The method and the apparatus are used for combatting germs on the surface of products, in particular on food products. The apparatus employs a combination of steam and ultrasound to kill germs on the surface of a product (8), which is conveyed past a steam device (1). The pressurized steam is fed through a steam passage (3) to an opening (2), conveying the steam to a cavity (4) in which the steamis made to oscillate at an ultrasonic frequency. The oscillations in the steam prevent from heating the products excessively, while germs present on the surface of the products are heated and killed.
