Army Food Serves Environmental ResearchSymposium Highlights
One problem in measuring toxic pollutants is the difficulty in assessing whether levels are increasing or decreasing over time. Tests in the environment can be carried out, for example, by analysing core samples containing sediments. But to establish the intake via our food has been difficult. Now, researcher Dwain Winters at the US Environmental Protection Agency has found an interesting solution.
He has analysed dioxins and PCBs in meat from almost the entire century, by locating old army food parcels. The oldest sample is a 1908 "Emergency Ration" of beef and ground wheat, one of the first tinned foods available. A total of 14 samples from beef, pork, chicken and a type of bacon snack were taken. The results show that concentrations in food closely follow the development of levels in the environment, with increases until the end of the l960s, when they reached their peak. After that dioxins and PCBs in food have decreased.
