First of all, I'm going to talk instead about species that we refuse to commercialize. Metro annually monitors certain sensitive stocks and vulnerable species. We have a list of temporarily withdrawn species, and we systematically refuse to accept any of those products that suppliers offer us. A few examples appear on the list that we've published on our website. They include certain tuna, shark and ray species.
As I said, we monitor the situation annually. I've been working in this specific field for four years, and I've seen significant improvement in stocks only once. It was the deepwater redfish, which we reauthorized for listing and sale.
As for suppliers, I don't have any specific examples for you because our job is really to evaluate products and species. We may reject certain products from a supplier because the traceability is incomplete or we doubt its veracity. We may also accept other products from that supplier for which it has demonstrated a complete procurement chain.
