Research – Growth of Salmonella and Other Foodborne Pathogens on Inoculated Inshell Pistachios during Simulated Delays between Hulling and Drying

Journal of Food Protection

During harvest, pistachios are hulled, separated in water into floater and sinker streams (in large part on the basis of nut density), and then dried before storage. Higher prevalence and levels of Salmonella were previously observed in floater pistachios, but contributing factors are unclear. To examine the behavior of pathogens on hulled pistachios during simulated drying delays, floater and sinker pistachios collected from commercial processors were inoculated at 1 or 3 log CFU/g with cocktails of Salmonella and in some cases Escherichia coli O157:H7 or Listeria monocytogenes and incubated for up to 30 h at 37°C and 90% relative humidity. Populations were measured by plating onto tryptic soy agar and appropriate selective agars. In most cases, no significant growth (P > 0.05) of Salmonella was observed in the first 3 h after inoculation in hulled floaters and sinkers. Growth of Salmonella was greater on floater pistachios than on corresponding sinkers and on floater pistachios with ≥25% hull adhering to the shell surface than on corresponding floaters with <25% adhering hull. Maximum Salmonella populations (2 to 7 log CFU/g) were ∼2-log higher on floaters than on corresponding sinkers. The growth of E. coliO157:H7 and Salmonella on hulled pistachios was similar, but a longer lag time (approximately 11 h) and significantly lower maximum populations (4 versus 5 to 6 log CFU/g; P < 0.05) were predicted for L. monocytogenes. Significant growth of pathogens on hulled pistachios is possible when delays between hulling and drying are longer than 3 h, and pathogen growth is enhanced in the presence of adhering hull material.

Research – Salmonella: It’s More Pervasive Than You May Think

In late 2018, the Interagency Food Safety Analytics Collaboration (IFSAC) published a report on foodborne illness source attribution from 1998 through 2016. The report used outbreak data to produce new estimates for foods responsible for foodborne illnesses caused by four pathogens in 2016: Salmonella, E. coli O157, Listeria monocytogenes, and Campylobacter.

While all these pathogens are of concern because of the frequency and/or severity of the illnesses they cause, the results of the Salmonella illness assessment are of particular interest: Unlike the other pathogens which were most often linked to specific foods, Salmonella illnesses were broadly attributed across multiple food categories. As stated in the report, “The attribution of Salmonella illnesses to multiple food categories suggests that interventions designed to reduce illnesses from these pathogens need to target a variety of food categories.” Such interventions should include a combination of detection, prevention, and control.

Food Poison Journal

CDC, public health and regulatory officials in several states, and the U.S. Food and Drug AdministrationExternal are investigating a multistate outbreak of Salmonella Newport infections.

As of April 15, 2019, 13 people infected with the outbreak strain of Salmonella Newport have been reported from 7 states. A list of the states and the number of cases in each is on the Map of Reported Cases page.

USA – Jensen Tuna of Louisiana is Voluntarily Recalling Frozen Ground Tuna Imported from JK Fish, Because it may Potentially be Contaminated with Salmonella


Jensen Tuna of Louisiana is voluntarily recalling frozen ground tuna imported from JK Fish, because it may potentially be contaminated with Salmonella.

The frozen product, individually packaged in clear plastic one-pound bags, is sold in white wax 20 lb. boxes. The product is only sold as a wholesale case with twenty bags in each case. The lot numbers are z266, z271 and z272.

No other tuna products are impacted or part of this recall.

The product was sold to wholesalers in Connecticut, Iowa, Illinois, Minnesota, North Dakota, New York, and Washington. These wholesalers further distribute the product to restaurants and retail locations. The product was distributed from November 30, 2018 to March 15, 2019.

Restaurants and retailers should check with their suppliers and not sell or serve recalled frozen ground tuna and should wash and sanitize locations where recalled ground tuna was stored. Consumers with concerns should ask their restaurants and retailers whether the tuna dish they are purchasing contained the recalled ground tuna.

The voluntary recall is in response to the CDC and FDA’s investigation of 13 illnesses caused by Salmonella, confirmed to date. As of today, the ground tuna samples were found negative for Salmonella.

Salmonella is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Most people infected with Salmonella develop symptoms within 12 to 72 hours after infections, according to the FDA. The illness, marked by diarrhea, fever and abdominal cramps, usually lasts 4 to 7 days.

Please contact Jensen Tuna at 985-868-8809 (Monday-Friday, 8am to 3pm, Central time) or email at with questions.
