WASHINGTON — A peanut butter recall that began this past weekend has been expanded to include 76 varieties of peanut butter, almond butter, cashew butter, tahini and roasted blanched peanut products made by Sunland, Inc., Portales, N.M. According to the company, products made between May 1 and Sept. 24 may be contaminated with Salmonella.

“There is nothing more important to us than the health and safety of our customers, particularly the many families who enjoy our peanut butter every day,” said Jimmie Shearer, president and chief executive officer of Sunland, Inc.

In an update yesterday, the Centers for Disease Control and Prevention said a total of 30 people have been infected with the outbreak strain of Salmonella Bredeney in 19 states. Four people have been hospitalized, but no deaths have been reported.

The C.D.C. said the illnesses have been linked to Trader Joe’s Valencia Creamy Salted Peanut Butter made with Sea Salt.

Also yesterday, Chattanooga Bakery, Inc., maker of MoonPie and LookOut! branded snacks, announced a voluntary, limited recall of its Peanut Butter Crunch products with “Best By” dates of Feb. 26, 2013; March 25, 2013; and April 29, 2013. Sunland supplies peanut butter to Chattanooga.

“Chattanooga Bakery’s Peanut Butter Crunch products have not been associated with any of the reported illnesses,” the company said. “Regardless, we are taking this precautionary step to protect our customers and their families from any possible risk. Customers who have purchased this item are urged not to eat the product, and to dispose of it or return it to the retailer for a full refund.”
