The present invention relates to combinations of zinc pyrithione and food-approved antimicrobials which provide a synergistic antimicrobial effect. The food approved antimicrobials are selected from sodium sulfite, sodium bisulfite, potassium metabisulfite, potassium sulfite, calcium sulfite, calcium hydrogen sulfite, potassium hydrogen sulfite, sodium nitrate, potassium nitrate, and lysozyme. These combinations are useful for the protection of any living or non-living material, such as food, crops, plants, fruits, wood, wood products, leather, natural or synthetic textile, fibers, non-wovens, technical textile, plasticized materials and non-plasticized thermoplastics as polypropylene, polyvinylchloride, etc. . . . , paper, wall paper, insulation material, laminates, amino moulding compounds, paints and coatings, fabrics, floor coverings, synthetic fibres like plasticized polymers, hessian, rope and cordage and other biodegradable materials against deterioration due to the action of microorganisms such as bacteria, fungi, yeasts, algae, and the like. Also, the present invention relates to compositions comprising a combination of zinc pyrithione and said food-approved antimicrobials; in respective proportions to provide a synergistic antimicrobial effect.
