It is based on Good Laboratory Practices (GLP), a set of essential guidelines that ensures the absolute reliability of the tests conducted on these products before they are brought to market.
Their implementation addresses several major challenges:
- Data reliability: These measures prevent data tampering and ensure full traceability of results related to toxicity and environmental impact.
- Health and environmental safety: Authorities rely on this data to assess potential risks to human health, wildlife, and vegetation.
- Mutual Acceptance of Data (MAD): A GLP study conducted in one OECD member country is recognised by the other member countries, thereby avoiding duplicate animal testing.
- Saves time and money: International acceptance of data streamlines regulatory procedures and accelerates access to international markets.
For a study to comply with GLP, it must meet five strict criteria:
- Qualified staff: Employees who are trained, competent, and have clearly defined responsibilities.
- Suitable facilities and equipment: Appropriate facilities and equipment that are regularly maintained, inspected, and calibrated.
- Standard operating procedures (SOPs): Written instructions that ensure the standardisation of tasks and the reproducibility of tests.
- Archiving: The secure storage of data, reports, and, when necessary, samples.
- Quality assurance: an independent internal audit that verifies compliance with GLP principles throughout the study.
For more than 30 years, the CRA-W has been GLP-certified and has developed recognised expertise in the field of plant protection products and biocides. Our teams conduct studies that meet international regulatory requirements and generate the data needed to submit applications for authorisation or authorisation renewal.
Our laboratories characterise plant protection products and biocides, evaluate the quality of treatments applied to various media (seeds, mosquito nets, etc.), and determine the residues present in foodstuffs.
