testing of samples to assure safety. As has been seen in the large scale recalls of 2007, sample testing can miss non-conforming product. A design may be conceptually safe, but without control of the production, the design may not be met by the manufacturer. Similarly, the applicable toy safety standards to which a toy is tested by a laboratory may not discover a hazard in a product: in the case of 2007's magnetic toy recalls and the Bindeez recall, the products in question met the requirements laid down in the applicable safety standard, yet were found to present an inherent risk. Proposed process and quality control standards, similar to the ISO 9000 systems, seek to eliminate production errors and control materials to avoid deviation from the design. The creation of manufacturing quality standards for toys will help ensure consistency of production. Using a continual improvement model, production can be subject to constant scrutiny, rather than assuming the compliance of all production by testing random samples. In October and November 2007, mandatory third party testing by companies such as LGA, Eurofins, Bureau Veritas or SGS Consumer Testing Services was proposed by regulators in the EU and US, to a (possibly new) international standard, requiring a new safety mark. There is no indication that the proposals will address manufacturing control. Product recalls and safety hazards The ability to recall a product from the market is a necessary part of any safety legislation. If existing quality and safety checks fail to detect an issue prior to sale, a systematic method of notifying the public and removing potentially hazardous products from the market is needed. Some toys have been discovered to have been unsafe after they have been placed on the market. Before the introduction of safety monitoring organisations the toys were simply stopped being manufactured if any action was taken at all, but since then there have been many toys that have been recalled by their manufacturer. In some notable cases the problem has only been found after the injury or even death of a person that purchased the product. Choking is the number one reason for accidents, but chemicals such as lead can also cause developmental problems like behavioral disorders and sickness. Exposure to lead can affect almost every organ and system in the human body, especially the central nervous system. Lead is especially toxic to the brains of young children. In
