Magnet 180x120Paediatric gastroenterologists and consumer advocates have asked for swift regulatory action that would ban the sale of high-powered magnets and stop new novelty high-powered magnet products from ever reaching the market, emphasising that strong regulations are the only effective way to prevent children from accidentally ingesting super strong, rare earth (or Neodymium) magnets.

In September 2012, the CPSC issued a notice of proposed rulemaking which would prohibit the sale of high-powered magnet sets (defined as aggregations of separable, permanent, magnetic objects intended or marketed by the manufacturer primarily as a manipulative or construction desk toy for general entertainment) if the magnet set contains a magnet that fits within the CPSC’s small parts cylinder and has a flux index (or strength) of more than 50.

The CPSC took this action in response to a growing number of documented pediatric ingestions of magnets from magnet sets. High-powered magnet sets, marketed under names such as Buckyballs and Zen Magnets, are comprised of tiny high-powered magnet balls or cubes, often with 200 or more magnets to a set.

"CFA strongly supports CPSC's determination that there is an unreasonable risk of injury associated with children ingesting high powered magnets," said Rachel Weintraub, Legislative Director and Senior Counsel at Consumer Federation of America.

"Data from CPSC and from pediatric gastroenterologists across the country documents the serious medical consequences that occur as a result of a child ingesting more than one high powered magnet. The unique properties of these magnets compel a regulatory solution such as the one CPSC has proposed, that would protect children from the severe consequences of ingesting more than one of these magnets."

Unreasonable risk of injury
High-powered magnets are not like other small foreign objects that children typically swallow. According to a 2012 study by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN), nearly 80% of high-powered magnet ingestions cases require endoscopic and/or surgical intervention. Comparatively, only 10 to 20% of other foreign body ingestions require endoscopic removal and less than 1% require surgery.

“Actions taken to date by the Commission appropriately reflect the risk of significant and life-threatening injury that these magnet products pose to children," added Dr Athos Bousvaros, NASPGHAN president.

"There is nothing worse as a physician than treating a child with a preventable injury. High-powered magnet ingestions are 100 percent avoidable if they are not available, which means banning their sale and doing everything possible to remove products already sold from any environment where children live, visit, play or learn."

When more than two magnets are swallowed, their attractive force (flux) allows them to find each other across or between different segments of the bowel. For example, connections can occur between the stomach and the small intestine, between the small intestine and the colon, or across loops of bowel. When this happens, the result can bowel perforation, fistulization (unnatural connections of the bowel), or tissue death (necrosis).

The danger of these high-powered magnets are complicated by the difficultly of a timely diagnosis. Ingestion of magnets does not result in immediate symptoms; consequently, there can be marked delay in diagnosis and treatment, particularly when ingestion occurs in a toddler or child with a developmental or psychiatric disorder who cannot verbalize the ingestion.
