Beth O’Connell Senior Toxicologist

Beth has an MA (Cantab) in Natural Sciences from the University of Cambridge, an MSc in Forensic Science from King’s College London, and is a Registered Toxicologist. She has been a toxicologist at bibra for over eight years, and is skilled in searching for and consolidating data on the mammalian toxicology of chemicals, and assessing these data in the context of human health.

Beth has worked for government agencies, and clients from a range of industrial sectors, including consumer products, food, pharmaceuticals and medical devices. Beth has worked to establish the modes of action (MoAs) of chemical carcinogens, and has established tolerable human exposures by different routes (oral, inhalation, dermal, injection) for both genotoxic and non-genotoxic substances. Over the years, Beth has performed risk assessments on hundreds of chemicals, including additives, flavourings, pharmaceutical impurities, degradants, extractables and leachables. She has also evaluated the safety of a range of different medical devices in compliance with ISO 10993, and has assisted both with REACH work on industrial chemicals and pre-manufacture notice (PMN) submissions for compliance with the US Toxic Substance Control Act (TSCA). Another area of interest is the cosmetics sector, for which Beth has drafted cosmetic product safety reports (CPSRs) under the European Cosmetics Regulation ((EC) 1223/2009), assessing the toxicological properties of individual cosmetics ingredients to ensure that products are safe for human use.

Beth also edits Toxicology and Regulatory News, bibra’s monthly publication summarising critical developments and reports relevant to the field of mammalian toxicology.

Outside of work Beth attends both creative writing and life drawing classes, and is training for her green belt in kickboxing!
