OK, so we all know that some people have allergies and where a product has ingredients that may trigger those but it may not be obvious they are in there, then they should make it known on the packaging.
Some things, however, just seem to go too far. I just had a very nice piece of Sea Lord hot smoked salmon for lunch.
On the packaging (With 'Hot Smoked Salmon written all over it in big letters) it says...."Contains Fish".
No s**t, Sherlock.
