Surface sampling using a single swab method.
The bacterial counts obtained from a series of one to seven swabbings of a contaminated surface showed a consistent relationship to the total count recovered. An equation was derived which can be applied to the bacterial count found by a single swabbing to obtain a quantitative estimate of the total count.
