On September 2, 2016, the U.S. Environmental Protection Agency (EPA) issued guidance to registrants on the process for making claims against emerging viral pathogens not on EPA-registered disinfectant labels (Guidance).  A draft of this guidance was issued in April 2016 and comments were sought at that time.  More information concerning the draft guidance is available in our blog item EPA Combats Emerging Pathogens Through Updating Guidance for Antimicrobial Pesticide Products.

The current Guidance document, which EPA states “provides general guidance to registrants that can be used to identify effective disinfectant products for use against emerging viral pathogens and to permit registrants to make limited claims of their product’s efficacy against such pathogens,” includes changes incorporated following EPA’s review of the three public comments received in response to that draft.  

The Guidance retains the voluntary two-stage process, but amends the first stage as indicated:

  • In the first stage, which may be performed prior to any outbreak, registrants with an eligible disinfectant product may submit a request, via label amendment or during the registration of a new product, to control a specific emerging viral pathogen to add a designated statement to the master label and additional terms to the product registration.  If the product meets the eligibility criteria suggested in this Guidance, [EPA] generally will approve the amendment.  Approval of the amendment would include additional terms and conditions of registration regarding how the designated statement may be published and communicated.

In its response to comments document, EPA responded to several comments, including:

  • Changes were made to EPA’s mandated non-label statements to remove certain language that could be considered redundant.
  • EPA is developing a coordinated process with the Centers for Disease Control and Prevention for the purpose of providing a more standardized and consistent approach to emerging viral pathogen outbreaks.  Once this process is established, the agency expects to consult with the U.S. Department of Agriculture to develop a similar approach.
  • The Guidance document allows for the addition of emerging pathogen claim language to the master label during the new product registration process if the product is eligible.  Additional language has been added to multiple locations in the Guidance document to clarify that the process is appropriate for new product registrations.
  • EPA “may consider allowing use of additional modes of claim communication under future versions of this Guidance document, however, hangtags and other promotional materials are not authorized at this time.  Because the statements authorized under this Guidance are pesticidal claims that do not meet the FIFRA registration criteria, it is essential that these off-label claims are not made outside of an emerging pathogen outbreak as described in the Guidance. Accordingly, the Guidance limits these off-label claims primarily to communications outlets that are wholly within the registrant’s control (800 numbers, social media and websites) from which the off-label claims can be immediately removed. Hangtags and other promotional materials directed towards general consumers are largely out of the registrant’s control once the products enter the chain of commerce, and may persist long after the period during which the off-label claims are authorized.”

EPA also notes that this Guidance document “provides general guidance to EPA, pesticide registrants, applicants for pesticide registrations, and the public.  This guidance is not binding on EPA or any outside parties, and EPA may depart from the guidance where circumstances warrant and without prior notice.”

In response to the increasing concerns regarding emerging viral pathogens that are not on U.S. Environmental Protection Agency (EPA)-registered disinfectant labels, EPA announced on April 7, 2016, that it was updating its Guidance regarding emerging viral pathogens.  Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is authorized to evaluate the efficacy of antimicrobial products intended to control pathogens that can be detrimental to public health.  Many believe that the process under which registrants can identify “effective disinfectant products for use against emerging pathogens,” and the process for EPA to “permit registrants to make limited claims of their product’s efficacy against such pathogens,” have not been clear and efficient.  EPA notes, for example, that “[emerging] pathogens are often unavailable commercially, and standard methods for laboratory testing may not have been developed,” such that it “can be difficult to assess the efficacy of EPA-registered disinfectants against such pathogens in a timely manner and to add these viruses to existing product registrations.”

EPA hopes that its Guidance will “expedite the process for registrants to provide useful information to the public” regarding products that may be effective against emerging viral pathogens associated with certain human or animal disease outbreaks.

EPA’s new draft Guidance document, Draft Guidance to Registrants:  Process for Making Claims Against Emerging Viral Pathogens Not on EPA-Registered Disinfectant Labels, describes “a voluntary two-stage process to enable the use of certain EPA-registered disinfectant products against these emerging viral pathogens, uses not previously identified on the product label”:

  • First Stage:  This stage may be performed prior to any outbreak. EPA summarizes the first stage as follows:  “registrants with an eligible disinfectant product may submit a request, via label amendment, to add a designated statement to the master label and additional terms to the product registration.  If the product meets the eligibility criteria suggested in this Guidance, [EPA] generally will approve the amendment.  Approval of the amendment would include additional terms and conditions of registration regarding how the designated statement may be published and communicated.”
  • Second Stage:  This stage would occur only during a human or animal disease outbreak caused by an emerging virus.  EPA summarizes this stage as follows:  “In this stage, registrants of products with the previously mentioned label amendment and terms of registration would be allowed to use the designated statement in off-label communications intended to inform the user community/public that the disinfectant product(s) may be used against the specific emerging viral pathogen.  These off-label statements can inform the public about the utility of these products against the emerging pathogen in the most expeditious manner and can be more easily removed once the outbreak has ended than statements on a label.”

Comments related to clarity of this Guidance will be accepted until May 6, 2016.  For more information, please see our memorandum EPA Announces Updated Guidance for Antimicrobial Pesticide Products Intended to Combat Emerging Pathogens.

On March 16, 2016, the European Commission (EC) issued its final report on the sustainable use of biocides.  Article 18 of the European Union’s (EU) biocidal products regulation (BPR) directs the EC to issue a report on how the BPR contributes to the sustainable use of biocidal products, and on whether there is a need to introduce additional measures, in particular for professional users, to reduce the risks posed to human health, animal health, and the environment by biocidal products.  Sustainable use for biocidal products is defined in the report as “the objective of reducing the risks and impacts of the use of biocidal products on human health, animal health and the environment and of promoting the use of integrated pest management and of alternative approaches or techniques such as non-chemical alternatives to biocidal products.”

Significantly, the EC’s report does not recommend the creation of further regulations, stating that the  “risks posed to human health, animal health and the environment by biocidal products … are already appropriately addressed by measures imposed through the conditions of approval of active substances or the authorisation of biocidal products.”  The EC also declined to extend the scope of the Framework Directive on the Sustainable Use of Pesticides (Directive 2009/128/EC) to biocidal products, stating: “due to the very diverse nature of biocidal products and the variety of applications, it does not seem appropriate to simply extend the scope of the Framework Directive on the Sustainable Use of Pesticides to biocidal products.”

Instead, the EC states that the “first and main priority” of EU Member States and industry must be “the completion of the on-going assessment of all the active substances that were already on the market when the BPD entered into force and the authorisation of biocidal products containing these active substances … with a view to promoting the sustainable use of biocidal products.”  Further, Member States also should focus on the “need to invest additional resources on enforcement activities to ensure that no product is illegally placed on their market and that biocidal products are properly labelled.” 

The EC’s report concludes by listing the following actions that it intends to pursue, and invites Member States to collaborate with the EC to do the same:

  • Focus and strengthen efforts on the review programme of existing active substances to ensure it is completed at the latest by 2024;
  • Ensure that once active substances are approved, product authorisations are granted, amended, or cancelled within 3 years;
  • Invest additional resources on enforcement activities;
  • Benefit from the legislative tools available, in particular by closely following the developments of best available techniques reference documents (BREF) that can be relevant for biocidal products used in industrial processes;
  • Encourage communication and awareness raising campaigns to inform end users, through websites, in-store leaflets or videos, quick response codes on biocidal products, etc.;
  • Encourage the development and implementation of standards (e.g., under the European Committee for Standardization), that could contribute to the sustainable use of biocidal products; and
  • Welcome research initiatives on the sustainable use of biocides and alternatives to biocidal products.

On February 10, 2016, the U.S. Environmental Protection Agency (EPA) announced it was initiating an external peer review of the updated draft protocol for testing the antimicrobial efficacy of copper-containing surface products.  The products in question are hard surface copper-containing surface products such as door handles, light switch panels, and bed rails, which are utilized for their antimicrobial characteristics.  EPA states that “the testing described in this draft protocol is designed to support registration of copper-containing surface products (such as door knobs or other items that are not intended for food contact) that bear sanitizer claims.”  Numerous changes have been made to the draft, including changes to the test microbes, culture preparation, quality control process, and product characterization.  Following completion of the review, EPA states that it will evaluate the findings and revise the draft as appropriate prior to posting the final protocol.

Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA evaluates the efficacy of antimicrobial products intended to control pathogens that can be detrimental to public health.  EPA indicates that antimicrobial efficacy testing of copper-containing surface products poses challenges because of the prolonged product life span, the likelihood that cleaning and disinfecting agents would be used on the surfaces, and the wide variation in potential product forms and use patterns.  EPA states the following regarding the protocols and how they will affect the test results:

  • This protocol is designed to address these issues by including a product characterization component that challenges the product’s physical durability and chemical stability when used as proposed;
  • The efficacy assessment component of the protocol involves evaluation of the performance of two product manufacturing lots against two pathogenic microorganisms -- Staphylococcus aureus and Pseudomonas aeruginosa; and
  • The efficacy test results, in combination with the product durability/stability component, will be used to determine the sanitizing activity of the copper-containing surface.

More information is available on EPA’s Antimicrobial Pesticide Registration website.  Information regarding other antimicrobial pesticide issues is available in our blog items EPA Posts Revised Antimicrobial Pesticides Use Site Index and EPA Releases Guidance Document:  Antimicrobial Pesticides Use Site Index.

Commentary

Products that are intended to have pesticidal efficacy over a protracted period require testing that differs materially from those pesticides that are only effective for a transient period and, thus, must be used repeatedly.  Some believe copper-containing surfaces have great promise as antimicrobial sanitizers, particularly in health care environments where limiting patient exposure to potential pathogens has become a critical institutional concern.  EPA’s enhanced test protocols are intended to address questions EPA and others have raised concerning the continued efficacy of a copper-containing surface over a prolonged life span, and the potential impact of cleaning and disinfecting agents.

On January 28, 2016, in docket EPA–HQ–OPP–2015–0302, the U.S. Environmental Protection Agency (EPA) posted its revised Antimicrobial Pesticides Use Site Index (USI).  In the USI, EPA states that it “has developed [the USI] to provide guidance about the antimicrobial pesticide use sites associated with these antimicrobial pesticide use patterns,” and it “is a guidance document to assist applicants in identifying the data that are necessary to support registration of products and to determine if labeled uses necessitate establishment of a tolerance or exemption from the requirement of a tolerance.”  EPA also posted a Response to Public Comments which stated that there have been a number of changes based on comments received, specifically from the American Chemistry Council’s Biocides Panel (ACC or Panel) and the Consumer Specialty Products Association (CSPA).  These changes include:

  • Clarifying that the USI is a guidance document and that the sites in the USI are not intended for use in labeling;
  • Simplifying the USI by organizing example use sites into broader groups;
  • Using a tabular format to provide examples of use sites organized by food use description (i.e., direct food use, indirect food use, and nonfood use) within each major use pattern category to make it easier to follow;
  • Clarifying that “food” is defined under the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. Section 321(f), and that definition applies, as appropriate, to all food use descriptions;
  • Revising the description of “nonfood use” to provide better clarity;
  • Deleting from the USI some example use sites that were ambiguous, too vague, too specific, or incorrectly categorized regarding major use pattern category or food use description; and
  • Incorporating many of ACC’s suggestions of specific use sites to include in the materials preservatives and wood preservatives general use pattern categories.

On September 8, 2015, the Environmental Protection Agency (EPA) announced that it will host a Disinfection Hierarchy Stakeholder Workshop and corresponding webinar on October 7, 2015, from 8:30 a.m. - 5:00 p.m. (EDT).  The “disinfection hierarchy” describes the descending order of susceptibility of classes of microorganisms to antimicrobial chemicals.  Demonstrated efficacy against a representative organism would support a manufacturer’s claims against more susceptible (easier to kill) organisms, potentially eliminating the need to test against, or alternatively, to submit data for each individual organism.  EPA has relied on the disinfection hierarchy concept historically.  For example, EPA relied on the disinfection hierarchy concept to take timely action to address the H1N1 virus in 2009, by allowing reliance on Influenza A data.  More recently, EPA states that it agreed that use of a registered hospital disinfectant with a label claim for use against a non-enveloped virus was appropriate for disinfection of surfaces contaminated with the ebola virus.

EPA is considering expanding its use of disinfection hierarchy concepts for the registration of public health antimicrobial pesticides.  EPA states that its goals for expanding the use of these concepts are:

  1. To provide guidance to health care officials and the public on the most effective type of registered antimicrobial products on the market to combat an emerging pathogen; and
  2. To increase the efficiency of, and lower the costs associated with, registering antimicrobial pesticides, while maintaining a high level of public health protection.

According to the announcement, the workshop will focus on the scientific merits of the hierarchy, and will provide a forum for stakeholders to discuss:

  • The current science on which disinfection hierarchy concepts are based;
  • Scientific issues that may present challenges for use of the disinfection hierarchy in registering antimicrobial pesticide products; and
  • Ideas on how to address these issues.

A panel of approximately 15 stakeholders from the public sector, academia, and industry will address a series of charge questions, followed by the opportunity for audience questions or comments.  The current list of panel members is available here.

EPA’s Office of Pesticide Programs has developed a draft white paper on disinfection hierarchy concepts that will serve as the basis for discussion during the workshop.  The draft white paper includes questions on which EPA states it is seeking input.  The agenda for the workshop is available here

More information on disinfection hierarchy is available in Bergeson & Campbell, P.C.’s (B&C®) memorandum Summary of Ninth Antimicrobial Workshop.

On September 2, 2015, the European Chemicals Agency (ECHA) issued an updated list of biocide suppliers as required under Article 95 of the Biocidal Product Regulation (BPR).  Although prior versions of the list were released previously, this list has current legal effect since Article 95 provides that, as of September 1, 2015, a biocidal product cannot be made available in European Union (EU) markets unless the active ingredient supplier or product supplier is listed for the particular product type (PT) (e.g., PT 5 (Drinking water), PT 19 (Repellents and attractants)) to which the biocide product belongs. 

The purpose of Article 95 in creating a list of persons placing active substances in the EU market is to ensure the equal treatment of persons placing active substances on the market and to avoid “free riders.”  Without the requirements in Article 95, a supplier of an active substance that has not supported the approval of that substance (either through the Review Programme of the biocide directive, or as a newcomer under the BPR) could still enter the market without compensating the entity that undertook the costs and effort to have the active substance listed. 

There will be continued updates and revisions made to the list as new suppliers seek inclusion.  In addition, ECHA states that it received 158 applications from suppliers seeking inclusion on the list, and has created a list of pending applications that ECHA is still processing.  ECHA notes:  “The list of pending Article 95(1) applications should not be confused with the list of relevant substances and suppliers (“Article 95 list”) and the presence of a company (per substance/PT/role) on the list of pending applications does not guarantee that the application will be successful and that the company will ultimately be included in the Article 95 list.”  Updates to the list also are expected for certain substances that were not within the scope of the Biocidal Products Directive (BPD) (e.g., some in situ generated active substances, substances benefiting from derogation for food and feed in Regulation 1451/2007), and for which different BPR notification and inclusion dates apply. 

Although enforcement efforts regarding the Article 95 list have not yet been tested, companies placing biocidal products in EU markets must carefully review the list to ensure that they and/or their suppliers are listed not only for the particular active ingredient and/or product at issue, but also for the product’s particular PT.

There is a one year period, until September 1, 2016, to sell existing stocks for biocide products where the suppliers are not included on the List.

On July 24, 2015, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice extending the public comment period regarding its proposed Antimicrobial Pesticides Use Site Index (USI) from July 31, 2015 to August 31, 2015.  The initial Federal Register notice announcing the availability of EPA’s guidance on the USI was issued on July 1, 2015.

By way of background, in 2014, EPA issued a final rule on Data Requirements for Antimicrobial Pesticides amending the regulations setting forth the data requirements that support an application to register a pesticide product.  The final rule contains the data requirements specifically applicable to antimicrobial pesticides that were codified in 40 C.F.R. Part 158, subpart W.  The final rule lists 12 antimicrobial use patterns in 40 C.F.R. § 158.2201.  The data requirements applicable to a pesticide product depend in part on the product’s use pattern.  The general use patterns are broad designations, and are used as columns in the antimicrobial data requirements tables to identify which data requirements might be pertinent to the particular pesticide use site.

EPA has developed the USI to assist antimicrobial pesticide applicants and registrants and to assist EPA staff to identify the use pattern that applies to a pesticide product, and thus the data requirements that must be met to register the product.  EPA states that the USI serves as a compilation of the specific use sites that are commonly listed on antimicrobial labels and links these commonly listed use sites with the twelve general use patterns.

The posting of this proposed guidance document for public comment is intended to satisfy a condition of the March 2, 2015, settlement agreement between EPA and the American Chemistry Council (ACC) that followed ACC’s July 2013 initiation of a legal challenge to the data requirements regulation in the U.S. Court of Appeals for the District of Columbia Circuit. 

In addition to extending the comments, EPA also published in the docket a Question and Answer document on the USI Webinar for questions submitted to EPA prior to the July 14, 2015, webinar.  Additional information regarding the USI is available in EPA Docket EPA-HQ-OPP-2015-0302.

On June 17, 2015, the Environmental Protection Agency (EPA) published a notice announcing the availability for comment of three draft revised 810 series test guidelines developed by the Office of Chemical Safety and Pollution Prevention (OCSPP).  These test guidelines will provide updated guidance on antimicrobial efficacy testing to the regulated community.

 

EPA states that when these guidelines were published in final in 2012, they drew criticism as confusing and inaccurate.  EPA states that the guidelines have been reformatted, corrected and updated to reflect policy and technical changes during the intervening three years.  The draft revised guidelines include expanded upfront summaries and appear more accessible with bolded titles for sections and subsections.  Recent policy and technical changes that are incorporated into the draft revised test guideline include the following:  a requirement that certain product efficacy testing must be conducted at the active ingredient’s (AI) lower certified limit (LCL) concentration; and the updated test methodology for Clostridium difficile (C. diff).  In 2013, EPA specified in separate guidance that specific efficacy testing must be conducted on products with the AI at the LCL concentration.  In 2014, EPA announced the revised C. diff test methodology.  The substance of these two guidance documents is now incorporated into the draft revised test guideline. 

 

EPA is inviting public comment on the three draft revised 810 Series test guidelines, available at the below links:

 

 

Comments must be received on or before August 17, 2015.
