After the company that supplied Sargento with Longhorn Colby Cheese—Deutsch Kase Haus—told Sargento that its product might be contaminated with Listeria monocyctogenes, Sargento issued a recall Sunday.

No illnesses have been reported yet.

Sargento is recalling these two lines of cheeses:

• Sargento Ultra Thin Sliced Longhorn Colby, 6.84 oz., UPC 4610000228, with “Sell By” dates of “12APR17B” and “10MAY17B”
• Sargento Chef Blends Shredded Nacho & Taco Cheese, 8 oz., UPC 4610040041, with “Sell By” dates of “H14JUN17” and “H12JUL17″

“Out of an abundance of caution,” Sargento has also issued recalls for five other product lines that were packaged in the same place as the two above:
