The “common name + scientific name” recommendation — this is good practice advice rather than a stated legal requirement in the text of Regulation (EU) No 1169/2011 itself; I've presented it as practice/interpretation rather than a hard rule, but worth double-checking that this framing is accurate and not overstated.
CMO labelling scope boundary (“essentially unprocessed or minimally processed form”) — this distinction between when the CMO-specific labelling applies versus when only the general food information rules apply is my interpretation of how Annex I to the CMO Regulation and the general food law interact; a kind of boundary question, a real citation is required, maybe a case-based confirmation…
I also added a statement on frequent violation of the aquaculture labelling rule - maybe too strong.
Allergen status of algae — algae are not among the 14 recognised EU allergens (?) Verify again! cross-contact risk with fish/crustaceans (or nuts) in shared facilities - a general statement.
