Thanks for copying responses to me and/or to Bill holden from Alatini

> Our snapper fillet and tuna loin process is the same:
> * fillets and loins are taken off fresh fish and put into a tub with
> ice.
> * this goes to the area where we vacuum pack and they are put into
> plastic bags, put into the machine and vacuumed.
> * these are then put into a blast freezer to be frozen as that is how
> we sell them locally
>
> Problems:
> * the snapper fillets when removed from the vacuum machine. An off
> white yellowish/brown fluid is trapped in the bag with the fillet.
> Remember these are fresh fillets going in.
> * When our customers have been bringing the fillets back, they have
> the same complaint. Upon opening the bag the fish smells 'off' or 'old'.
> Also the fillets have a slimy feel on the surface. If the fish is rinsed
> the smell and slime feel go away, but you know how first impressions are!
> * with the tuna loins. I did not see them immediately after vacuuming
> but a few days later the loin (yellowfin) was most definately BROWN!
