Three hundred and sixty two liquid and semiliquid (emulsion in the form of lotions and creams) pharmaceutical products used at homes in Amman were examined microbiologically. Thirty six percent of these samples were contaminated. Gram staining of representative organisms isolated from the contaminated samples showed that 26% contained Gram negative rods; 38% contained Gram positive cocci and 35% Gram positive rods. The most common species of Gram negative rods were Escherichia coli, Pseudomonas spp., Enterobacter spp. and Klebsiella spp.
