Assistant Professor

Andrea Etter is an assistant professor of food safety in the Nutrition and Food Sciences Department at UVM. She studies bacterial food safety with an emphasis on understanding the intrinsic bacterial factors which contribute to foodborne outbreaks of salmonellosis and listeriosis. Having grown up on a small homestead in the Midwest, she is also interested in how to communicate food safety better to small farmers, homesteaders, and fans of the rural lifestyle. In her free time she enjoys hiking, skiing, horseback riding, and fiber arts.
