“…Moreover, several major outbreaks in meat products manufacturing plants in the United States, the United Kingdom, and Germany indicate that the high humidity and cold conditions of these places may contribute to the spread of the virus 12 . Thus, the packaging materials used in food production processes, as well as the food itself, may be contaminated by viruses shed by infected persons and become sources of outbreaks 13,14 …”

“…12 Thus, the packaging materials used in food production processes, as well as the food itself, may be contaminated by viruses shed by infected persons and become sources of outbreaks. 13,14 Recently, the stability of SARS-CoV-2 on various surfaces, such as plastic, copper, stainless steel, human skin, and currency, has been reported, providing useful information for epidemic control. [15][16][17] However, there have been only a limited number of investigations into the viability of SARS-CoV-2 on food surfaces, such as meat products and fruits.…”

SARS-CoV-2 is still spreading globally. Studies have reported the stability of SARS-CoV-2 in aerosols and on surfaces under different conditions. However, studies on the stability of SARS-CoV-2 and viral nucleic acids on common food and packaging material surfaces are insufficient. The study evaluated the stability of SARS-CoV-2 using TCID 50 assays and the persistence of SARS-CoV-2 nucleic acids using droplet digital polymerase chain reaction on various food and packaging material surfaces. Viral nucleic acids were stable on food and material surfaces under different conditions. The viability of SARS-CoV-2 varied among different surfaces. SARS-CoV-2 was inactivated on most food and packaging material surfaces within 1 day at room temperature but was more stable at lower temperatures. Viruses survived for at least 1 week on pork and plastic at 4°C, while no viable viruses were detected on hairtail, orange, or carton after 3 days. There were viable viruses and a slight titer decrease after 8 weeks on pork and plastic, but titers decreased rapidly on hairtail and carton at -20°C. These results highlight the need for targeted preventive and disinfection measures based on different types of foods, packaging materials, and environmental conditions, particularly in the cold-chain food trade, to combat the ongoing pandemic.

“…Epidemiological investigation and the whole genome sequence of SARS-CoV-2 were the main methods for tracing the origin of COVID-19 in each outbreak. 34 However, there were still some limitations in our study. Five outbreaks might transmit to humans from the contaminated items, including two outbreaks from the cold-chain transmission and three outbreaks from items contaminated to humans.…”

Different variants of severe acute respiratory syndrome coronavirus 2 have been discovered globally. At present, the Omicron variant has been extensively circulated worldwide. There have been several outbreaks of the Omicron variant in China. Here, we investigated the epidemiologic, genetic characteristics, and origin-tracing data of the outbreaks of COVID-19 in Beijing from January to September 2022. During this time, 19 outbreaks occurred in Beijing, with the infected cases ranging from 2 to 2230. Two concern variants were detected, with eight genotypes. Based on origin tracing analysis, two outbreaks were from the cold-chain transmission and three from items contaminated by humans. Imported cases have caused other outbreaks. Our study provided a detailed analysis of Beijing's outbreaks and valuable information to control the outbreak's spread.
