Is Free-Range Better (For You or the Pig)?

[1]Free-range pork may not be all it's cracked up to be.
IS free-range pork better and safer to eat than conventional pork?
Many consumers think so. The well-publicized horrors of intensive
pig farming have fostered the widespread assumption that, as one
purveyor of free-range meats put it, �the health benefits are
indisputable.� However, as yet another reminder that culinary
wisdom is never conventional, scientists have found that free-range
pork can be more likely than caged pork to carry dangerous bacteria
and parasites. It�s not only pistachios and 50-pound tubs of peanut
paste that have been infected with salmonella but also 500-pound
pigs allowed to root and to roam pastures happily before butting
heads with a bolt gun.
