Is it true that breast milk can contain harmful man-made chemicals?
Yes, human breast milk may contain harmful artificial chemicals. The same is true of cow’s milk (and any mammalian milk, including whale’s milk, but I assume you’re most interested in milks that humans consume). Of great concern are not just agricultural chemicals showing up in cow’s milk (from fertilizers, etc.) but also chemicals meant to benefit the cows which aren’t good for humans (and probably not for calves, either): antibiotics and synthetic hormones (artificial hormones). You’ve already been given good instructions on how to find the research on this — I just wanted to add the point above, and to mention that breast milk also contains chemicals that are not necessarily harmful. For instance, eating garlic will change the taste of a woman’s breast milk. Hope this helps…
