Perdue in regards to chicken does have a reputation for being among the producers with the least contaminants.
Personally, I stray away from anything that says Tyson on it.
As far as chicken goes, I prefer Bell Evans. Don't know if it's available down there.

Tomatoes here this time of year are around $2.99 a lb.
Yes, I have also tried the "ugly tomatoes" and they are even more.
I don't make sauce or the like but like a nice juicy tomato in my salad or on my sandwich. I even used to enjoy
eating them plain with a dash of salt.....if only I could find one that tasted like a tomato

As far as Chilean Sea Bass and Salmon. If you were to do a bit of research you would find that regardless of how reputable the so called source (in this case Wal Mart ) there are so many things that are misrepresented as being Chilean same as all Sole seems to come from Dover.
Salmon is another story with varieties from farm grown to wild, Prices can run from pennies to a fortune

I'll stick with my Servuga Caviar and cucumber sandwiches
