What is raw milk cheese?
Raw milk cheese is cheese made from milk that has not been pasteurized, a heating process that removes disease-causing germs, according to the FDA.
Consuming raw milk can cause lead to serious health risks, especially for groups like children under 5, adults over 65, pregnant women and people with weakened immune systems.
While most dairy products sold in the US contain pasteurized milk, some consumers opt for raw milk products because its advocates argue it contains beneficial bacteria, which the FDA has refuted.
