I recommend soap and water.

Heh.

Our school is now requiring every student to bring a 235 mL container of hand sanitizer.

The FDA has just issued a warning about hand sanitizers which contain bacteria! This is from the FoxNews website:

Clarcon Biological Chemistry Laboratory Inc. of Roy, Utah, issued a voluntary recall of some skin sanitizers and skin protectants marketed under several different brand names, the FDA said in a statement.

Consumers should not use any Clarcon products and should throw them away, the FDA said.

Analyses of several samples of over-the-counter topical antimicrobial skin sanitizer and skin protectant products revealed high levels of various bacteria, including some associated with unsanitary conditions, according to the agency. Some of these bacteria can cause opportunistic infections of the skin and underlying tissues and could result in medical or surgical attention as well as permanent damage.

Can we just all go back to soap and hot water?  Seriously.
