Department of Agriculture (USDA) Agricultural Marketing Service (AMS) specialists demonstrate egg candling, with a simulated blood in the egg, as one of the many ways that food is graded, during 4th USA Science & Engineering Festival at the Walter E. Washington Convention Center, in Washington , on Saturday, April 16, 2016. Candling refers to the candle light that was once used to see the shadow of red blood in an egg. Hand candling—holding a shell egg directly in front of a light source—is done to spot check and determine accuracy in grading. Advanced technology, utilizing compute
Department of Agriculture (USDA) Agricultural Marketing Service (AMS) specialists demonstrate egg candling, with a simulated blood in the egg, as one of the many ways that food is graded, during 4th USA Science & Engineering Festival at the Walter E. Washington Convention Center, in Washington , on Saturday, April 16, 2016. Candling refers to the candle light that was once used to see the shadow of red blood in an egg. Hand candling—holding a shell egg directly in front of a light source—is done to spot check and determine accuracy in grading. Advanced technology, utilizing computerized integrated cameras and sound wave technology, is also being applied for the segregation of eggs. USDA is a sponsor of and exhibitor at USASEF. Multiple USDA agencies including National Institute of Food and Agriculture (NIFA), Forest Service (FS), Agricultural Research Service (ARS), Food Safety and Inspection Service (FSIS), Natural Resources Conservation Services (NRCS), Food and Nutrition Service (FNS) and Animal and Plant Health Inspection Service (APHIS), Grain Inspection, Packers and Stockyards Administration (GIPSA) will be participating in this event. The USA Science & Engineering Festival is a national grassroots effort to advance STEM education and inspire the next generation of scientists and engineers.
