J.S. Held’s toxicologists provide support on health-based and environmental matters involving public health, exposure, risk assessment, and characterization.
We are retained by clients to evaluate exposure, contamination, and toxicity to determine any adverse effects on human health or the environment. Our toxicology consulting services include risk mitigation strategies, forensic investigations, regulatory consulting, and expert witness and litigation support.
Our experts conduct forensic investigations to uncover the exact details of food safety, contamination, or quality control issues. We examine foodborne illness outbreaks, find out when and where contamination has occurred, and proactively implement food and beverage assessments to understand vulnerabilities and determine whether food, feed product, or beverages pose any health risks to consumers.
With the legalization of cannabis becoming more widespread, the need for forensic cannabis toxicology investigations is rapidly growing. J.S. Held’s chemists and toxicologists conduct cannabis claim evaluations to investigate intoxication and any adverse effects of cannabis products.
Our toxicologists help resolve questions regarding liability in the alleged over-service of patrons or guests that has led to damage, injury, and/or death.

Held experts who specialize in accident reconstruction, human factors, biomechanical engineering, and digital forensics to provide comprehensive forensic investigations and litigation support.
Microbiology analysis is an essential aspect of any health and safety operation, as it ensures products and procedures are free of germs that could cause contamination or infection. J.S. Held environmental microbiology experts help clients by taking a clinical approach to environmental investigations. Our services include detection, identification, isolation, and confirmation of microbial organisms in a range of environmental settings to determine if microbiological contamination has taken place.
Our team is composed of specialists in exposure modeling, risk assessment, and chemical toxicology who have a breadth of expertise in data interpretation, hazard assessments, and the characterization of substances. J.S. Held provides clients with comprehensive chemical analysis of products, including composition analysis, structural analysis, chemical trace analysis, elemental analysis, morphological analysis, and material validation to determine chemical contamination.
Toxic releases from industrial operations are regulated according to local, state, and federal environmental, health, and safety standards. Health Risk Assessments (HRAs) are required to determine the extent of health risk impacts from new and existing industrial operations emitting toxins. J.S. Held toxicologists offer comprehensive Health Risk Assessments to evaluate the potential health risks from such hazardous materials. We are a leader in using Health Risk Assessments to characterize and quantify pollutants, as well as to accelerate the regulatory closure of contaminated sites where no significant health risks are identified.
