Consumers typically pay more for organic pork, primarily because organic pork costs more to produce. This increased price tag is at least partially due to lower feed efficiency and higher feed costs in organic production, Honeyman said. As of early May, the price of organic corn is around $8 per bushel, compared with the price of traditional corn at around $3.50 per bushel.
