How was the new study conducted?
Samples of manufactured bathtubs that contain both the untreated and treated acrylic sheets were purchased from retail establishments and cut into samples. Each sample was exposed to strains of bacteria, including Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and Streptococcus faecalis (S. faecalis). The acrylic samples sat for periods of 0, 4 and 24 hours. The bacteria were then removed from the acrylic surfaces and measured and counted according to standard protocol.
