If a scientist data are contaminated what is the best source of action?

If a scientist discovers that their data has been contaminated, the best course of action is to immediately halt any further analysis or conclusions based on that data. They should assess the extent of the contamination, document the findings, and communicate the issue to relevant stakeholders. It's crucial to implement corrective measures, such as re-collecting data or applying stricter contamination prevention protocols. Finally, transparency about the contamination and its implications is essential for maintaining scientific integrity.
