A woman in California also lost a fetus from the disease that US health officials have linked to Yu Shang Food Inc

A listeria outbreak linked to ready-to-eat meat and poultry products from a South Carolina food processor has caused 11 illnesses in four states, with nine hospitalizations, according to the US Centers for Disease Control and Prevention (CDC).

A woman who was pregnant with twins was also sickened. Both of the fetuses died, but listeria was found in a sample from only one.
