(1) There may be cases where a spleen will have sixty within itself against its forbidden fats, and be permitted. However, since we are dealing with a serious prohibition, one may never assume so, and the spleen must always be measured for sixty.
(1) The gizzard of poultry contains blood, and is not considered as the other intestines that don’t contain blood.
(2) The reason is because we fear that there may be some fat attached to them.
(3) It is not comparable to section 69, where we said that all meat must be slated on both sides. This case is different, for there is not as much blood in the fat as in other parts of the meat.
(4) We are not worried that the inner side will absorb from the outer side, since there is not much blood in the first place.
(5) They should not be salted with meat. Being that here is no blood or tzir, so we are worried that it will absorb it from the meat. Even if the shell is hard it can still absorb just as earthenware can absorb. This is the halacha to be followed.
