E-coli, salmonella and campylobacteriosis are bacterial infections which in some cases can cause illness to the fetus. An infected fetus may suffer health problems after birth including diarrhea and fever, and in rare cases even meningitis.
There are two ways that salmonella can infect eggs. The bacteria can be passed on from an infected hen to the inside of the egg as it's developing, or it can get onto the outside of the shell after the egg is laid by coming into contact with the hen's feces.
