To improve global food security, it is also important to study food post-harvest. Bacterial contamination of animal products leaves many people hungry worldwide. Animal scientists are studying ways to track and prevent microbes like Bacillus that curdle milk or the gram-negative bacteria that cause meat to spoil.
“The loss of meat is a consequence of the growth of gram-negative rods,” said Kathryn Boor, professor of food science and dean of the College of Agriculture and Life Sciences at Cornell University.
Boor worries that animal producers in developing countries do not have the resources to keep the food supply safe from pathogens. Boor said better education and access to technology could lead to “really good sanitation in the food-handling chain.”
