Listeriosis is a disease caused by the bacterium listeria monocytogenes, with pregnant women, newborns, elderly and people with weakened immune systems most susceptible. Tiger Brands has been ordered to recall products including its Enterprise polony, a ready-to-eat form of finely ground meat, and frankfurters.
RCL said it was taking the precautionary measures of suspending production of its Rainbow Polony brand and is in the process of recalling the products.An investigation of RCL’s Wolwehoek production facility is under way, after some polony products tested positive for listeria, although not the type identified as being responsible for the outbreak, the company said.
