Yep, he says the steak come from the usual Elgoibar suppliers, or at least that's how I interpret it. He says the traceability is perfect, but then goes on to explain that, apparently, you can't go back further back from the supplier, which I found rather odd. Maybe he just means that he, as the shop owner, has no way of knowing where the meat ultimately came from (other than "from our usual Elgoibar suppliers") and that the authorities would know, but then it's odd to claim he knows it wasn't Basque (maybe he's just trying to avoid the Basque meat industry from becoming tainted in the eyes of the public opinion?).
Anyway, according to him, he bought all his meat from the same Elgoibar suppliers. I don't know if these were mere intermediaries or the actual slaughterhouse, but at any rate his version is that the meat/animals that got to Elgoibar weren't Basque.
