title: Semi-log model for interpreting the results of swabbing surfaces naturally contaminated.
abstract: Two mathematical models for depicting microbial depletions during six consecutive swabbings of refrigerated tank wall and teat skin were tested. Although a second degree polynomial equation gave a better adjustment of the data, a first degree equation was preferred to calculate the total numbers of micro-organisms possibly retrieved from surfaces by swabbing. This model was used for estimating the level of milk contamination by teat skin.
