hi all

I live on a small main road and have wild blackberries
in the front garden (about 30 foot from road)

would these be bad/dangerous to eat
(after thorough washing obviously)

I would never pick blackberries from a roadside, not because of animal
contamination but because of deposits from exhausts. They're not water
soluble so can't be washed off. the distance you state should be
enough barrier to prevent most of that.

I would be interested to know just what deposits you would expect? Unleaded
fuels have removed the nastiest one, and catalytic converters remove most of
the gases. Diesels are chucking out particulates, but they are mostly
carbon. I'm not suggesting that you are wrong - I wouldn't eat blackberries
from the side of the road either, but I'd really like to know which deposits
you are thinking of.
