On Wednesday, federal health officials and Sabra Dipping Company announced that the company has voluntarily recalled 30,000 cases of hummus across the nation. The recall has been made owing to possible Listeria contamination.

Last month, a routine sample of Sabra hummus from a store was tested positive for the Listeria monocytogenes. The US Food and Drug Administration said that there is no evidence that hummus has caused any problem to anyone.

"'The potential for contamination was discovered when a routine, random sample collected at a retail location on March 30th, 2015 by the Michigan Department of Agriculture and Rural Development, tested positive for Listeria monocytogenes", said the company.

Sabra Dipping Co. said that the recall measure is active for five SKUs of Classic Hummus sold nationwide. It said that no other Sabra product has been affected. It also said that customers will be refunded of they return products to the store.

The recall news came following warnings from the US health officials over the weekend with regard to the products from a Blue Bell Creameries' Oklahoma ice cream plant. The plant has been closed due to possible listeria contamination.

The CDC said that listeriosis is a serious infection that happens by having food contaminated with the bacterium Listeria. Health people may suffer from its short-term symptoms like high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea.

Elderly, pregnant women, newborns and people having compromised immune systems are at more risk to be affected with the infection. In severe condition, it can also lead to death.

At least three people have died between January 2014 and January 2015 after becoming sick by Listeriosis at a hospital where Blue Bell products were served. These people were in hospital for other reasons.
