Use of copper cast alloys to control Escherichia coli O157 cross-contamination during food processing

Article Abstract:

Study is conducted to evaluate seven cast copper alloys (61 to 95% Cu) for their ability to reduce their viability of E.coli O157, mixed with or without ground beef juice, and to compare these results to those for stainless steel. The results clearly demonstrate the antimicrobial properties of cast copper alloys with regard to E. coli O157, and consequently these alloys have the potential to aid in food safety.

Inactivation of influenza A virus on copper versus stainless steel surfaces

Article Abstract:

Influenza A virus particles are inoculated onto copper or stainless steel and the infectivity of survivors are determined by using a defined monolayer with fluorescence microscopy analysis. The analysis has shown that copper surfaces might contribute to the number of control barriers able to reduce the transmission of the virus, particularly in the facilities like schools and health care units.

Shear stress, temperature, and inoculation concentration influence the adhesion of water-stressed Helicobacter pylori to stainless steel 304 and polyprophylene

Article Abstract:

The study represents the first report on the effect of different conditions on the adhesion of Helicobacter pylori to a pipe material. The adhesion of H. pylori suspended in distilled water to stainless steel (SS304) coupons placed on tissue culture plates subjected to different environmental conditions was monitored.
