More and more local small farms are popping_up in opposition to factory farms.
Today's commercial farms do not fit the image that comes to mind while happily singing along to Old MacDonald. Instead,
most
of the
nation's
food
comes from
CAFOs, Concentrated Animal Feeding Operations, where animals are
kept in tightly enclosed conditions as they are fattened up and
readied to be killed for food.
Fortunately, knowing exactly where one's food comes from
has led to an increase in the availability of what is known as
“grassfed” beef.
Technically, all cattle are grassfed for at
least a limited amount of time,
but what makes the meat
significant is that it is grassfinished, not forcefed corn, soy or
grains. This change in diet makes all the difference since corn is
not part of the cow's traditional diet, and therefore causes major health issues for it. To deal with the health issues, antibiotics (抗生素) are used and some of the antibiotics used to treat the cattle
are similar to those given to humans, so they can decrease the
effectiveness of medicine when a consumer is sick.
