Antimicrobial packaging is an innovative active packaging, especially for meat and meat products. The present study has been carried out with the objective of prolonging the shelf life of chicken meat by using gelatin-chitosan (GC) film containing different concentrations of Cinnamon zeylanicum essential oil (CZEO) (0, 0.3, 0.6, and 0.9% v/v) at the refrigerated condition for 12 days. The obtained results indicated that the microbial count of samples wrapped with the films incorporated with the CZEO was significantly lower than control and remained below the acceptable limit of meat (7 log CFU/g). The total volatile base nitrogen (TVB-N) was 7.11 mg/100 g and after 6 days reached 30.18 mg/100 g in control, whereas it was lower than 25 mg/100 g for samples wrapped with GC films containing 0.6% and 0.9% CZEO. Compared with the control sample, the levels of peroxide value (POV) of the wrapped samples with GC films incorporated CZEO at 0.3%, 0.6 and 0.9% were decreased by 2.07, 3.23, and 3.4 meq peroxide oxygen/1000 g lipid, respectively, at the end of storage time. As a result, the integration of CZEO into GC film can extend the shelf life of the chicken meat in refrigerated conditions for at least 12 days without any unfavorable organoleptic properties

The coronavirus disease (COVID-19), caused by SARS-CoV 2, is an acute respiratory syndrome and is easily transmitted between people. The disease first started in Wuhan, Hubei Province, China, and then quickly spread to more than 200 countries. In March 2020, the World Health Organization announced the outbreak of the disease as a global epidemic, and it is a great challenge that has affected all nations. Initially, governments in various countries, to prevent the spread of this disease, took stubborn measures, including complete lockdown. It seems that little attention has been paid to food hygiene and its association with the coronavirus disease (COVID-19) pandemic. Transmission risk of SARS-CoV-2 is possible through food department staff to food products and food contact surfaces. Recently, cases of survival of SARS-CoV 2 through various surfaces have been reported. The possibility of transmission and survival of SARS-CoV2 via food is discussed based on previous information for other respiratory viruses such as MERS-CoV and SARS-CoV. Nevertheless, studies are needed to survey the possibility of its transmission and survival via food. In the face of challenges such as the current epidemic, the flexibility of a system such as the food industry is critical to protecting producers' and consumers' health to reduce the risk of outbreaks by implementing new approaches.
