Prohibition of various powders
Now, what’s wrong with talcum powder, you ask? Nothing really. The problem is that the powers-that-be cannot tell just from glancing at it whether it really is just bath powder or if it’s actually something dangerous or toxic.
Because of this, TSA officers carefully inspect any powder in quantities of more than 350 milliliters. (To those not familiar with the metric system, that’s roughly the size of a regular soda can. If the TSA cannot be certain the powder is harmless, you will be asked to throw it in the trash. So when you pack don’t pack powders in your carry-on bag. If you insist on not taking that advice, take it out of your carry-on and put it in a bin prior to inspection.
‘Dense’ foods will be thoroughly inspected
Passengers could now be asked to remove food from their carry-ons. This is especially able to happen if the food so “dense” that it somehow impedes the X-ray equipment’s ability to scan the other things with which it is packed. What does the TSA define as “dense?” Some examples they cite are baby food, baby formula, breast milk, and similar canned foods. Travelers are advised to remove these items and put them into bins ahead of time to facilitate easier screening.
