The FDA is not warning about "denatured alcohol."
They are warning about methanol, i.e. methyl alcohol, often known as "wood alcohol."
Methanol is toxic and can be absorbed through the skin. It may cause blindness, seizures or death when ingested.

The hand sanitizers in question, largely from Mexico, have been found to contain methanol (not denatured alcohol) despite having ethanol listed on the label. These product are potentially toxic, especially to children.

Denatured alcohol is ethanol to which additional chemicals have been added to discourage people from drinking it. The chemicals typically cause a foul odor, foul taste or nausea. However the added chemical could be methanol, in which case it certainly could be "incrementally unhealthy". Note that this is not a new "decision."

Jerry is right to advocate for washing with soap and water. Soap and water kill far more "germs" compared to hand sanitizers, which should always be a second choice for use when soap and water are not available.

About a month or so ago, I saw this little lonely Orchid discarded in the pet food aisle at the local ghetto Kroger store. I just have sucker weakness for this kind of stuff. Wait until I post my kitty cat pictures and you will see. It looked pretty bad and was marked down to 3 bucks. I took this baby home. This was just a month ago.
Look at her now, and those who know, Orchids grow very slow.
I wish I had shot some pictures of her when I got her. One flower had dropped dead already.

The story goes with the pictures and the pictures go with the story.

Nikon D200 with Nikon AF 28-80 Lens. Camera set to A, auto.
Used Light Room Classic and LR CC to auto adjust and just slightly tweak exposure and contrast.

Now, for all you HOGGERS who have house and outdoor plants and flowers, the magic sauce I have found that works miracles for my Orchids and this little baby I am posting is living proof of this natural stuff I have been using and the plants LOVE IT. I add SuperThrive to the watering bowl. I have been using this new stuff which is a real miracle, it is called Worm Tea. I get it from Florida and and OH WOW ! Do my babies love it? Check it out.

I found this unknow little flying beetle laying in the bottom of the dog's outdoor water bowl when I freshened it this morning. I picked it out with tweezers and brought it in and staged it for a focus stacking session. Because it was in the water for quite some time it was very supple so I was able to move its legs and antenna where most other specimens are far too stiff to get into a good position.

It is yet another specimen that found its way to me. I also rescued a female jumping spider that walked in the door while it was open and hopefully she will find a convenient home on our porch where I will be able to see her from time to time.
