Study: Cow, Goat and Human Breast Milk Can Contain up to 20 Chemicals

They say milk does a body good, but did you know a glass of the white stuff can contain up to 20 drugs and chemicals that are common in medicine, in addition to hormones? This goes for milk across the board – a study in Spain and Morocco on cow, goat and human breast milk has revealed the presence of a laundry list of foreign chemicals, though cow milk had far and away the largest concentration of chemicals. Using highly sensitive testing, the scientists’ research has proven the presence of synthetic chemicals in varying levels of the food chain – both in the breast milk we produce and the other types of milk we consume.

Does this study make you think twice about giving your kids milk?

  • 16 Votes Yes. I'm going to switch to soy or other non-animal milk.
  • 51 Votes No. I still think that milk's nutritional benefits outweigh the findings of this study.

Researchers from the University of Jaen purchased 20 types of milk, in Spain and Morocco for the study. Of the tested milks, cow’s milk had the highest dosage of chemicals. Drugs such as niflumic acid, mefenamic acid and ketoprofen – all anti-inflammatory drugs found in common pain killers – were present in the milk. A form of estrogen, called 17-beta-estradiol, was also present, although only in three millionths of a gram per every kilogram. The origination of these drugs is thought to be from growth drugs given to the cattle or from contaminated cattle feed.

Other chemicals found in the milks tested were the antibiotic florfenicol, and a steroid hormone called 17a- ethinylestradiol.

True, the doses of each chemical is miniscule, but their very presence is alarming, and proves the fluidity of these medications and chemicals in our food chain. The research does, however, provide a way to test these almost undetectable toxins. In the future, the testing could be employed to check the safety of other foods, possibly stopping the chain of chemical contamination at the source.

Makes you think twice about the whole ‘Milk does a body good’ thing, right?

    this makes me question conventional farming practices. Organic milk doesn’t have all that crap in it. We are what we eat, and so are cows. We can’t feed the cows garbage and expect to get a healthy product from them.

    This study is a bit misleading, appearing to reference the high levels of chemicals found in our current food chain, a result of our chemical safety laws in what we come into contact with, and the conventional food system which feeds chemical laden products to the animals we get milk from, and the massive over use of antibiotics and hormones used. It’s not the product that the problem, it’s us. Farm fresh milk that allow the animals to graze on open pastures I would venture to say would have a much lower incidence of these chemicals and hormones, as I would venture to say that mothers who try their darndest to avoid the chemicals in our system and don’t use hormones and antibiotics would have a much lower incidence in breast milk, as difficult as that is in ‘conventional’ living today. In effect, saying the product is the problem is an in admission of the underlying conditions that CAUSED the problem, rather than pointing to the resulting effects of our accepted systems that MUST be changed, since I’m quite sure similar tests on ANY food products would show similar results, since they are all at the mercy of ‘what we do.’ Also, in regards to the question asked about changing to soy milk as a result of the study (a huge leap from the real solution of obtaining fresh healthy products) is NOT an alternative.. Soy contains toxic compounds which is why even in Asia they are eaten in moderation (even when fermented) and also eaten with other foods which negate the negative effects of the antigens found there. The estrogen mimicers in soy can be dangerous to development, not even including the fact that almost all soy has now been contaminated by the GMO’s which predominate the sytem, and as such contain the toxic compounds of the organisms used to modify them, either by containing toxic BT poisons or unknown bacteria inserted into e. Coli cells. Looking at all the sides of a situation is very important when addressing this issue, and should not be taken as a one size fits all problem or solution. I wish much love to all. Best
