The highest levels were found after the bottles were heated, which the group said was done to simulate the effects on the plastic of parents' subjecting the containers to repeated high-temperature dish washing.
The plastic industry and major baby bottle makers insist that the small amount of bisphenol A leaching from bottles should not be a concern to parents, but Health Canada is currently reviewing the safety of the chemical, which has been tied by some researchers as a possible factor in the incidence diseases tied to sex hormone imbalances, including breast and prostate cancer.
Health Canada is also conducting tests on what it calls the ”migration rates” of BPA from baby bottles, but it has not publicly released its findings. It doesn't plan to do that until May, when it completes a safety assessment into the chemical and when it will announce whether it considers exposures from plastic bottles and other products are a threat.
Environmental Defence said that, based on its findings, parents should avoid polycarbonate plastic and shift to alternatives, such as glass bottles and plastics labelled BPA free.
”Any parent that is currently using these bottles should get rid of them immediately and spring for the $40 it will take to replace them all,” said Rick Smith, executive director of Environmental Defence.
He said parents typically have about four baby bottles, which cost about $10 each.

use of Bisphenol A in food and beverage containers immediately. Phase out
other uses over the next five years!
Bisphenol A is a hormone disruptor found in many everyday products including
food cans, plastic water containers and baby bottles. Studies show that people
can be exposed to Bisphenol A when it leaches out of these products. Low-
doses can harm our health.
