Gasoline and carbon tetrachloride have been replaced as dry cleaning fluids by perchloroethylene (perc, and also known as tetrachloroethylene), Stoddard solvent (a petroleum distillate...

OBJECTIVES Tetrachloroethylene is the dominant solvent used in dry cleaning worldwide and many workers are potentially exposed. We report here on results of 1296 measurements of tetrachloroethylene undertaken in Nordic dry cleaning shops 1947-2001. METHODS We searched documents and files in the Nordic institutes of occupational health for air measurements of tetrachloroethylene. Repeated meas...
range for these products is 4.7-4.9, whereas, pepperoni has a slightly lower pH range of 4.5-4.8 and a lower MPR of 1.6:1 as required by FSIS (FSIS, 1986). The moisture content for these products ranges from 25-39%. All of these products, because of their moisture-toprotein ratios, are considered shelf stable (FSIS, 1986; Ricke and Keeton, 1997). Semidry sausages such as summer sausage, cervela...
In 1994, an outbreak of E. coli O157:H7 infection was linked to dry, fermented, pork and beef salami. In response to this first implication of a dry fermented sausage product, the United States Department of Agriculture/Food Safety Inspection Service developed guidelines requiring sausage manufacturers to validate that their processes achieve a five-log reduction of E. coli O157:H7. Various val...
