A. What Guidance Does this PR Notice Provide?
The draft PR Notice announces the discontinuation of phenol resistance testing as a part of efficacy testing for antimicrobial disinfectants and sanitizers. When the PR Notice is issued in final form, the Agency will consider registering or reregistering antimicrobial disinfectant or sanitizer pesticides without supporting phenol resistance testing. All other data in support of registration or reregistration, including any required efficacy testing data, would also need to be submitted and then accepted by the Agency.
Phenol resistance testing is a standard that has traditionally been used to estimate the intrinsic resistance or sensitivity of some test bacteria to chemical disinfectants and sanitizers. For years, the Agency has been aware of the lack of standard and uniform resistance levels to phenol expressed by the test cultures used in the existing Start Printed Page 70354Official Methods of Analysis of the Association of Official Analytical Chemists (AOAC) test methods. Historically, the inability to maintain and propagate test cultures that express standard and uniform levels of phenol resistance has been a recognized scientific problem which has persisted for at least 70 years. Furthermore, the inability of many reputable and competent testing facilities to achieve consistent test results with the phenol resistance standard has prompted both concern and action by the Agency.
On September 10, 1997, after internal scientific deliberation, the Agency placed before the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) the following questions regarding phenol resistance:
What scientific direction should be taken regarding the lack of standard and uniform resistance levels to phenol of the test cultures used in the existing AOAC efficacy test methods? Should the Agency:
•Totally eliminate the phenol resistance requirement; or
•Modify the required phenol resistance patterns to provide a broader range of acceptable resistance; or
•Replace the phenol resistance requirements with some other procedures that assure hardiness and equivalence to test cultures, such as standard, quantitative inoculum level?
Briefly, the SAP responded that there is no current relevance to requiring the phenol resistance test and, therefore, the phenol coefficient method should be eliminated and new protocols should be established for defining the conditions for culturing test microorganisms with suitable resistance levels to antimicrobials.
Subdivision G of the Pesticide Assessment Guidelines, part 91-1, describes the general product performance (efficacy) standards for disinfectants and sanitizers. Subsection (b)(3)(I) of part 91-1 refers to the AOAC standard tests that may be used to satisfy the data requirements of 40 CFR 158.640. In turn, these AOAC tests include references to phenol resistance testing.
The Agency concurs with the SAP and has engaged in considerable discussion and deliberation, internally and with members of the scientific and regulated communities, on how to best proceed. Given the inapplicability of a test organism's resistance to phenol when disinfectants or sanitizers are tested for their efficacy performance, the Agency will no longer require submission of testing to demonstrate compliance with AOAC specified levels of expressed phenol resistance by test microorganisms during the efficacy evaluation of disinfectants or sanitizers. However, as an interim measure while method development research continues, the Agency generally will expect a minimum inoculum level of 104 colony forming units per carrier for all test microorganisms when the AOAC carrier based tests are used.
B. PR Notices are Guidance Documents
The draft PR Notice discussed in this notice is intended to provide guidance to EPA personnel and decision-makers and to pesticide registrants. This notice is not binding on either EPA or pesticide registrants, and EPA may depart from the guidance where circumstances warrant and without prior notice. Likewise, pesticide registrants may assert that the guidance is not appropriate or not applicable to a specific pesticide or situation.Start List of Subjects
