Irish dairy giant Ornua has failed to convince a New York district court judge to dismiss allegations a cancer-linked chemical previously found in its Kerrygold packaging could have migrated to its butter.

Ornua, owner of the Kerrygold butter brand, is facing a class action court case in the US over its use of per-and polyfluoralkyl substances, known as PFAS, in its packaging. The case, which began last year, was taken by Carolyn Winans, who claims that PFAS migrates into food, including butter, when the chemicals are present in the packaging.
