Safety regulations for iodine use are established to minimize the risk of toxicity. These regulations include guidelines for the safe use of iodized salt, limits on iodine content in dietary supplements, and protocols for the handling of iodine in industrial and medical settings. Organizations such as the World Health Organization (WHO) provide recommendations to ensure safe iodine levels in the population. Toxicologists play a key role in developing and enforcing these regulations to protect public health.
