Health Canada's sampling and evaluation program has determined that the Borax powder packet provided with Slime Smoothies’ slimes do not meet the Canadian toy safety requirements related to boric acid content. Boric acid can be toxic to children if licked or swallowed. Children are more sensitive to boric acid toxicity than adults. High levels of boric acid ingestion may have long-term effects on a child's development and their future reproductive health. As of October 16, 2023, the company has received no reports of incidents or injuries in Canada.
