Do you want non-toxic disinfectant against drug-resistant tuberculosis with your chips?
The good people at Global Biodefense (here) picked up the story that vinegar, or more correctly acetic acid, is an effective decontaminant for TB and other mycobacteria.
A study at the Venezuelan Institute of Scientific Investigation, University of Montpellier 2 and the Albert Einstein College of Medicine in New York showed that a 6% solution of acetic acid, only slightly stronger than you can get at the Mall, could have a major effect on killing TB and other mycobacteria. Whole this only builds on work done on acetic acid at the start of the last century this discovery is likely to make a huge difference to poorer countries that have a difficult time affording stronger bleaches.
Since modern TB is extremely drug resistant this ability to deal with it before it takes hold in the body is likely to drastically improve people's lives in the poorest countries.
