DIXON — Milk sold in Lake County from a northern Illinois dairy may have been processed without proper pasteurization and state officials are telling consumers to throw it away.
A routine inspection at Ludwig Dairy Products in Dixon found pasteurizing equipment operating improperly, potentially allowing raw milk to be mixed with pasteurized milk and sold in dairy products, according to the Illinois Department of Public Health.
Inspectors found a system-controlled pump, designed to stop the production process if raw milk pressure exceeded pasteurized pressure, was bypassed and replaced with a pump not wired into the controls, according to health officials.
Ludwig is taking its name brand products off store shelves. They are sold mostly in northern Illinois, including Cook, DuPage, Kane, Lake, McHenry and Will counties; and also in Indiana, New Jersey and New York.
No illnesses have been reported in connection with the products, but health officials are recommending Ludwig products not be consumed and be thrown out until the pasteurizing equipment is operating correctly and has been re-inspected.
A drinkable yogurt product sold under the brand name Nuestro Queso is also affected.
Ludwig is working with the health officials to determine the extent of the improper pasteurization, officials said.
Pasteurization is the process of heating raw milk to a high enough temperature for a long enough time to kill illness-causing bacteria, the release said. Raw milk and products made from it (such as cheeses and yogurts) can be contaminated with bacteria that can cause serious illness or death.
Common symptoms can include diarrhea, stomach cramping and vomiting, but can also include kidney failure and paralysis.
