Sabra Dipping Company on Wednesday announced the voluntarily recall of 30,000 cases of its classic hummus from across the United States over a possible threat of Listeria contamination.

The large-scale recall comes amid warnings from the federal health officials against consuming any food products from an Oklahoma ice cream plant of Blue Bell Creameries, which has been temporarily shut down due to a possible contamination with Listeria.

Meanwhile, the US Food and Drug Administration (FDA) on Wednesday said that a trial tested positive for the Listeria monocytogenes. The agency said that it had collected a routine Sabra hummus sample from a store last month which confirmed the contamination. However, no strong evidence has surfaced in the recent times showing the hummus has affected anyone’s health.

The health experts at the US Centers for Disease Control and Prevention (CDC) say Listeriosis is a serious form infection which is caused by the consumption of eatables that are contaminated with the bacterium Listeria. Among the high risk group are newborns and infants, elderly people, pregnant women and those with weaker immune systems. In some cases, the infection can prove to be fatal.

Earlier this month, the health officials in Kansas had confirmed death of three people between January 2014 and January 2015 due to the Listeriosis infection at a hospital that served food products from Blue Bell.

Releasing a statement on Tuesday, Blue ​Bell said that it has not reported any case of illnesses associated with its products.
