Over the next few years scientists will be able to evaluate the efficacy of this treatment for reducing tick populations. This technology could then be used in widespread efforts to thwart the spread of Lyme disease. For further information on the four poster and other research on the control of Lyme disease, contact Drs. John Carroll, Pat Allen, or Dolores Hill. Preharvest Food Safety Foodborne pathogens are getting increased attention due to greater consumer awareness and the presence of emerging pathogens in foods.
Contamination can occur at any point in the food chain including on the farm.
In the Parasite Biology and Epidemiology Laboratory, scientists are determining risk factors associated with two important parasites of pigs, Trichinella spiralis and Toxoplasma gondii . Trichinella causes trichinellosis in humans and is acquired by eating raw or under cooked pork containing infective stages. Fortunately, this parasite is found only rarely in U.S. pigs. It poses a risk to pregnant women and to persons with depressed immune systems. By knowing how pigs become exposed to these parasites, it is possible to develop management strategies to greatly reduce of eliminate risk of pig infection and thereby prevent risk to human health.
