The U.S. Transportation Security Administration (TSA) announced a list of foodstuffs that terrorists are tempted to use as tools. The TSA also identified a food that’s at low risk of being misused. The official word:
Travelers should know that while pies are permitted through the security checkpoint, here is a list of liquids, gels and aerosol items that you should put in your checked bag, ship ahead, or leave at home.
Comestibles that are too tempting to terrorists include: gravy; jams; jellies; peanut butter; maple syrup; salsa; sauces; and many others. See the full list for details. NOTE: The TSA has not described the test protocols used to obtain these results.
