Farms, market gardens, packaging units and companies that export plants and other agricultural products to the EU are required to register with the relevant authorities. This will enable them to obtain certification from district agriculture and forestry offices, according to a recent announcement by the Ministry of Agriculture and Forestry. Plants and agricultural products destined for export must also be examined for Maximum Residue Limits to ensure they do not exceed set standards. They also must not contain any microbes, especially Salmonella and Escherichia Coli , and be shipped with a laboratory test document that verifies them as being ISO 1725 certified. Before issuing phytosanitary certificates, the authorities will inspect and randomly collect samples from products to prevent infection, as specified by the European Union.
