Coronavirus can remain on plastics for up to three days
The U.S. National Institutes of Health found that the coronavirus can remain infectious on plastic surfaces for up to three days. This has led to a reversal of plastic bag bans in several U.S. states and cities, including Massachusetts, San Francisco, Colorado, Illinois, Maryland, and New Hampshire. These jurisdictions have either stopped enforcing their plastic bag bans or banned reusable bags outright.
The concern is that reusable bags could be contaminated with the coronavirus and pose a risk to grocery store staff and other customers. However, the risk of contracting the coronavirus from contaminated surfaces remains uncertain, according to public health experts.
To reduce the risk of contamination, it is recommended to practice good hand hygiene and disinfect communal surfaces after unpacking groceries. Reusable bags should be washed regularly, and single-use plastic bags should be discarded immediately after use.
While the concern about contamination on plastic surfaces is valid, it is important to note that the coronavirus is primarily spread through respiratory droplets in the air. Thoroughly cleaning all surfaces and practicing good hand hygiene are still recommended to minimize the risk of infection.

Bans on single-use plastic bags have been reversed
Bans on single-use plastic bags, which have been implemented in various countries and states to reduce plastic pollution, have been reversed in several locations due to the COVID-19 pandemic. The primary concern is the risk of virus transmission from reusable bags.
In the United States, states like Oregon, Massachusetts, and Illinois have temporarily suspended their bans on plastic bags. Before the pandemic, many cities and states across the U.S. were actively banning straws, limiting takeout containers, and mandating the use of reusable bags or charging fees for single-use plastic bags. However, with the outbreak of COVID-19, there is a heightened concern about the virus clinging to reusable items, leading to the reversal of these bans.
The plastic bag ban in Oregon, enacted in January 2020, was one of the first to be suspended during the pandemic. Cities like Bellingham, Washington, and Albuquerque, New Mexico, have also announced a hiatus on plastic bag bans. These decisions are made to prevent the potential spread of the virus through contaminated bags.
The COVID-19 pandemic has highlighted the complexities of balancing public health and environmental concerns. While single-use plastic bags contribute significantly to plastic pollution, the fear of virus transmission has temporarily shifted priorities. It is important to note that the plastic industry's resistance to bag bans and the challenge of enforcing such bans have also played a role in these reversals.
Beyond the United States, other countries have also faced challenges in maintaining single-use plastic bag bans. For example, in 2023, Athens, Ohio, overturned its bag ban when a judge called it "unconstitutional" due to a conflict with state law. Additionally, countries like Kenya, the Bahamas, and cities in Indonesia, such as Bali, Jakarta, and Surabaya, have implemented bans on single-use plastic bags, but it is unclear how the pandemic has impacted these regulations.

Cloth bags can be washed with detergent
The COVID-19 pandemic has caused a shift in the use of plastic bags, with some states in the US temporarily suspending bans on plastic bags due to concerns about the virus spreading via reusable bags. A study by the U.S. National Institutes of Health found that the novel coronavirus can survive on plastics for up to three days, highlighting the potential risk of contamination from plastic surfaces.
While the focus has been on plastic bag usage, it is important to address the safety concerns regarding cloth bags. Cloth bags, unlike plastic bags, can be washed with detergent to reduce the risk of virus transmission. Washing cloth bags with detergent is a recommended practice to ensure the sanitization of these reusable items. Here are some key considerations and guidelines for washing cloth bags:
- Washing Machine Settings: When washing cloth bags in a washing machine, it is advisable to use the delicate cycle or a slower spin cycle. This gentler approach helps protect the bag and any delicate items inside from potential damage caused by high-speed agitation.
- Detergent Selection: Choose a suitable detergent, preferably one designed for delicate fabrics. Fragrance-free detergents are ideal for individuals with sensitive skin. Ensure the detergent effectively removes stains, dirt, and any virus particles.
- Temperature and Drying: Consider using warm or hot water during the wash cycle, as higher temperatures can aid in sanitization. Regarding drying, cloth bags can be air-dried or machine-dried according to the care instructions.
- Bag Maintenance: Inspect your cloth bags regularly for any wear and tear. If the bag has a lining, ensure it is intact and clean. Replace cloth bags that show signs of extensive damage or wear, as they may be less effective at preventing contamination.
- Washing Frequency: Wash your cloth bags regularly, especially if they have been used in public places or high-risk environments. The frequency of washing depends on usage, but a good guideline is to wash them after each significant shopping trip or exposure.
By following these guidelines and maintaining proper hygiene practices, individuals can effectively use and sanitize their cloth bags, reducing the potential risk of coronavirus transmission associated with reusable bags. Cloth bags, when washed with detergent, offer a more sustainable and environmentally friendly alternative to disposable plastic bags.

Plastic bags can be disinfected with household disinfectants
The COVID-19 virus can remain on plastic surfaces for up to three days, according to a study by the U.S. National Institutes of Health. This has raised concerns about the virus clinging to reusable bags, leading some US states to suspend bans on single-use plastic bags.
However, it is important to note that the risk of infection from a plastic bag is relatively low compared to other high-contact surfaces. The primary mode of transmission for COVID-19 is aerosolized droplets, which are unlikely to be contained by a plastic bag.
Nonetheless, it is crucial to disinfect plastic bags and other plastic items to prevent the spread of the virus. Here are some effective methods for disinfecting plastic bags and other plastic items using household disinfectants:
- Wash the plastic bag with antibacterial dish soap and hot water. While this may not guarantee complete sterilization, it will immediately kill surface bacteria.
- For increased effectiveness, combine washing with a non-diluted alcohol rinse. Both rubbing alcohol and grain alcohol are effective at killing bacteria on plastic surfaces.
- Soak the plastic bag in a bleach-water solution of about 5 to 10 percent bleach. Bleach is a powerful disinfectant and will quickly disinfect the surface.
- Heat treatment is another option. Wet the plastic bag and place it in the microwave on high power for approximately two minutes. Alternatively, use a dishwasher on a hot rinse cycle. However, be cautious as excessive heat can melt some types of plastic.
- Polypropylene plastics are stronger and can withstand higher temperatures, so a microwave or dishwasher is more suitable for these items.
- UV light is another safe and effective method for sterilizing plastic. Place the plastic item under a UV lamp for a non-heated disinfection method.
By following these simple steps, you can effectively disinfect plastic bags and other plastic items, reducing the risk of COVID-19 transmission and helping to keep yourself and others safe.
