2.- CHECK THE LABEL
Obviously in a restaurant, although you can ask for it, they do not expose the labels of their products to the public, but in fishmongers they are obliged to do so. If they don't, be wary. As consumers, it is our responsibility to learn to read product labels. The bluefin tuna label is your ID. It explains everything there. A correct label must include the following information:
- The brand of the product (the one that sells it, in our case JC Mackintosh), the contact details of the supplier (the one that fishes it, in our case Atún Rojo del Estrecho SL) and the contact details of the handler (the one that fishes it, in our case cuts and packs, in our case Isla de Tarifa SL).
- Trade name of the product, "Red Tuna", and scientific name, "Thunnus Thynnus"). If these two denominations do not appear on the label as is, be wary. The tuna, or Thunnus, is a genus of fish that includes about ten species. Only one of them is Bluefin Tuna or Thunnus Thynnus, but with the naked eye of inexperienced eyes and applying certain tricks (such as dyeing the meat with beetroot juice), the meat of all of them can pass for bluefin tuna. Some of these fish, which being tuna are not bluefin tuna, are albacore, light tuna, bigeye tuna, bluefin tuna, bighorn, longtail or blackfin, among others.
- The batch number, which is like your ID number, unique and non-transferable. The weight of the batch, the way in which it is presented, the capture area and the gear used to capture it. These last two are important if you want to know the origin of the tuna and the level of sustainability of its capture method.
- Capture date, packaging date and expiration date. JC Mackintosh only sells fresh bluefin tuna and its expiration date is calculated accordingly. In cases where the buyer is going to freeze the product and depending on the type of freezer it is, the expiration date would be different from the one that appears on the label. In any case, if you see from the label that a long time has passed since the fish was caught and the date of purchase, ask the seller to explain why.
- Sanitary registration number of the supplier and handler. On the website of the Spanish Agency for Food Safety and Nutrition (AESAN), belonging to the Ministry of Health and Consumption, there is a search engine where you can enter these numbers and you will get the name of the company to which this number has been assigned . Obviously they must match the name that appears on the label. If not, be suspicious.
