If the ground beef is cooked and the recipe calls for it to be drained, rinsing the beef can help remove excess fat and grease. However, if you’re using lean ground beef (90% lean or higher), rinsing may not be necessary as there won’t be much fat to drain.
On the other hand, if you’re using raw ground beef, it is not recommended to rinse it as this can increase the risk of spreading harmful bacteria such as E. coli and Salmonella. Instead, it is important to cook ground beef thoroughly to a temperature of 160°F (71°C) to ensure that any harmful bacteria are destroyed.
In summary, if the recipe calls for the beef to be drained after cooking, you can rinse it. But if you’re using raw ground beef, it is not recommended to rinse it.
