New tests find BPA in kids' food containers

Wed. May. 28 2008 News Staff

A controversial chemical that Health Canada is moving to ban in baby bottles has turned up in tests conducted on cans for foods commonly served to Canadian children.

Tests conducted on the food cans for CTV News and The Globe and Mail shows similar or higher levels of bisphenol A than in baby bottles.

While baby bottles leach about 6 parts per billion of bisphenol A (BPA), the exclusive tests of food cans show:

* A can of children's ravioli leached 6 parts per billion.
* A can of peas and carrots leached 7 parts per billion.
* A can of tomato juice leached 14 parts per billion.

In this study, the first of its kind in Canada, the method of testing used most closely mimics the canning process. Fourteen cans of popular Canadian foods were sent to XenoAnalytical LLC, a laboratory in Columbia, Mo . The cans were emptied of food and rinsed five times before being filled with water and heated for 24 hours at 95 C.

(The food itself from each can could not be accurately tested because other chemicals in the food could interfere with measuring the BPA.)

Studies have shown when cans are heated in the manufacturing process, BPA leaches out of the linings. Foods are first sealed in cans and heated to kill bacteria in the food. Cans are heated to temperatures between 116 C and 121 C, and the length of time varies according to the type of food.

"The tests we did in the cans are fairly conservative," said Julia Taylor, the lab technician that conducted the tests.

"We used water, which is less likely to pull out BPA in a can."

Because these findings show that BPA leached out of the cans and into water, it can be assumed that the chemical is leaching into the food itself when the cans are heated during the pasteurization process, Taylor said.

Environmental Defence, an advocacy group that has long called for a ban on BPA, conducted its own study into BPA levels in plastic baby bottles. It found that many of the bottles, manufactured by popular name brand companies, leached from five to eight parts of BPA per billion when heated.

Rick Smith, the executive director of Environmental Defence, finds these new results troubling.

Yep, scary!

I replaced my kids bottles, and we're replacing other containters/plates/cups etc as well.

We got our stuff at an online store which sells BPA free stuff. Give 'em a try if you're looking to replace yours:

Good luck and keep us ALL safe!
