Costco is facing a potentially damaging lawsuit over allegations its protein powder products contain high levels of toxic heavy metals – including lead, cadmium, and arsenic – which can pose serious health risks. The claims centre on Orgain Organic Protein Powder, marketed by Costco as "high quality, clean, and nutritious", but tested to contain concerning levels of these substances.
The lawsuit, filed in Washington state, highlights the potential dangers of heavy metal contamination in food products. Research suggests that prolonged exposure to even small amounts of these toxins can have long-term effects on our health, including damage to organs and an increased risk of chronic diseases like cancer. According to NHS guidelines, "high levels" of lead are considered to be 10mcg or more per litre of blood; in this case, Consumer Reports found that Orgain Organic Plant-Based Protein Powder Vanilla Bean exceeded its 'level of concern' for lead.
Consumer Reports last year investigated heavy metal contamination in protein products and found over two-thirds contained more lead per serving than experts deem safe for daily intake. While the lawsuit acknowledges some natural environmental substances can be present in plant-based ingredients, it argues Costco should have taken steps to detect and disclose any potential contaminants. The plaintiffs assert that typical consumers would be unable to test their food for heavy metals without expensive laboratory equipment.
In response to allegations, an Orgain spokesperson stated their products adhere to all applicable food safety standards and guidance. However, the lawsuit seeks a court order compelling Costco to disclose the presence and levels of heavy metals in its products, both online and in-store. The plaintiffs also aim to prevent the retailer from selling these products without adequate transparency about potential contamination.
