I’m linking this article here since it has Canada specific information.

How is this regulated in Canada?

The Canadian Food Inspection Agency said in an email that it is responsible for the surveillance of chemical residues in foods and how they follow Canadian regulations, while Health Canada sets the maximum level for environmental and industrial pollutants in food.

However, it’s not clear whether these protein products are regulated as food or natural health products, and Health Canada could not respond to CBC’s questions by deadline.

Goodridge wants to see Health Canada set guidelines for these protein powders or dietary supplements, he said.

“There are no specific federal limits for lead in protein powders or dietary supplements,” Goodridge said. “This, in my opinion, is a big regulatory gap.”

    I wonder if the chocolate ones are from sourcing from counties using leaded gasoline, or used it more recently than countries that stopped.

    This was an issue decades ago since farms in countries had old cars that still required leaded fuel for lubricating valves etc and that fall out landed on crops.

      From my interpretation of looking around a bit on the topic of lead in food and especially supplements. There definitely a decent amount of companies that don’t seem to care enough to know.

      Some companies could go from low to high heavy metal contents and for them it’s luck of the draw since they aren’t that on top of things.

      We really need a proper regulatory network for these things.

      I thought the lubricating valves thing about leaded was a myth. Sunshine just posted about it yesterday

        Hmm, maybe. Original purpose was higher octane to prevent engine pre ignition, but I thought added affect was valve slide lube

          Aviation fuel (like personal sized planes) is still leaded because it makes the engine more reliable.
