A device is disclosed for determining the possible presence of contamination of a container with a decorative exterior, for instance provided with a labelling and/or relief patterns, for liquids such as a drink such as beer or a soft drink. The device includes an irradiating device for irradiating the container with at least a first wavelength (for instance visible light, infrared, ultraviolet, x-radiation), and a recording device for recording a radiation sample of radiation after it has had interaction with at least a part of the container. Further, an orientation determining device is included for determining the orientation of the container relative to the recording device, along with a comparing device for comparing the sample to a reference matching the orientation of the container relative to the recording device during the recording to determine the possible presence of contamination.
