Antimicrobial Overkill

Disinfectant overkill with spray bottle and plastic glove

Antimicrobial cleaners and treatments—disinfectants—kill bacteria, viruses, and fungi, but they also have potential harmful health and environmental effects. They don’t distinguish between good bacteria and bad bacteria. But, a lot of people continue to use antibacterial household products that promise hygiene and safety. Everyone wants to be safe, don’t they?

Use of disinfectants such as nano silver in everyday situations is overkill. Even in more extreme situations, there is a lot of debate about whether the antimicrobial benefits outweigh the potential risks.

Nano silver is not new but it has been used in more household products in the past decade, so concerns have seen more publicity. It can be embedded in plastics (pacifiers and baby bottles), coated on textiles (anti-bacterial socks or baby products), and even added to soaps labelled “all natural” (though it is banned in Canadian organics).

The U.S. EPA is considering an application to register nano silver as a pesticide, which the Natural Resources Defense Council vigorously opposes as “illegal, irresponsible, and potentially dangerous to the public.” Unfortunately, the application to use nano silver as a pesticide is just a clever way to keep it on the market until a final decision is made. Nanomaterials are regulated by Environment Canada as pollution and waste.

Though marketed by some as an alternative cure-all, even most alternative medicine practitioners warn against claims made for unregulated medicinal silver use.

Nano silver particles are super small, 1-100 nanometers, which is a lot closer to the size of an atom than to the width of a hair. Their size means they can penetrate and accumulate in tissue. Particles coating fabrics don’t necessarily stay on fabrics. Since the particles are too small to be filtered out during the wastewater treatment process after they have been freed from antibacterial soap or socks or diaper bags or towels or even washers, the particles stay in the water after they wash down the drain. These antibacterial particles could even kill microbes used in wastewater treatment. Once these nano particles are released into the waterways, aquatic life will encounter them. A study of the effect of nano silver on zebrafish “found that some died and others were left with dramatic mutations.” Studies find problems in plant life with nano particles in soil.

Given that nano silver can have an effect on the immune system, cause neurological problemsresult in kidney damage, and boost greenhouse emissions, it looks like a threat to public health.

Too many disinfectants do the job so well that they harm more than the bacteria they are intended to kill. It’s like using a sledgehammer for a push pin. For cautions and alternatives to heavy-handed disinfectants like chlorine bleach, Triclosan, and nano-silver, read Disinfectant Overkill from Women’s Voices for the Earth.

  1. You say that the nano-silver is in socks. Is this also the same “silver” that is used in anti-bacterial microfiber cloths? Thought they would be good replacement for many of the chemical cleaners used in the house…..maybe not!??

    • Probably not. Always check with the manufacturers to figure out if nanosilver is the way they are creating their anti-bacterial fabrics. Have you tried white vinegar for household cleaning? If you want anti-bacterial cleaning, you could add a few drops of tea tree or another anti-bacterial essential oil to warm water for wiping down surfaces.

  2. I love reading your blog posts and find them beneficial, however although you mention the possible negative effects of nano silver, your store continues to sell Jujube accessories which contain AgION and Teflon. What are your thoughts on these materials and their effects on our health and the environment?

    • Thanks for your comment, Maureen! We’re always considering new products. When alternatives present themselves that are practical for mom, while also being safer for our health and the environment, we’re one of the first stores to explore them. There are some very practical reasons why Ju-Ju-Be chooses this technology, but there’s almost always room to make better choices. Despite the choice of antibacterial treatment, we still feel Ju-Ju-Be makes one of the most practical, durable, long-lasting diaper bags on the market, and this in itself has advantages. I would definitely encourage you to email any concerns to Ju-Ju-Be directly, and perhaps we’ll see changes in the future. In the meantime, you can read on their website why they have made the choice they have.
