True or False: Eggs can become contaminated through the shell.

Eggs can indeed become contaminated through their shell because the shells can carry harmful bacteria, such as Salmonella. These bacteria can originate from various sources, including the environment in which the eggs are produced, and can be transferred to the eggs during laying.

Proper handling is critical since the porous nature of eggshells allows bacteria to potentially penetrate the shell. This means that even intact eggs can pose a risk if the shell is contaminated. This emphasizes the importance of washing hands and surfaces after handling eggs and cooking eggs properly to eliminate any potential pathogens.

The other choices do not encompass the full range of contamination risks that eggs face through their shells. For instance, contamination can occur whether the egg is cracked or not, highlighting the significance of safe handling practices for all eggs.
