No Attie, they are always fresh oysters that I eat/use for biz or personal consumption.
There was recently a HUGE scandal in lil ole' NZ during the visiting Irish Rugby teams match with the Allblacks. Apparently, the stadium caterers staff had forgotten to order the 100's of dozen local fresh oysters required for the corporate boxes so had to have a hasty rethink!! Bad move. They chose imported Korean ( Im sure they said that) oysters but neglected to read the disclaimer on the packaging ( its bad enough they were frozen when the punters expected/wanted fresh!!) which stated that the oysters MUST only be eaten cooked.
So....long story short, punters ate raw oysters from Korea, meant to be cooked because, as we have found out, they can contain some wee nasty bug as they are harvested near an open sewer area.
AN OPEN SEWER AREA???? And we are importing them?? Dear Lord.
Needless to say, it made national news when many high fliers got VERY ill and that Caterer's biz, obviously, is in trouble. Bad judgment/bad oysters/sick punters.
For me, if I cant get local fresh, I dont have them on my menu.
BTW anyone reading this...our Government is now looking more closely at banning these products. So much for Clean Green New Zealand at times like this. Its embarrassing.
