I can't rinse, or wash, off these yellowish bumps! They don't feel like dirt or sand! Are they larvae? I bought this Kale grown in California.
For my reference, beneath are my pics # 22, 62, 65, 68, 76, 89, 95.
I afraid, because these bumps overhead look like picture beneath like pests!
It doesn't matter what they are. Plant diseases can't infect humans; that's the stuff of science fiction. Also, eating insects is not dangerous. So you can eat the food without any actual risk.
It's good cooking practice to remove any unusual spots from the leaves, including bumps, discolorations, suspected larvae, and anything else. The reasons behind it have to do not with danger per se, but with quality. It can taste bad, many people are disgusted by it, and it's a general sign of sloppiness if you don't take care to clean the leaves from anything unusual. So cut or tear it out and only prepare the healthy green parts.
While a couple of those spots look like insect damage (by an insect that's no longer present), the rest simply look like age-related decay.
That is: that kale leaf looks like it's starting to decay due to being stored too long. I personally wouldn't use it at all, and if the rest of the kale looks like that, I'd toss it. Not because of any health threats, but simply because it's not going to taste very good.
The kale looks like it was grown in calcium deficient soil; harmless to you.
The white flies can be removed by washing your produce, rubbing lightly between your finger and thumb under running water.
