kidvilla said:thank you for the reply, as for the use of medroxyprogesterone,
I apologize if i didn't clarify that its use is not in beef, but rather used therapeutically in Mexico to assist children in reaching height (height therapies were an old obsession of mine), and were administered by a doctor to a young man in an effort to reduce serum androgens which have long been suspected of causing premature maturation/closure of the epiphyseal tissues, thus reducing a maturing adolescent's time in which he can grow.
the concerns with beef are so many that i could spend the next 50 megabytes writing on each of them, but a few of the endogenous hormones in use are for purposes as: (1)(2)
Fertility enhancement and improvement of in-vitro success
genetic manipulation of cattle in order to maximize natural marketable efficiency (designing cattle with more beef on them)
Production (milk) enhancement for maximum efficiency
metabolic agents to limit beef adipose production
antibiotics, antidiabetics, and other illness management drugs used to insure cattle utilization.
anabolic agents used to maximize feed efficiency
growth agents used to maximize cattle partitioning
of all of these, the ones which are suspected of growth retardation are growth agents (HGH), anabolic agents (steroids), metabolic agents (t3, clenbuterol), and production enhancers (igf1).
zearalenone, a fermentation estrogen (RALGROW) which binds to epyphesial tissues is suspected of slowing the growth process (3).
diethylstilbestrol (DES)(discontinued, but still ocasionally used) - an estrogen which is used to treat hormonal problems brought on by ovarial operations or misadministration of androgens, is highly suspect in premature epiphesial closure.
thyroprotein - used along with T4 and T3 to stimulate increased milk production. this protein increases somatotropins in milk (igf, gh) and also tends to taint the milk with trace amounts of triiodothyronine (t3) and thyroxine(t4).
melengestrol acetate (BOVATEC) - another estrogen-type feed enhancer which is commonly used to improve feed efficiency and prevent estrus in cattle. it increases serum androgens (kind of like reverse aromatization) and can be used as late as 48 hours prior to slaughter.
trenbolone acetate - our old friend fimaplix, im sure i don't need to explain the fact that androgens are well known for epyphesial maturation.
testosterones and their esters - again, well known to stunt growth.
now, the first thing to keep in mind is these substances exist in infinitesimal amounts, and typically, the FDA allows their use because studies (funded by the proponents) have shown that residues from these components are supposedly below any amounts which could collect in an average person. as for the fast-acting androgens, well this is why fina is so popular too (because it is supposed to clear the system quickly with no residues), but unfortunately, there is evidence that these androgens under many circumstances will not entirely clear the system. trenbolone alone is actually known to last 90-120 days (and typically, heifers are not alive that long after implantation)(5). the simple act of improperly implanting fina is known to increase residue(4) levels which its funny, but as long as the beef council tests it, it passes, but when independent studies test it, the numbers are always higher(6).
now i must point out, this is a hotly disputed item (the discussion of whether or not there are sufficient residues in meat to be a problem for humans) because every side comes up with its own proof that either there are, or there are not harmful residues....
kind of like the rBST controversy with milk, the dairy industry argues that rBST is not detectable in humans, yet time and again, serum IGF levels in humans are statistically higher in milk drinkers than non-milk drinkers(7)(8)
now the point here (before i digress too much) is:
1. that meat is known to contain androgens
2. the amount and residues of which are disputed
3. therapy to reduce the effects of these androgens is proving highly effective in negating the effects of these androgens (particularly the deleterious ones such as stunted growth).
now, as for the argument about the substances used to clean the devices in which infant formulas being within acceptable levels because of the fact they have been "proven" to be below toxic amounts is theoretically correct, and i cannot argue that. but my concern is that (and ask around), there will be times when you buy a t-shirt and put it on, and it itches the hell out of you. you wash it a few times and it will no longer itch. the idea here is that although the chemicals used to process our goods are supposed to be below toxic levels for residues, there are many times when these residues (either by human error, substitution, or downright criminal negligence by the manufacturers) will reach unhealthful or even toxic levels, and buying products which don't use these methods (if more effective and less toxic methods are available) seems to be a way of "playing it safe" and avoiding the possibility....

Where is your evidence of growth retardation from food? From my readings the final heights of individuals has been increasing for decades, due mainly to increased meat/fat consumption. I would be interested in seeing evidence that we are shrinking.
As for your assertions that meats contain "toxic" substances, and while they are in minute quantities, and MAY cause problems in SOME, why limit this idea of medical case anomalies to all foods? Do you realize that vegetables are vectors for disease at higher rates than meats? If one is to live their life fearful of anything that has been shown to, at one time or another, cause an undesirable effect in another, then they should essentially kill themselves.
The arguments of the vegans/anti-technology wackos is essentially the fear of knowledge and reason. They are essentially advocates of caveman mentality and because of this they react as a caveman in the presence of fire.
