In the United States, in the 1830s and 1840s, what was a widespread view as regards fresh fruit and vegetables?
Answer: That they were dangerous to health, and especially harmful to children. Doubts as to the cause of cholera, typhoid, dysentery and other epidemic diseases, made these fears more believable. Within half a century, however, the US had organised a nation-wide, soon to be international, trade in fresh fruits and vegetables.
