Russel, here is what I was referring to earlier about
a compound (PBB) inadvertantly being added to cattle
feed - which then made it into the food chain.

I think we have far more to fear from conventional human
mistakes, than GeneEng'd food sources, but, that is no
reason to halt scientific study in that area.

Researchers in the US have found that exposure to Polybrominated Biphenyls
(PBBs) may cause an increased risk of cancer to the digestive and lymph
systems.

The study looked at the incidence of cancer in individuals exposed to PBBs
after a 1973 food contamination incident in the state of Michigan, in which
1 ton of PBB fire retardant was added to cattle feed by mistake, thus
contaminating the animal and human food chain.

Approximately nine million people were affected. Some 25 years later, in a
study published in 1998, researchers found that humans in the group with the
highest exposure to the contamination were 23 times more likely to develop
digestive cancers, including stomach, pancreas and liver cancers.
Preliminary results also found a 49-fold increase in lymph cancers.

b) Poisoning

Bulk production by industrial farming scales up the risk of food poisoning,
and introduces new risks. In 1973 a Michigan factory which produced both
fire-retardant (poison) and animal feed, got the two mixed. The poison was
sent out to hundreds of farms and used unsuspectingly. When cattle started
dying the cause was not traced for some time: animals slaughtered were
converted into feed which affected healthy animals: meanwhile infected meat,
eggs, and milk were sold, and thousands of chickens which had inexplicably
stopped laying were sold to an international soup company. The poison (for
which there was no known antidote) was chemically akin to one which causes
cancer and genetic defects (Observer 5 Dec 1976).

Chemical of the Month Carcinogen Profile: Polybrominated Biphenyls (PBBs)

http://www.prop65news.com/pubs/p65news/issues/9409/940909.html

A PBB-containing commercial product, FireMaster FF-1, was mistaken as the
feed supplement magnesium oxide. Initially, health problems in dairy cattle
indicated a poisoning, but several months passed before PBBs were identified
as the problem. Following the establishment of a Michigan Department of
Agriculture (MDA) farm animal testing and quarantining program, over 30,000
cattle, 2,000 swine, 400 sheep and 2,000,000 chickens exceeding PBB
tolerances were destroyed (MDA meat fat 0.02 ppm, FDA milk 1 ppm, FDA 0.1
ppm eggs). During the nine months between the initial accident, detection,
PBB identification, animal testing, and quarantines, PBB contaminated food
products were consumed by producers and consumers. Epidemiological studies
targeting the exposed population continue in order to evaluate long- term
risks.
