Pickled onions

[lindyloo57]

After opening and kept in fridge, how long can you keep pickled onions and red beetroot, on both jars it say to eat within 4 weeks of opening,

Forever!
I keep pickles for months and they're fine, pickling preserves them.

I'm not sure I understand the question?!? Surely if you have a nibble every time you open the fridge they're gone in days???

Ihavebrillohair, why do you think it says eat after 4 weeks of opening,
