the produce here is horrible
Produce in Argentina doesn't look good, like the oranges are not that ...orange... they have spots and so on. But at least they taste like oranges!
Rotten produce is a good sign for me...what's good for fungi and bacteria is surely good for me too (not so much pesticides, wax and other products to help the fruit look good).
When I lived abroad (mainly Europe) I noticed produce won't rot...it just gets dry with time. Exceptions are organic produce, which rot.
Carrefour is certainly NOT my first address when looking for fresh produce (supermarkets are not good for that either in Europe)
