生（なま）: An uncooked state and checking a raw egg’s shell
Read 生 as なま for an uncooked state. Separate the particular fish’s stated possibility from the object checked before cracking a raw egg.
生 names an uncooked state
In these examples, 生 is read なま and means raw or uncooked. 「この魚は新鮮なので生でも食べられる。」 says this fish is fresh enough to be eaten raw. 生 names its uncooked state.
新鮮なので states a reason concerning this fish, while 食べられる expresses possibility. That particular state, reason, and possibility do not establish a rule for every fresh fish.
The raw egg and its checked shell
「生の卵を割る前に殻をよく確認した。」 reports carefully checking the shell before cracking a raw egg. 生の modifies the egg as uncooked.
The checked object is 殻, the shell, and 割る前に locates the check before cracking the egg. The check’s object and the egg’s uncooked state are separate pieces of information.
Cooking state and other properties
生 names the uncooked state here; 新鮮 names the freshness stated about a particular fish. Rawness, freshness, and whether something is frozen are different properties.
The egg sentence reports checking its shell. The action alone does not establish confirmed freshness or safety.
