All countries maintain measures to ensure that food is safe for consumers and to prevent the spread of pests or diseases among the population, animals and plants. The name of these measures is Sanitary and Phytosanitary Measures (SPS). They can take many forms, such as requiring products to come from a disease-free area, inspection of products, specific treatment or processing of products, setting of allowable maximum levels of pesticide residues or permitted use of only certain additives in food... They apply to domestically produced food as well as to products coming from other countries.
