How serious is the food ban in Japan?

The economy of agriculture, in the areas affected directly by the radioactive food ban (Fukushima & Ibaraki Prefectures), is being hit hard.

One dairy farmer has dumped at least  3.5 tons of milk.

Spinach and Parsley farmers, who’ve spent 25 years or more growing their crops, have to let this year’s crops die, and maybe bury them.  No one has told them what to do with the contaminated crops, and, no one told them if they will be financially compensated for their loss.  One farmers says 30,000 of his Spinach plants will be lost because of the nuclear disaster.
