Leafy Green Lettuce and Petri Dish Analysis

A gloved hand carefully holds a petri dish with small green colonies growing inside, with a head of lettuce behind it. Taken in bright, even lighting, this close-up composition highlights elements of analysis and food science. This image can be used for projects about foodborne illness, testing, food safety, agriculture, and biology. The green lettuce is a refreshing background to the lab work being performed.
