Tablet-K is a kosher certification agency that was under the leadership of Rabbi Rafael Saffra until his death in 2009.
Supervision and certification
Tablet-K products are commonly available at Costco, often for dairy and fish products. Many cheeses produced by Cabot Creamery have a Tablet-K hechsher. In 2006, Cabot Creamery expanded its line of kosher products, with some cheeses receiving a Tablet-K certification.
The Tablet-K hechsher is generally not regarded as reliable by Orthodox Jews, with cheeses and meats considered especially problematic, but some Modern Orthodox Jews find them to be acceptable.
