the real question is why not

Carrots and boar can be farmed at Black Forest level
Turnips can be farmed at Swamp
Wolves and onions can be farmed at mountain
Barley and lox can be farmed in plains
Magecaps and jotun puffs can be farmed in mistlands

The answer seems to be because eitr was just introduced in mistlands.

The real question should be why can't we farm seekers!? :-)
