If used properly, moderate or high heat can be used to “kill” coronavirus, inactivating the virus so that it is no longer infectious. However, in many cases this may be more time-consuming than other methods such as chemical disinfection (with disinfecting wipes or sprays) and there is often no need to disinfect packaging at all if you can just remove the packaging, dispose of it (preferably by recycling), and then disinfect your hands by washing with soap and warm water or using another disinfection method. Furthermore, the FDA has stated that “…there is currently no evidence of human or animal food or food packaging being associated with transmission of the coronavirus that causes COVID-19.” Although the agency notes “…if you wish, you can wipe down product packaging and allow it to air dry, as an extra precaution.”
