A leakage detection patch ( 10 ) for a modified atmosphere package comprises a substrate ( 12 ) and an oxygen sensing spot ( 14 ) arranged thereon. The oxygen sensing spot contains an oxygen indicator, which may be interrogated remotely An adhesive strip ( 16 ) for fixing the leakage detection patch to a package surface of the 5 modified atmosphere package extends peripherally around the sensing spot. The leakage detection patch further comprises means ( 20 ) enabling oxygen diffusion between the modified atmosphere and the oxygen sensing spot.
