I recently noticed that some Ronzoni pasta does not have the OU as in the past. Instead it has the underlined square k. Does anyone know which certifying agency this is? enter image description here

  • Is it just oven ready lasagna? That's precooked so may have always been a different certification

  • I have oven ready boxes in my house with the OU and on Ronzoni website it says the oven ready pasta is certified by the OU Nov 12, 2019 at 0:26
  • The OU website says the oven ready Ronzoni pasta is certified under the OU so long the OU is on the box. Valid until end of January 2020. Nov 12, 2019 at 0:35

That's 1K Kosher, under the supervision of R' Menahem Hadad in Brussels, Belgium. They are listed on R' Eydlitz's KosherQuest as reliable, although CYLOR.
