A product that has GRAS status, acidified calcium sulphate is an organic acid and calcium sulfate combination that kills Listeria on the surface of products such as lunchmeats and certain cheeses, and keeps the bacteria from growing back. Listeria is responsible for causing foodborne listeriosis, which causes flu-like symptoms, meningitis, spontaneous abortions and prenatal septicemia. About 20% of the illnesses are fatal. Until now, lactic acid and sodium lactate have offered some microbiological protection, but they cannot completely stop the organisms from reappearing. However, a study carried out at Texas A&M University and funded by the American Meat Institute Foundation demonstrates the acidified calcium sulphate appears to be able to do so.
