PCBs may also have other effects as well on
people as suggested by this following abstract.

Perhaps the man with the ear ring and the diamond
ear stud doing the Costco or Walmart checkout got too much
PCBs if you get my drift.

Effects of maternal exposure to a reconstituted mixture of
polychlorinated
biphenyls on sex-dependent behaviors and steroid hormone

In a previous experiment, maternal exposure to a polychlorinated
biphenyl (PCB)
mixture reconstituted according to the congener pattern found in human
breast
milk resulted in decreased aromatase activity in the brain of newborn
male rats,
together with feminization of sweet preference behavior in adult male
littermates. Both mixtures led to similar reductions of serum
testosterone and
testes weights. The purpose of the present study was (1) to examine
the
dose-response relationship for the reconstituted mixture and (2) to
study if the
rewarding properties of testosterone are affected at levels sufficient
to alter
sweet preference behavior. Female rats were fed diets with 0, 5, 20,
or 40 mg
PCBs/kg diet, resulting in an average daily intake of 0, 0.5, 2, or 4
mg/kg body
wt. Exposure started 50 days prior to mating and was continued until
birth of the
offspring. A dose-dependent elevation of sweet preference was found in
adult male
offspring, indicating feminization of this sexually dimorphic
behavior.
Examination of conditioned place preference revealed a preference for
the
testosterone-paired side at the highest exposure condition. In
weanling female
offspring, dose-dependent reductions of serum testosterone and
estradiol
concentrations were detected. In addition, testosterone concentrations
were
reduced in a dose-dependent manner in adult male littermates long
after
termination of exposure. PCB concentrations in adipose tissue from
offspring of
the low dose group (0.5 mg/kg body wt) were approximately 10 times
higher than
values at the upper margin of current human exposure. Taken together,
results
indicate long-lasting and dose-dependent changes in sex-dependent
behaviors and
levels of sex steroid hormones in rats following developmental
exposure to a PCB
mixture that resembles the breast milk pattern. ©2002 Elsevier Science

Always fun to see your ignorance on parade, Carole.  PCBs are not a
component of junk food, they're a variety of toxic chemicals (no
longer being produced in the US, by the way) that were used as
coolants and lubricants.
