Reviewer 2 Report

- Legislation section, multiple paragraphs were created to introduce each country's legislation; they should be integrated in each paragraph for each country to make it easier to follow.

- It should include a table with the permissible concentrations of each PFAS in food or other products in each country. Similar, a table of it contamination in enviromental and food (with difference kind of source or food, which PFSA detected, how many, etc) should be provided. 

- The sections "Toxicity/Toxicological Effects" and "Contamination" should appear before the section "Analytical Technique."

- The authors should give their conclusion or scientific understanding for each issue at the end of each section.

- A figure summarizing the analytical technique strategy should be supplied.
