A device and method for the provision of antimicrobial activity and/or moisture protection for goods and other items prone to damage caused by microbes and/or water, such as, for example, foodstuffs and other putrescible items, pharmaceuticals and other medical/veterinary products, paper and paper/fibre-board products, timber and wood products, electrical/electronic devices, clothes and fabrics, is disclosed. The device and method is particularly suitable for use with such goods and other items when contained within storage spaces (eg a package, refrigerator, wardrobe or shipping container). The device comprises a vapour-permeable container housing a moisture-removing material and an antimicrobial vapour-generating material in an arrangement such that water added to the device or absorption and/or adsorption of water vapour by the moisture-removing material causes the antimicrobial vapour-generating material to generate an antimicrobial vapour. A device and method for disinfecting items such as food containers and food preparation implements, is also disclosed.
