126 more people sickened with Salmonella after eating tainted beef

A total of 126 more people have been sickened by a strain of Salmonella Newport in an outbreak tied to JBS Tolleson, Inc. beef products, and three more states are affected, according to an outbreak update yesterday from the Centers for Disease Control and Prevention (CDC).

The outbreak has now grown to 246 Salmonella illnesses in 25 states related to this outbreak. Fifty-nine patients have been hospitalized, but there have been no deaths.

The CDC said symptom-onset dates ranged from Aug 5 to Oct 16 of this year. Of 137 people interviewed, 123 (90%) reported eating ground beef at home.

"Officials in Arizona collected an unopened package of ground beef from an ill person's home. The outbreak strain of Salmonella Newport was identified in the ground beef. Whole genome sequencing showed that the Salmonella identified in the ground beef was closely related genetically to the Salmonella in samples from ill people," the CDC said.

On Oct 4, JBS Tolleson, of Tolleson, Ariz., recalled 6.9 million pounds of beef products that were produced and packaged from Jul 26 to Sep 7, 2018. The beef was distributed to a number of sellers, including Winn-Dixie, Walmart, and Sam's Club.

Jennie-O recalls ground turkey over possible Salmonella contamination

Jennie-O Turkey Store Sales, LLC, of Barron, Wisc., announced a recall of 91,388 pounds of raw ground turkey products that may be associated with an outbreak of illnesses caused by Salmonella Reading, according to a press release from the United States Department of Agriculture's Food Safety and Inspection Services (FSIS).

The raw ground turkey products were produced on Sep 11 and include 1-pound packages of ground turkey, taco-seasoned turkey, and Italian-seasoned turkey with "use by" dates of Oct 1 and Oct 2. The products were shipped to retailers across the country. Investigators traced the Salmonella strain to in an unopened package of turkey from an Arizona patient's home.

"FSIS, the CDC, and state public health and agriculture partners, have been working together on an illness cluster involving 164 case-patients in 35 states. Patients have reported eating different types and brands of turkey products purchased from many different stores, handling raw turkey pet food and/or raw turkey, or working with live turkeys or living with someone who handled live turkeys," FSIS said in a statement released yesterday.

FSIS warned consumers to check frozen ground turkey and throw away any recalled products.

Papua New Guinea, Nigeria record new polio cases

Both Papua New Guinea and Nigeria recorded new polio cases this week, according to the latest update from the Global Polio Eradication Initiative (GPEI).

In Papua New Guinea, one new case of vaccine-derived poliovirus type 1 (cVDPV1) was recorded in East Sepik province, Angoram district. The patient first reported paralysis symptoms on Sep 26. The new cases raises Papua New Guinea's year-to-date cVDPV total to 22. The cases represent Papua New Guinea's first polio outbreak in nearly two decades.

In Nigeria, two circulating vaccine-derived poliovirus type 2 (cVDPV2) cases were reported this week. One case was in Katsina state, and the other in Kaduna state (part of the ongoing Jigawa outbreak). The new cases raise Nigeria's year-to-date total to 25.

"As the year draws to a close, endemic and outbreak countries are making concerted efforts to eradicate the last strong holds of polio, by conducting large-scale immunization activities before the end of the year," GPEI noted.

Low-path H5N2 avian flu found in another Minnesota turkey flock

Expanded surveillance near the site of recent low-pathogenic H5N2 avian flu detections at Minnesota turkey farms has turned up one more affected flock, according to an update yesterday from the World Organization for Animal Health (OIE).

The latest outbreak began on Nov 12 at a farm in Kandiyohi County in the central part of the state where the virus was recently found on other turkey facilities. The farm houses 89,600 birds, which will be depopulated through controlled marketing.

The strain was first detected in the middle of November, and genetic sequencing has suggested that the virus is related to a North American wild bird low-pathogenic H5N2 lineage.

USDA launches poultry biosecurity campaign

In other avian flu developments, the US Department of Agriculture (USDA) today launched a new biosecurity campaign aimed at preventing the spread of infectious diseases in commercial in backyard poultry. In a statement, it said given the devastating avian influenza outbreaks in 2014-2015 and this year's outbreak of Newcastle disease, "the timing is right for everyone in the poultry community to work together to protect the health of our nation’s flocks."

Titled "Defend the Flock," the campaign combines and updates two earlier campaigns that target poultry sectors.

Jack Shere, DVM, PhD, the USDA's chief veterinary officer, said though the earlier campaigns were successful, combining them emphasizes shared responsibility and improves the USDA's ability to promote biosecurity practices. The USDA launched a new web page for the campaign and will hold a webinar to share more details about the updated resources.
