Cases of Salmonella Saintpaul linked to raw alfalfa sprouts are now up to 35 and the U.S. Food and Drug Administration thinks they can all be traced to one seed supplier.

That seed supplier, based in Kentucky, is voluntarily withdrawing from the market all of its 50-pound bags that have a lot code starting with “032.” All of these bags contain seeds from Italy and may be contaminated.

In addition to details about the withdrawn sprouts, the FDA alert states,

“FDA has no evidence that alfalfa seeds from other lots, or sprouts grown from them, are affected by this market withdrawal… Suppliers who can verify that their products were not sourced from the affected lots may wish to notify their customers; likewise, retailers, restaurateurs, and food-service facilities who have verified the sources of their alfalfa products may wish to notify their customers.”

Businesses that can prove they get food from safe sources on purpose—and didn’t just get lucky with this one—should brag about that, too.
