Does total viable count form part of any health and safety regulations?

TVC testing is not a specific legal requirement under UK health and safety law, but it is often used to comply with broader hygiene and contamination control standards. In industries such as healthcare, food production, and pharmaceuticals, TVC supports compliance with regulatory frameworks such as HACCP, GMP, ISO standards, and HSE guidance for water hygiene. It provides documented evidence of microbial control in critical environments.
