Allergic reactions to peanuts cause around 500 hospitalizations and even some deaths in the United States each year. … Accidentally ingesting as little as a third of a single peanut — about 70 milligrams — can send someone to the emergency room, and some people may react to only 1 milligram….
A number of other teams have … tried various ways to make peanuts less lethal. A 2008 study led by a U.S.D.A. scientist showed that the shocks produced by pulsed ultraviolet light significantly reduced the allergenicity of peanut extracts in a lab test. Researchers in China have tried irradiating peanut extracts with gamma rays to make them less allergenic.
Improvements in genetic-engineering tools have given molecular biologists the means to stop the peanut plant from producing some of the allergenic proteins in the first place. … [O]nce allergenic genes are silenced, they stay that way through multiple generations of the peanut plant …
The scientists bioengineering peanuts to lack allergens are hoping to eliminate genes from the final product, rather than introduce any new ones.
[T]he goal of preventing accidental deaths by replacing peanuts for the general population with a safer version becomes ever more elusive as scientists discover more about how much the nature and strength of peanut allergy can vary from one individual to the next.
