On July 25, authorities in Da Lat city, Vietnam, temporarily detained a shipment of 29 tons of Chinese potatoes and onions due to missing documentation and concerns about pesticide residues. The driver of the potatoes, Le Anh Nhat, was found to have an expired SARS-CoV-2 test certificate and was isolated. This incident is part of a larger issue where hundreds of tons of Chinese potatoes have been imported to Da Lat, leading to concerns about the reputation of local agricultural products.
