This month in EHP
This month’s feature stories in Environmental Health Perspectives (EHP) (http://ehp.niehs.nih.gov/) explore questions surrounding human risk for Lyme disease and the safety of food additives.
The Lyme Disease Debate: Host Biodiversity and Human Disease Risk
Thirty years after its discovery in the northeastern United States, Lyme disease is the most common vector borne infection in North America. The causative agent, the spirochete Borrelia burgdorferi (Bb), was first isolated from ticks collected in the woodlands of New York. Today, the ecology of Bb is the subject of both intense study and intense scientific debate. Some researchers think protecting large tracts of forest habitat will ultimately reduce the risk of human infection. Others believe the relationship between host biodiversity and human disease risk is not so clear cut.
Food Additives: A Primer
Food additives include all the substances present in a food, from the basic ingredients to those added unintentionally through processing, storage, and packaging. Under current U.S. law, companies can use food additives without U.S. Food and Drug Administration (FDA) premarket approval, as long as the additive is what the agency considers to be generally recognized as safe, or GRAS. This article explores what’s involved in earning a GRAS designation from the FDA.
