Is beef brisket safe to eat when its red still?

Yes, beef brisket can be safe to eat even if it's still red, as the color alone does not indicate doneness. The key factor is the internal temperature; brisket should reach at least 195°F to 205°F for optimal tenderness and safety. Additionally, the pink or red color can be a result of the meat's myoglobin, which can remain even when fully cooked. Always use a meat thermometer to ensure proper cooking.
