What are possible dangers that threaten the egg in outside environment?

Physical Dangers:

* Impact: Dropping or bumping the egg can crack or break the shell, damaging the yolk and white.

* Temperature: Extreme temperatures, both hot and cold, can damage the egg's contents.

* Heat: High temperatures can cook the egg or cause bacterial growth.

* Cold: Freezing temperatures can cause the egg to expand and crack.

* Sunlight: Prolonged exposure to direct sunlight can cause the egg to heat up, potentially cooking the egg or leading to bacterial growth.

* Moisture: Excessive moisture can lead to mold growth on the egg shell.

Biological Dangers:

* Bacteria: Eggshells are porous and can easily become contaminated with bacteria like Salmonella. This can cause food poisoning if the egg is eaten.

* Parasites: While less common, parasites like roundworms can infect eggs.

* Mold: As mentioned above, excessive moisture can lead to mold growth, making the egg unsafe to eat.

Other Dangers:

* Predators: Birds, rodents, and other animals may prey on eggs.

* Weather: Extreme weather conditions, such as heavy rain, snow, or hail, can damage or destroy eggs.

Note: The risks vary depending on the type of egg, the climate, and the duration of exposure. For example, a hard-boiled egg is more resistant to temperature changes than a raw egg.
