>"And where mother's milk has many advantages for immunity, etc, it is as contaminated as everything else."
Agreed, you can find most any toxic compound in milk (from a cow or a countess). While not true in the developed world, the immunity benefits of breastfeeding are so great that in Africa it is recommended that mothers KNOWN TO HAVE HIV breastfeed because the risks of HIV transmission in mother's milk is less than the risk of dying of diarrheal illness.
As a 50-year-old male, I'm less concerned about my low BPA exposures, some of which are almost unavoidable (if you eat in restaurants or otherwise use canned foods or drinks), than I would be for a gestating or lactating woman. But again, I look for ways to reduce those exposures without getting all worked up over it.
