The microbial world is critical for life on earth, providing many benefits to humankind. Yet it can also cause great suffering and economic damage. Geosyntec is committed to applying its scientific and engineering acumen to help our clients navigate challenges posed by harmful microorganisms. As a recent example, the global pandemic affected all aspects of our communities and businesses. Geosyntec’s experts supported universities, senior- and child-care facilities, governments, manufacturers, food processors, and retail clients. These same clients will be at risk as new pathogens emerge. The poultry and dairy industries face similar economically devastating challenges from highly pathogenic avian influenza viruses, which could also carry serious human health risks from cross-species transmission. To quickly and appropriately respond to new pathogens and variants, our experts offer profound experience to address environmental health threats such as COVID-19 and its variants, anthrax (Bacillus anthracis), Legionnaires’ disease (Legionella pneumophila), mold, and other pathogens. Additionally, we also support agricultural industries, offering surveillance for early pathogen detection, sanitation technologies, and engineering controls to mitigate losses to flocks and herds and their products such as eggs, milk, and meat. No matter the pathogen, clients turn to us to help reduce economic disruption, protect their employees and assets, and support efforts to combat many types of pathogens. We offer a wide range of services to help clients effectively respond to pathogens.

Product manufacturers, marketers, and clients are challenged with significant investments of time and money when developing and launching pesticidal products. Critical decisions on marketing, efficacy claims and pesticidal mode of action determine regulatory registration track, required testing programs, and the ultimate path to market. Geosyntec has broad experience in the regulation and registration of all classes of pesticide products (conventional pesticides, biopesticides, and antimicrobials) and provides science-based, business-focused support to guide clients through decision making, product positioning, and ultimately registration and market introduction. Geosyntec's Pesticide Product Services supports clients with insightful, innovative solutions. Geosyntec's team of toxicologists, risk assessors, regulatory specialists, and chemists have extensive experience and knowledge of pesticide testing, submission, and label requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). We know how to position projects for efficient registration review and processing, and how to avoid misinterpreted guidance, labels, and efficacy claims that can add months to review timeframes and can significantly increase costs. We can assist with navigating all areas of FIFRA including: Preparing a product/pesticide registration strategy Meeting with and advocating on behalf of companies with regulators Developing and submitting FIFRA registration packages, renewals, and label updates Product label content development Preparing inert ingredient petitions Developing data waivers and rationales Scoping, placing, and monitoring product toxicity, physical characteristic, and efficacy studies Responding to regulator requests Pesticide device strategy, claims, data, and regulatory tracking State-level registrations Geosyntec and our wholly-owned SiREM lab manage data generation for new product registrations and amending existing products, particularly for antimicrobial products. Geosyntec and SiREM provide in-depth analytical consulting support covering toxicology studies and antimicrobial efficacy testing. SiREM provides Good Laboratory Practice (GLP) standard antimicrobial testing (i.e., bacteria and virus) to support required testing and methods under FIFRA. The Geosyntec and SiREM team allows for expert level review and strategy development of testing programs, as well as expedited access to efficacy testing, which can save months in registration timelines.
