On September 17, 2019, the European Food Safety Authority (EFSA) opened a consultation period on two pilot assessments of the risks posed to humans by residues of multiple pesticides in food. EFSA is seeking comments from interested parties on the assessments. The first assessment considers the chronic effects of multiple pesticides on the thyroid system. The second looks at acute effects on the nervous system.
EFSA produced the assessments in collaboration with the National Institute for Public Health and the Environment for the Netherlands (RIVM) using monitoring data from 2014, 2015, and 2016. In approving pesticides for use in the European Union (EU), EFSA establishes a maximum level of pesticide residue (MRL) allowed in food or animal feed. The MRL considers the cumulative effects of pesticides. Pesticides may only be placed on the EU market if they have no harmful effects on humans, including cumulative effects. In the two pilot assessments, EFSA classified pesticides into “cumulative assessment groups” (CAG) based upon whether they produce similar toxic effects in a specific organ or system. EFSA states that “[t]he overall draft conclusion for both assessments is that consumer risk from dietary cumulative exposure is below the threshold that triggers regulatory action for all the population groups covered.”
In 2020, EFSA will prepare the assessments in final, which will serve to “inform risk managers in the European Commission and Member States who regulate the safe use of pesticides in the EU.”
EFSA will present the assessments at a special stakeholder event in Brussels, Belgium, on October 22, 2019. The meeting is intended to allow stakeholders with expertise and interest in the area to discuss the technical issues relating to the draft assessments. Registration for the meeting closes on October 11, 2019.
All comments must be submitted by November 15, 2019. Comments on the “Cumulative dietary risk characterisation of pesticides that have chronic effects on the thyroid” may be submitted at https://ec.europa.eu/eusurvey/runner/PC_CRA_Thyroid_Sept-2019. Comments on the “Cumulative dietary risk characterisation of pesticides that have acute effects on the nervous system” may be submitted at https://ec.europa.eu/eusurvey/runner/PC_CRA_Nerv_Syst_Sept-2019.
The two draft assessments are available on EFSA’s website.

On May 31, 2017, the U.S. Environmental Protection Agency (EPA) announced the release of its Food Contact Sanitizing Solutions Model (FCSSM), a pesticide risk assessment model that has been developed to “estimate indirect dietary exposure to components of sanitizing solutions used in commercial settings.” EPA states that “the model offers guidance for estimating exposure where there may be inadvertent transfer of residue to edible items prepared or transported on surfaces treated with these pesticides.” The model consists of spreadsheets that automatically calculate dietary exposure and risk estimates based on data entered by the user. The model estimates exposures to antimicrobial active ingredients listed under 40 C.F.R. § 180.940(b) and 40 C.F.R. § 180.940(c), where 940(b) includes uses in dairy processing equipment and food processing equipment and utensils, while 940(c) excludes dairy processing equipment. FCSSM does not apply to active ingredients listed under 40 C.F.R. § 180.940(a), which are used on food contact surfaces in public eating places as well as dairy and food processing equipment. For this case, EPA’s established methodology remains in place. Compared to the simple calculation method used previously for these use scenarios, the major new feature of the FCSSM is the separate calculations of both acute and chronic dietary exposures for the general U.S. population and eight subpopulations. EPA also released a user guide that provides background information on the model and familiarizes users with the inputs required to run the model.
More information about the FCSSM as well as other models used for pesticide risk assessments is available on EPA’s website.

On June 3, 2015, the General Court of the European Court of Justice issued a ruling in Luxembourg Pamol (Cyprus) Ltd. and Luxembourg Industries Ltd. (Luxembourg) vs. European Commission regarding the publication of information by the European Food Safety Authority (EFSA) in its peer reviewed draft assessment report of potassium phosphonate that Luxembourg claimed as confidential.
The case was brought by Luxembourg after EFSA rejected Luxembourg’s claim that certain information be treated as confidential, and not included in the EFSA’s peer reviewed draft assessment report on potassium phosphonate. The European Commission agreed with EFSA. EFSA stated that under the Plant Protection Product Regulation No. 1107/2009 (and Article 14 of its predecessor Directive 91/414) and European Union (EU) Regulation No. 199/2011 setting forth procedures for reviewing certain active substances including EFSA’s peer review of draft assessment reports, confidential status cannot be extended to: information on the composition of the substance at issue; the analysis method for that substance; the analysis methods for residues; the scientific information on the basis for the evaluation and risk assessments performed; and information already in the public domain. After EFSA refused the confidentiality request, Luxembourg sought reconsideration by the European Commission, who found that the sanitization principles applied by EFSA “reflect a common understanding of EFSA and the Commission of the provisions of Article 14 of Directive 91/414/EEC.”
In its decision, the Court dismissed the lawsuit because Luxembourg brought the case against the European Commission when the appropriate party was EFSA. The Court agreed with the Commission that the decision at issue was an act of and attributable to EFSA, stating that while the Commission “indicated to EFSA the legislation and principles applicable to the requests for confidentiality at issue, the fact remains that the Commission did not apply that legislation and those principles in order to determine those claims itself.” The Court stated that Article 7(2) of Regulation No. 188/2011 grants EFSA to make confidentiality determinations “in its own right” and that Articles 12(1) and 60 of Regulation No. 1107/2009 show that EFSA is “competent to adopt a decision on a request for confidentiality.”
While this decision does not provide certainty or guidance to industry regarding the type of information that can be claimed, and accepted, as confidential, it does add to a growing pool of cases addressing complex issues regarding the confidential treatment of information related to agrochemicals. This includes, but is not limited to, the ongoing case following the European Court of Justice’s October 8, 2013, ruling that the European Commission erred by refusing access to documentation about the pesticide glyphosate.

On January 27, 2015, the European Union (EU) Standing Committee on Plants, Animals, Food and Feed agreed to a proposed list of 77 pesticide active substances to be classified as Candidates for Substitution (CFS). The draft list of CFS is available online. A Question and Answer (Q&A) document regarding the CFS list is available online. Additional information regarding the proposed list is also available online.
This list is an important and long-awaited development under the Plant Protection Product (PPP) Regulation (EC) No. 1107/2009. The Standing Committee clarifies that the CFS active substances are not banned and that approved CFS active substances will remain on the EU market, although there are potentially significant consequences for those listed active substances. Most challenging is the requirement that Member States do the following for new applications for authorization of PPPs containing CFS active substances that are submitted after August 1, 2015: (1) conduct a comparative assessment when evaluating an application for authorization for a PPP containing an active substance approved as a CFS; and (2) not authorize or restrict the use of a PPP containing a CFS for use on a particular crop where the comparative assessment weighing up the risks and benefits demonstrates that safer alternatives exist. In addition, substances not evaluated by the Standing Committee (e.g., substances approved after January 1, 2013) can be identified as a CFS under Article 24 of the PPP Regulation. In those cases, any approval will be limited to a maximum of seven years, compared to 10 or 15 years for other active substances.
The next step will be review and adoption of the CFS list by the European Commission, and then publication of the list as a Commission Regulation in the Official Journal.

On December 16, 2014, the Center for Food Safety (CFS) and its affiliate the International Center for Technology Assessment (ICTA), along with a coalition of other non-governmental organizations, brought suit in the U.S. District Court for the District of Columbia. The suit concerns a May 1, 2008, petition by these organizations requesting that the U.S. Environmental Protection Agency (EPA) take regulatory action concerning nanoscale silver (nanosilver) products, including classifying nanosilver as a pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Since receiving the CFS/ICTA petition, EPA has taken a number of incremental steps to regulate nanosilver. After inviting comment concerning the petition, EPA referred scientific issues concerning risks from and exposure to nanosilver to the FIFRA Scientific Advisory Panel (SAP), announced that it would treat nanoscale pesticides (including nanosilver) as a separate pesticidal active ingredient, established new registration requirements for several specific nanosilver products, and initiated the registration review process for registered nanosilver products.
Notwithstanding these actions, EPA has not formally responded to the 2008 CFS/ICTA petition, and the petitioners have characterized the steps taken by EPA to date as “toothless.” Rather than contesting the suit, EPA may seek an agreement requiring EPA to respond formally to the petition by a specified date. Perhaps EPA will characterize the regulatory actions taken to date as a partial grant of the petition. On the other hand, many of the nearly 400 nanosilver products that CFS/ICTA claim EPA should regulate under FIFRA have no pesticidal claims or purpose or are being sold and distributed outside of the U.S. With respect to these products, EPA will likely respond that it has no authority to provide the relief sought by the petitioners.
