Urgent Help: 7 week infant drank spoiled formula

My 7 week old infant drank 20 ml of spoiled formula that has been sitting on the table for 6 hours. I tasted it and realized it was bad after 20 mls. Help. I’m panicking. Don’t know what to do. Now feeding him 90 mls or Breasf milk. Should I have made him throw up whatever in his stomach? Did your LOs ear spoiled formula and was fine? If not what happened? Help please.
