Many people don’t think eggs carry listeria; however, any animal foods can be contaminated with the bacterium. This depends on whether the hen where the eggs came from was a carrier or was infected with listeria. Otherwise, then the bacterium is not present. Eggs can also be contaminated with listeria if they come into contact with the bacteria once the shell has been cracked open. Although an egg could have listeria, it is unlikely to be found inside the egg, as the bacteria live on the shell. To be on the safe side, always make sure that you cook your eggs properly.

Just because you ate an egg that had listeria bacteria, it does not necessarily mean you’ll be infected. As a matter of fact, there are people who hardly show signs of infection. Nonetheless, you could get listeriosis and symptoms will start to show as early as three days after infection. In other patients though, they may take longer to exhibit listeria infection symptoms, and can even happen after two months. On average, it takes about three weeks to show signs of listeria monocytogenes infection.

For such people, even with prompt administration of antibiotics, they may end up kicking the bucket as the bacteria overwhelm their bodies.
