in thread iterating hash keys?

... am I missing something?

You're missing what BrowserUk said here, an approach that processes an entire line at a time.

The next part to think about is what happens if you encounter a 'word' in a line that doesn't exist in your translation hash, e.g., the line
    "peaches,peaches,foobar,kiwis\n"
(hints: exists, next, maybe  // (defined-or) or  ?: (ternary/conditional operator) – see perlop for the latter two).
