However, the safety check of the Peruvian blueberries was incredibly strict, because there are "fruit killers" in Peru: Mediterranean tephritidae. In order to prevent these insects from entering, the Peruvian blueberries needed to be checked more strictly and thoroughly. The national head office for quarantine inspection has dispatched an official to Peru to investigate if all quarantine procedures and measures are in accordance to what has been agreed on in the trade treaty. The official is required to supervise the exports to China and to oversee and investigate thoroughly the process before export occurs. In case he discovers products that might be harmful to living organisms and should be put into quarantine, or in case he judges the cooling process before export was ineffective, then he needs to prohibit the export goods immediately or carry out corrective measures in the process. Before the Peruvian blueberries entered China, formalities of quarantine and investigation need to be handled in order to get a 'Permit of the People's Republic of China for the Quarantine of Entry for Animals and Plants'. Only then will they officially receive airplane tickets to China and a pass at the checkpoint.
Regarding the person in charge, the national quarantine office in Shanghai reminds consumers that until today the only blueberries available on the domestic fruit market come from Chile, Canada and Peru. After having entered the country through regular channels and after meeting all standards required, all these blueberries will obtain a 'Certificate of Inspection and Quarantine for Entry of Goods' and usually have the product name and the place of origin indicated on the package.
