Thumb Oilseed Recalls Soy Flour (Utilized To Manufacture Human and Animal Food) Due To Salmonella Contamination. Salmonella is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Salmonella can affect animals eating the product and there is risk to humans from handling contaminated products. Especially if they have not thoroughly washed their hands after having contact with the product or any surfaces exposed to these products. Healthy persons infected with Salmonella often experience fever, diarrhea, nausea, vomiting and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe or chronic illnesses. Animals with salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever, and/or vomiting. Some animals will have only decreased appetite, fever and abdominal pain. Infected but otherwise healthy animals can be carriers and infect other animals or humans. If your animal has consumed the recalled product and has these symptoms, please contact your veterinarian.
