Biocidal products are authorized under Regulation (EU) No 528/2012 where it is imperative to prove that the products used are effective but do not at the same time elicit other undesirable effects on the target organisms such as increased resistance.
However, currently there are no guidelines for the assessment of such undesired side-effects. In response, the French agency ANSES issued in June 2020 methods for evaluating the appearance of a resistance/cross-resistance phenomenon, i.e. evaluating the capacity, level and maintenance of resistance that may be developed by bacteria following exposure to biocidal substances and products.
