Is the word salgada the same in Brazilian and European Portuguese?

Yes

The word "salgada" is identical in meaning, grammar, and spelling in both Brazilian and Continental Portuguese. The primary difference lies in pronunciation.

In most regions of Brazil, the "d" in "salgada" is palatalized, meaning it is pronounced with a "dj" sound (like the "j" in the English word "juice"). In Continental Portuguese, the "d" is dental or alveolar, pronounced with a hard "d" sound (similar to the "d" in the English word "dog").
