COVID-19 Virus Surveillance for the surface of Imported Frozen Food Package

研究指出COVID-19新冠病毒（SARS-CoV-2）於室溫下能在塑膠、紙板、玻璃、金屬等材質表面存活半小時以上甚至數天，中國大陸曾在切過進口鮭魚的砧板、厄瓜多南美白蝦、巴西冷凍雞翅與豬肉、印度冷凍鯧魚與墨魚、冷凍鱈魚、雪糕、櫻桃等進口產品的包裝表面檢出新冠病毒核酸呈現陽性的結果。有鑑於食品外包裝驗出新冠病毒的新聞持續引起民眾關注，2020年10月27日中央流行疫情指揮中心指示衛生福利部食品藥物管理署（下稱食藥署）啟動進口冷凍食品包裝之COVID-19病毒監測調查之研究，首先針對冷凍肉品及水產品來自COVID-19盛行率較高的國家進行監測，2021年2月起抽驗範圍擴大為進口冷藏冷凍之肉品、水產品及水果。2021年8月為防堵Delta變異株入侵，本研究為COVID-19加強監測方案之一，並於2021年10月納入新冠病毒三大常態性監測。本研究參考世界衛生組織（WHO）及衛生福利部疾病管制署（下稱疾管署）新冠病毒檢驗方法，邊境冷凍冷藏食品包裝表面的採樣則由食藥署各區管中心協助，檢測流程整合自動化核酸萃取及One-Step qRT-PCR程序，使用SARS-CoV-2國家標準品與參考物質進行方法確認（Verification），偵測極限（LOD）可達12.5 copies病毒核酸。本研究自2020年11月6日開始至2022年8月31日結束，共計抽驗33個國家350批產品、1356件樣品，COVID-19病毒核酸檢測結果皆為陰性。

Studies indicated that the COVID-19 new coronavirus (SARS-CoV-2) can survive on the surface of plastic, cardboard, glass, metal and other materials for more than half an hour or even several days at room temperature. In the mainland China, the SARS-CoV-2 nucleic acid has been detected from the cutting board once used for imported salmon, and from the packaging surface for white leg shrimp from Ecuador, frozen chicken wings and pork from Brazil, frozen pomfret and cuttlefish from India, frozen cod, ice cream, cherries and other imported products. In view of that news of detecting the new coronavirus on the outer packaging of food kept attracting public attention, the Central Epidemic Command Center instructed the Taiwan Food and Drug Administration (TFDA) to initiate a study on SARS-CoV-2 surveillance of imported frozen food package on October 27, 2020. First, frozen meat and aquatic products were monitored from countries with high prevalence of COVID-19. From February 2021, the scope of random inspection was expanded to imported refrigerated and frozen meat, aquatic products and fruits. In August 2021, in order to prevent the invasion of the Delta mutant strain, this study was one of the enhanced surveillance programs for COVID-19, and was later incorporated into the three major routine surveillance of the SARS-CoV-2 in October 2021. The COVID-19 testing methods of the WHO and Taiwan Centers for Disease Control were employed in this study. The sampling on the surface of frozen and refrigerated products packaging at the border was assisted by TFDA Centers for Regional Administration (Northern, Central, Southern). The detection process integrates automated nucleic acid extraction and One-Step qRTPCR procedures, using SARS-CoV-2 national standards and reference materials for method verification, and the limit of detection (LOD) can reach 12.5 copies of viral nucleic acid. This study was carried from November 6, 2020 to August 31, 2022. A total of 350 batches of products and 1,356 samples from 33 countries were collected and tested. The test results of the COVID-19 virus were all negative.
