Exponent conducts a variety of exposure and risk assessments
using a number of methods, including proprietary software
systems that are based on probabilistic exposure and risk
assessment models. These technical services are provided
in support of regulatory strategies, product defense and stewardship,
and safety assessments. Regulatory authorities such as EPA,
USDA, NAFTA, and Health Canada have licensed our software.
Our services include:
- Dietary exposure and risk assessment
- Residential/consumer exposure and risk assessment
- Occupational exposure and risk assessment
- Aggregate and cumulative exposure and risk assessment
- Exposure/risk-based ranking assessment
- Microbial risk assessment
- Vulnerability assessment
Dietary Exposure and Risk Assessment
Exponent’s regulatory specialists are best known for
their accomplishments in the area of dietary exposure and
risk assessment. Our database on U.S. food consumption is
regularly updated to contain the most currently available
data, and our proprietary software, DEEM™ and FARE™,
permits rapid and flexible assessments.
Probabilistic Aggregate Exposure and Risk Assessments
Exponent devoted vast resources to the development of a calendar-based
probabilistic model to aggregate dietary and non-dietary exposures
and risks (as mandated under the Food Quality Protection Act
[FQPA] of 1996), and created a model known as Calendex™.
This model has been designed to address the multitude of technical
challenges concerning the aggregation of exposures and risks,
from the application of pesticides to the use of consumer
products and industrial chemicals. Using this proprietary
tool, Exponent’s highly skilled exposure/risk assessors
and statisticians provide clients with highly refined exposure
and risk assessments. Calendex™
has been licensed to EPA, USDA, and Health Canada.
Microbial Risk Assessment
At the request of and in conjunction with FDA, Exponent developed
FARE™ Microbial, a modular
software for conducting probabilistic microbial risk assessment.
This development is an extension of the Novigen Foods Analysis
and Residue Evaluation (FARE™) program, a multi-objective
research program for mining food consumption patterns and
computing exposure distributions. While it incorporates algorithms
developed by FDA for the Listeria monocytogenes risk
assessment, FARE™ Microbial is capable of performing
risk assessment for a variety of food borne pathogens.
