The Facilities for Illness Management and Prevention stated Friday that Karoun Dairies, Inc. has voluntarily recalled and stopped manufacturing of a number of cheeses, together with these bought underneath the model names Karoun, Arz, Gopi, Queso Del Valle, Central Valley Creamery and Yanni.

The investigation has not conclusively identified the source, but most ill people interviewed reported eating soft cheese before becoming ill. One miscarriage was reported out of five pregnancy-related cases, and one patient died in Ohio.

The cluster was identified in August 2015 after investigators saw an increase in one of the five rare PFGE fingerprints reported to PulseNet (the national subtyping network of public health and food regulatory agency laboratories coordinated by CDC). “The investigation is ongoing”.

The agency discovered the illnesses as it was tracking a handful of listeria cases this summer. Most of those that fell sick reported consuming Center Japanese, Japanese European, Mediterranean, or Mexican-style cheeses.

Whole genome sequencing maps all of an organism’s DNA.

But Listeria contamination can still happen, as evidenced by the outbreaks at Ohio-based Jeni’s Splendid Ice Creams earlier this year.

In response, of course, Karoun Dairies said, in a news release, they are “working closely with FDA to continue to investigate the problem further”. Infants, the elderly, and those with compromised or weakened immune systems may be particularly impacted by Listeria. It might trigger fever, muscle aches and gastrointestinal signs and may be deadly.

USA cheese maker Karoun Dairies has recalled its cheeses on the back of listeria concerns. It also can cause miscarriage, stillbirth, premature labor, and serious illness or death in newborn babies.

Cheeses sold at Kroger stores in Tennessee are being taken off store shelves.

Those who have purchased any of the recalled cheese products are urged to toss them or return them to the points of purchase for full refunds and to disinfect cutting boards, refrigerator compartments, or other items which may have come in contact with the products.
