It has been informed that millions of people ever year get infected by food-borne illnesses and according to a new report, it has been identified that which foods are most likely to make people sick.

There are three agencies that have worked to identify the food--Department of Agriculture, the US Centers for Disease Control and Prevention (CDC) and the US Food and Drug Administration (FDA).

These agencies have made use of a single method to measure food safety. It has been said that use of a single standard among agencies may help researchers measure the spread of disease in the US.

According to the researchers, they have examined records of 1,000 outbreaks of food-borne disease so that they can trace their source. They also studied reports of Listeria monocytogenes and Campylobacter.

About 17 classes of foods have been studied by the researchers. As per the researchers, salmonella was found to have spread among foods in eight food classes. It was found that salmonella infections spread through a wide variety of foods like chicken, pork and beef.

The researchers reached at the conclusion that more than 80% of all cases of one type of e-coli infections were associated to the vegetables grown in rows and consumption of beef. It was found that 50% of listeria cases spread through contaminated fruits. About 31% of illnesses are caused by bacteria carried through dairy products. Vegetables grown from seeds were also responsible for 18% of salmonella cases.

"These attribution estimates combined with additional data, can be used to inform agency priorities, support development of regulations and performance standards and measures, and conduct risk assessments, among other activities", said the Interagency Food Safety Analytics Collaboration officials.
