Evaluation of a dry medium for detecting contamination on surfaces
1986
McGoldrick, K.F. | Fox, T.L. | McAllister, J.S.
A study evaluated whether a microbiological method using a new commercial dry medium flexible plate is effective in detecting microbial contamination on food contact surfaces, and compared the results to 2 accepted monitoring methods (viz., the direct contact plate (RODAC) method and the swab method). It was concluded that the new prehydrated plates detected significantly more microorganisms and had a greater repeatability than the RODAC method. No difference in repeatability was found between the new plates and Standard Agar Method pour plates for swab methods. Hence, the new plates should offer a practical alternative to other methods used for detecting microbial contamination on food contact surfaces.(wz)
