If uncooked hamburger is brown it safe to eat?

It is not necessarily safe to eat uncooked hamburger regardless of its color. Uncooked hamburger can be contaminated with harmful bacteria, such as E. coli and Salmonella, which can cause foodborne illnesses.

The internal color of raw ground beef is not a reliable indicator of its safety or doneness. In fact, the color of raw ground beef can vary from pink to brown depending on the way it has been stored, handled, and processed.

Ground beef should always be cooked to an internal temperature of 160°F (71°C) to ensure the destruction of harmful bacteria and to make it safe for consumption. Using a meat thermometer is the most accurate way to determine the internal temperature of ground beef.
