Here's your procedure to get hatching eggs exported from the US to Israel.
The nefarious ways of getting birds to which you have referred is how these things spread.
People that should know better bring in things on the sly. The rules are there for a reason.
I knew a person that worked for the US govt. working in Costa Rica. He carried hatching eggs to CR without any of the documentation because he could.
Yes the reason is to eliminate the chance of pathogen transferring,
If so how the egg that are imported by the government itself are infected and causes death and disease?
I want eggs from Israel!!
