One problem with EU regulation (or at least most regulations; a few have union-wide regulators) is that you're really quite dependent on whether your national responsible body is any good.

For something like this (assuming it's sold union-wide and not just in your country), it might actually be useful to notify the responsible bodies on _other countries_ (once it's actually investigated and recalled the recall should be union-wide).
