“I have found these super small, almost invisible worms”, states this reader in Poland about the horde of tiny white organisms pictured below. “I am really worried. Please look at the picture. Is it dangerous? I could not find them in any of the food in my kitchen. They seem to be attached to this coffee machine.” She also includes a video (linked below) that shows the creatures swarming the coffee machine. Based on the location they were found, as well as their ovate shapes and white coloration, we have concluded that these are likely grain mites.
