A new study indicates that detectable levels of dog and cat allergens—in
amounts sufficient to increase the risk of allergic sensitization—are
present in all US homes, including those without pets.
Scientists at organizations including the National Institute of Environmental
Health Sciences, in Research Triangle Park, NC, found considerably higher
levels of allergens in homes with an indoor dog or cat. But levels that could
increase the risk of allergic sensitization were also found in homes without
these animals (J Allergy Clin Immunol. 2004;114:111-117).
