Is fishing line safe?

58 of the 89 fishing line products we graded come back low-concern on our screen and 31 do not. Our grades are model-based assessments built from published materials, ingredient lists, certifications and brand disclosures, not laboratory tests, so they say what we can evidence rather than that anything is safe.

Why Ande Monofilament wins, and what it beats

Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 3 products it beats, so you can see exactly where the 55 points between the top and the bottom of this fishing line ranking come from.
