An egg with a blood spot

Hi,

We have noted that one may not eat eggs that contain blood spots.

There is some debate as to whether one need throw out the whole egg, or not; some of this depends on where the blood is found, within the egg.

Because it is exceedingly unlikely that eggs marketed in North America will have been fertilized, many authorities are lenient and permit throwing out the actual spot and eating the rest of the egg. We may assume that the spot did not come from an embryonic chick.

Have a great day,
