe to mate with cousin, but it shouldn't be between parent&child or siblings.
