Currently, Vietnamese agricultural products are accounting for a high proportion and hold a key position in the industry. According to the assessment of the Ministry of Agriculture and Rural Development, due to the impact of the Covid-19 pandemic, the total import and export turnover of Agriculture, Forestry and Fisheries in the first 6 months of 2021 still grew well.
However, before agricultural products are brought to circulation on the road, they must be preserved in the storage system. Agricultural products are often penetrated by mold, termites, termites and microorganisms during the time of not storing the goods. Therefore, the problem is that there is a need for a method to prevent and minimize the impact of pathogenic microorganisms on the circulation of agricultural products in order to help agricultural products achieve the highest quality, not only meeting domestic standards but also export requirements. In this article, IFC will provide a technical process for fumigation on agricultural products to answer the above questions for you and related readers.
However, before agricultural products are put on the market, they must be preserved in warehouses. Agricultural products are very susceptible to mold, termites, termites and insects during storage. Therefore, the problem is that there must be a method to handle and minimize the harmful effects of harmful organisms in the process of preserving agricultural products, helping to achieve the best quality agricultural products not only meet the domestic standards but also meet international requirements. In this article, IFC will provide a technical process for fumigation for agricultural products to answer these questions for businesses and interested readers.
Fumigation is a technical measure that uses substances capable of freezing or sublimating to destroy harmful microorganisms in a closed environment according to regulations.
Why does each shipment have to be fumigated?
According to the requirements of the phytosanitary authorities in the exporting and importing countries, goods in general, especially agricultural products, need to be fumigated before export to prevent the spread of harmful organisms. from one country to another as well as to ensure that the goods are not damaged in terms of weight and quality, in accordance with the provisions of each import and export commercial contract.
Prepare materials and equipment for fumigation:
Clean air sterilization
For fumigation by tarpaulin: move the tarpaulin from the top of the shipment and then continue to pull the tarpaulin to the sides to cover the entire shipment. Take a sandbag and cover it with a tarpaulin. If the floor of the warehouse or the place of fumigation is not guaranteed, cover the bottom of the counter with tarpaulin to limit the loss of medicine. Check the tightness of the tarpaulin, if it is punctured, it must be sealed with tape or kraft paper and glue.
For warehouse sterilization: use kraft paper and glue to seal the slots, crevices, ventilation doors. Stick the door on the door but leave one for the staff to take medicine. If the warehouse floor is not enough, it must be sealed with bricks, lime mortar or kraft paper and adhesive.
Sanitizing spray: spray cleaning around the disinfection shipment or around the warehouse area to limit the re-entry of insects from the outside after completion of disinfection (due to insects flying or moving out of the warehouse). outside the scope of sterilization during sterilization)
Discharge drug: when the sterilization time is up, proceed to withdraw the medicine (airy).
Time to disinfect with tarpaulin: the person performing the disinfection must have an anti-toxic mask to remove the sand snakes and then cover a part of the tarpaulin. After about 4 hours, test the Phosphine gas concentration inside the container. inside the shipment. If the concentration is below the allowable safe threshold, the staff will remove the tarpaulin, collect the drug residue and check the results.
For warehouse disinfection: the fumigation worker uses a knife to cut the paper and open the warehouse. After 4 hours, test the phosphine gas concentration in the warehouse. If the concentration is below the safe threshold, the drug residue will be collected and the results will be accepted.
Industrial dryers can be used to accelerate drug treatment.
Treatment of drug residues: After completion of the sterilization process, the drug residues will be collected and buried under the ground. Particularly for Aluminum phosphide in the residue, there is still 2% that cannot be decomposed, so it is necessary to treat the residue before burying. The drug residue is poured directly into a container containing a concentrated soap solution and then mixed well so that the drug is completely decomposed, the person in charge of handling must wear an anti-poison mask and protective eyewear.
Absolutely use soap to clean hands, feet or other parts of the body that come in contact with Phosphine or commercial drugs after sauna and before eating and drinking.
