Summary and Conclusions 

Based on the low frequency and severity of incident cases reported for fluoxastrobin in both IDS 

and SENSOR-Pesticides there does not appear to be a concern at this time that would warrant 

further investigation. The Agency will continue to monitor the incident infom1ation and if a 

concern is triggered, additional analysis wil l be included in the risk assessment.

Detailed Review 

I. ACTION REQUESTED 

This review is intended to fulfill our requirement to docket summaries of incident data that were 

reported to the Agency, as well as to ensure human incident data and the Agricultural Health 

Study (AHS) are part of the problem formulation phase of registration review. Reports of 

adverse health effects allegedly due to a specific pesticide exposure (i.e., an " incident") are 

largely self-reported and therefore, generally speaking, neither exposure to a pesticide or 

reported symptom (or the connection between the two) is validated or otherwise confirmed. 

Typically, causation cannot be determined based on incident data. However, incident 

information can be an important source of feedback to the Agency: incidents of severe outcome, 

or a suggested pattern or trend among less severe incidents, can signal the Agency to further 

investigate a particular chemical or product. Observational epidemiology studies relate the risk 

of disease, e.g. , cancer, and exposure to an agent such as a pesticide product in the general 

population or specific sub-groups like pesticide applicators. 

II. BACKGROUND 

Fluoxastrobin is a fungicide registered for foliar use on peanuts, tuberous and corm vegetables, 

leaf petiole vegetables, fruiting vegetables, and turf, as well as seed treatment for potato, peanut 

and turf. Fluoxastrobin is not an RUP, however, it is labeled for professional pest control 

operators only, not for homeowners. 1 

For this evaluation, both the OPP Incident Data System (IDS) and the Centers for Disease 

Control and Prevention/National Institute for Occupational Safety and Health (CDC/NIOSH) 

Sentinel Event Notification System for Occupational Risk-Pesticides (SENSOR) databases were 

consulted for pesticide incident data on the active ingredient fluoxastrobin (pc code: 028869). 

The purpose of the database search is to identify potential patterns in the frequency and severity 

of the health effects attributed to fluoxastrobin exposure. Fluoxastrobin is not included in the 

AHS, and therefore this study does not provide information for this report. 

III. RESULTS/DISCUSSION 

a. IDS (Incident Data System) 

OPP's IDS includes reports of alleged human health incidents from various sources, including 

mandatory Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) Section 6(a)(2) reports 

from registrants, other federal and state health and environmental agencies, and individual 

consumers. Since 1992, OPP has compiled these reports in IDS. IDS contains reports from 

across the U.S. and most incidents have all relevant product information recorded. Reports 

1 EPA Factsheet, found online at: http://www.epa.gov/pesticides/chem search/reg actions/registration/fs PC028869 01-Nov-05.pdf 

Page 2 of 4 
submitted to the lDS represent anecdotal reports or a llegations only, unless otherwise stated in 

the report. 

IDS records incidents in one of two modules: Main IDS and Aggregate IDS: 

o Main IDS contains incidents resulting in higher severity outcomes and provides 

more detail with regard to case specifics. This system stores incident data for 

death, major and moderate incidents, and it includes information about the 

location, date and nature of the incident. Main IDS incidents involving only one 

acti ve ingredient (as opposed to pesticide products with multiple active 

ingredi ents) are considered to provide more certain information about the 

potential effects of exposure from the pesticide. 

o Aggregate lOS contains incidents resulting in less severe human incidents (minor, 

unknown, or no effects outcomes). These are reported by registrants only as 

counts in what are aggregate summaries. 

For the Main IDS, from January I, 20 l 0 to May 27, 20 15, there was one incident reported 

involving fluoxastrobin. This incident had two affected individuals, one case was classified as 

moderate severity and the other minor severity. Two adult females were on their way to work 

and were sprayed twice by a crop duster. One female developed tingling, throat irritation and her 

chest fel t heavy. The other female claimed she was nauseous all day. 

In Aggregate lDS, from January 1, 2010 to May 27, 20 15, there were 5 incidents reported 

involvi ng fluoxastrobi n. These incidents were classified as minor severity. Overall, there are few 

incidents reported to IDS involving fluoxastrobin. 

b. SENSOR-Pesticides 

The SENSOR-Pesticides database covers 12 states from 1998-20 l 1, although reporting varies 

from state to state. Cases of pesticide-related illnesses are ascertained from a variety of sources, 

including: reports from local Poison Control Centers, state Department of Labor workers' 

compensation claims when reported by physicians, reports from State Departments of 

Agriculture, and physician reports to state Departments of Hea lth. Although both occupational 

and non-occupational incidents are included in the database, SENSOR-Pesticides focuses on 

occupational pesticide incidents, and is of particular va lue in providing that information. The 

state coordinator at each of the 12 respective state Departments of Health conducts case followup activities such as obtaining medical records to verify symptoms and severity. Using 

standardized protocol and case definitions derived from poison center reporting, the state 

SENSOR-Pesticide coordinator enters the incident information into the state-based system which 

is sent to NIOSH annually to be aggregated. 

A review of SENSOR-Pesticides from 1998-201 1 identifies no incidents involving fluoxastrobin. 

c. Agricultural Health Study {AHS) 

The AHS is a high quality, prospective epidemiology stud y evaluating the link between pesticide 

use and various health outcomes including cancer. The AHS includes private and commercial 

Page 3of4 
pesticide applicators and their spouses. If there are Al-IS findings relevant to a particular 

pesticide going through registration review, the Agency will ensure they are considered in the 

problem formulation/scoping phase of the process and, if appropriate, full y reviewed in the risk 

assessment phase of the process. The Al-IS includes information on use of 80 different pesticide 

active ingredients commonly used in agriculture. Fluoxastrobin is not included in the AHS, and 

therefore this study does not provide information for this report. 

IV. CONCLUSION 

Based on the low frequency and severity of incident cases reported for fluoxastrobin in both IDS 

and SENSOR-Pesticides there does not appear to be a concern at this time that would warrant 

further investigation. The Agency will continue to monitor the incident information and if a 

concern is triggered, additional analysis will be included in the risk assessment.
