Since the outbreak of Covid-19, many people have been concerned about the safety of their food and groceries. One common question is whether the virus can survive in the refrigerator or freezer. In this article, we will explore the latest scientific research to answer this pressing question.
According to experts, Covid-19 is primarily transmitted through respiratory droplets when an infected person coughs or sneezes. However, there is growing evidence that the virus can also be spread by touching contaminated surfaces. This has raised concerns about whether the refrigerator or freezer, common household appliances, can serve as potential sources for transmission.
Recent studies have shown that the coronavirus can survive on different surfaces for various periods of time. While it is known to survive on plastic and stainless steel for up to 72 hours, the virus has a shorter lifespan on porous surfaces and materials like cardboard or fabric. This raises the question of whether Covid-19 can survive and remain infectious on food products stored in the refrigerator or freezer.
The good news is that there is currently no evidence to suggest that Covid-19 can survive and remain infectious on food or food packaging surfaces for an extended period of time, including in the refrigerator or freezer. According to the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), the risk of contracting coronavirus from contaminated food or food packaging is considered very low. This is because the virus primarily requires a living host to replicate and survive.
Impact of Cold Temperatures
As the Covid-19 pandemic continues to spread, it is important to understand the impact of cold temperatures on the survival of the virus. Cold temperatures can have a significant effect on the virus, offering both advantages and disadvantages.
Advantages:
- Cold temperatures can help slow down the spread of the virus. When the virus is exposed to cold temperatures, it tends to survive for a shorter period of time.
- In a refrigerator or freezer, the cold temperatures can potentially inhibit the growth and replication of the virus.
- If an infected surface or object is stored in a cold environment, the virus may become less infectious over time.
Disadvantages:
- Cold temperatures do not completely eliminate the risk of transmission. The virus can still survive for a certain amount of time in refrigerators and freezers.
- Although the virus may survive for a shorter period of time in cold temperatures, it can still be viable for hours or even days.
- If contaminated items are not properly handled or cleaned, the virus can still pose a risk of transmission even after being stored in cold temperatures.
Precautions:
While the impact of cold temperatures on the survival of Covid-19 can be advantageous in some ways, it is important to take necessary precautions to prevent transmission:

- Wash hands frequently and properly with soap and water for at least 20 seconds.
- Use hand sanitizers with at least 60% alcohol content.
- Practice good respiratory hygiene by covering your mouth and nose with a tissue or your elbow when coughing or sneezing.
- Follow local and international health guidelines to prevent the spread of the virus.
Understanding the impact of cold temperatures on the survival of Covid-19 is crucial in implementing effective preventive measures. By taking appropriate precautions, individuals can reduce the risk of transmission and protect themselves and others from the virus.
Transmission Methods
Coronavirus disease (Covid-19) is primarily transmitted through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. These droplets can enter the body through the nose, mouth, or eyes of a person nearby. However, it is important to note that Covid-19 can also be spread through other methods:
1. Direct Contact
Covid-19 can be transmitted by touching surfaces or objects that have the virus on them and then touching the face, particularly the eyes, nose, or mouth. This makes it crucial to practice proper hand hygiene by washing hands frequently with soap and water for at least 20 seconds or using hand sanitizers with at least 60% alcohol content.
2. Indirect Contact
Indirect contact transmission occurs when a person comes into contact with respiratory droplets that have landed on surfaces or objects. It is possible for the virus to survive on certain surfaces for varying lengths of time, which is why it is necessary to regularly clean and disinfect frequently-touched objects and surfaces.
While the Covid-19 virus can survive for extended periods on different surfaces, there is no evidence to suggest that the virus can survive in the refrigerator or freezer. The cold temperatures within these appliances may actually inhibit the virus’s ability to survive and remain infectious. However, it is still important to maintain good hygiene practices, such as cleaning and sanitizing these appliances regularly.
Although the primary mode of transmission is through respiratory droplets, it is essential to remain vigilant and follow recommended guidelines to minimize the risk of Covid-19 transmission. This includes wearing face masks, practicing social distancing, avoiding crowded places, and regularly sanitizing hands and surfaces.
Survival on Surfaces
Coronaviruses, including COVID-19, can survive on different surfaces for varying periods of time. Understanding how long the virus can survive on surfaces is crucial in preventing its transmission. Here are some important facts about COVID-19 survival on surfaces:
- Metal and plastic surfaces: COVID-19 can survive on these surfaces for up to several days, depending on the specific material. Stainless steel and plastic surfaces, such as those commonly found in refrigerators and freezers, can harbor the virus for a significant amount of time.
- Glass surfaces: The virus can also survive on glass surfaces, like the ones found in refrigerator doors, for a similar duration as metal and plastic surfaces.
- Temperature and humidity: The survival of COVID-19 on surfaces is influenced by environmental factors like temperature and humidity. Lower temperatures and higher humidity levels tend to prolong its survival.
- Freezing temperatures: While it is known that certain viruses can survive in freezing temperatures, there is currently limited scientific data on COVID-19’s survival in the freezer. However, it is advisable to regularly clean and disinfect freezer surfaces to reduce the risk of transmission.
- Cleaning and disinfection: Regular cleaning and disinfection of commonly touched surfaces, including refrigerator and freezer handles, can help reduce the risk of COVID-19 transmission. Use approved cleaning agents and follow recommended guidelines for effective disinfection.
- Hand hygiene: Practicing good hand hygiene, including washing hands frequently with soap and water for at least 20 seconds or using hand sanitizers with at least 60% alcohol, is essential in preventing the spread of COVID-19.
It is important to note that while COVID-19 can survive on surfaces, the primary mode of transmission is through respiratory droplets from an infected person. Therefore, practicing good respiratory hygiene, maintaining social distancing, and following public health guidelines are of utmost importance in preventing the spread of the virus.
Potential Risks
While it is unlikely for Covid-19 to survive in the refrigerator or freezer, there are still potential risks that need to be considered and precautions that should be taken.
