In only 1 line! 
%new_hash = (split(/;/,$variable_with_keys_and_values));

[download]
For example: 
%new_hash = (split(/;/,'apple;good;banana;good;citrus;good;no doughnut
+;bad cop'));

print $new_hash{'no doughnut'};

[download]
Outputs the value associated with the key 'no doughnut'

    This would probably be more clear if you said print $new_hash{'doughnut'}; instead of print $new_hash{'no doughnut'}; There is no item with key 'no doughnut'.

      Thanks; Anonymous Monk had originally had everything say "doughnut". one of the QandAEditors changed it to "no doughnut" and apparently flubbed it. Now fixed.
