Steve,
OK. Lets talk about mahi mahi. What I would really like is for someone to
offer a solution to a worldwide inspection problem of scrombroid species. Tuna is
the number one consumed seafood in the world. It's a bit of a problem when
1000 tons are questionably tested as OK for import into the EU. And remember the
discussion started when an anonymous US buyer had 100% of his fresh tuna from
Ecuador mutilated by the FDA at the Fulton Fish Market.
I agree with what you say about mahi mahi and the local distribution chain. I
am trying to get people like yourself and Francisco to join in with this
discussion because this is a serious problem. From what I have seen first hand in
the past couple of years on the Indian, Atlantic and Pacific Oceans relative
to tuna handling and dockside sampling and evaluation we have a problem.
Just a reminder to sign your comments. It helps to attach the species to the
behavior.
Regards,
