From the first notification reporting to the WHO a cluster of coronavirus in Wuhan City (China), over 114 million cases of SARS-CoV-2 have been confirmed, with more than 2,530,000 deaths, and over 400,000 new cases and 10,000 deaths daily. Numerous viruses are susceptible to contaminate crops during growth, harvesting, handling, marketing and minimally processing, and these steps share one common factor which is human. Different studies showed that viruses might persist on different crops for periods of 2 to 14 days under different conditions such as refrigeration, household and freezing. Little is known on SARS-CoV-2, but preliminary studies showed that this virus might survive 24 hr on cardboard and 72 hr on plastic, materials used in fruits and vegetables packaging. Based on preliminary data, there is no evidence of food or food packaging being associated with transmission of SARS-CoV-2. Certainly, to date there is no scientific evidence that SARS-CoV-2 might be transmitted by a contact with, or the ingestion of contaminated fresh or minimally processed fruits and vegetables. However, this risk even though being considered improbable, it cannot be "" discarded or ignored, particularly where the virus is spreading in the word. Some agencies indicated that in case some commodities and handlers are contaminated among the multiple people involved from the farm to the table, a cross-contamination may occur, and the risk of the contamination of food, food contact materials, and packaging from infected but asymptomatic workers should not be discarded even though considered "."
从向世卫组织报告中国武汉市出现冠状病毒聚集性病例的第一份通报起,全球已确诊超过1.14亿例新冠病毒病例,死亡人数超过253万,且每日新增病例超过40万例、死亡超过1万例。许多病毒在作物生长、收获、处理、销售和最低限度加工过程中都容易污染作物,而这些环节都有一个共同因素,即人。不同研究表明,在冷藏、居家及冷冻等不同条件下,病毒可能在不同作物上存活2至14天。关于新冠病毒的情况了解较少,但初步研究表明,这种病毒在硬纸板上可能存活24小时,在塑料上可能存活72小时,而塑料是水果和蔬菜包装中使用的材料。根据初步数据,没有证据表明食品或食品包装与新冠病毒传播有关。当然,迄今为止,没有科学证据表明新冠病毒可能通过接触或摄入受污染的新鲜或最低限度加工的水果和蔬菜传播。然而,尽管这种风险被认为不太可能,但不能“排除或忽视”,特别是在病毒正在全球传播的情况下。一些机构指出,如果从农场到餐桌涉及的众多人员中有一些商品和处理者受到污染,可能会发生交叉污染,即使认为“可能性不大”,受感染但无症状的工人污染食品、食品接触材料和包装的风险也不应被排除。
