Research – Campylobacter Thermal Survival

IngentaConnectCampylobacter

In Europe, Campylobacter is the leading reported cause of bacterial foodborne infectious disease. Quantifying its ability to survive at chilled and ambient temperatures and identifying the factors involved in variation in its survival may contribute to the development of efficient risk management strategies. A data set of 307 inactivation curves collected from the literature and the ComBase database, combined with 388 experimental curves, was analyzed with a log-linear model to obtain 695 D-values (time for 1 log inactivation). An additional 146 D-values collected from the literature or ComBase were added to the data set, for a total of 841 D-values. Because data were collected from different studies, the experimental conditions were somewhat heterogeneous (e.g., type of media or strain used). The full data set was then split into 19 different study types on which a meta-analysis was performed to determine the effect of temperature (range 0 to 42°C), Campylobacter species (C. coli and C. jejuni), and media (liquid media or meat matrix) on the survival ability of Campylobacter. A mixed-effects model, in which the study type and bacterial species were considered as random effects and the media and temperature as fixed effects, was run using a Bayesian approach. Overall, the model gave satisfactory results, with a residual standard deviation of 0.345 (the model response was the log D-value, expressed in days). In addition, the survival of Campylobacter was greater at 0 than at 42°C, with a log-linear pattern; the z-value (temperature to have a 10-fold decrease of D-value) was estimated to be 26.4°C (95 % interval: 23.9 to 29.4°C). Despite a significant media-species interaction term, it was established that both species were more resistant on the meat matrix than in liquid media. These results may be used to understand how Campylobacter can survive along the food chain, particularly in chilled environments, and consequently be transferred to other foodstuffs.

USA – Foster Farms Salmonella Chicken Over 300 Sickened

Food Poisoning Bulletin

The Centers for Disease Control and Prevention (CDC) now says that 31 people in 20 states and Puerto Rico have been infected with seven outbreak strains of Salmonella Heidelberg. But no recall. That is an increase of 39 from the last update on October 87, 2013.

Forty-two percent of ill persons have been hospitalized. No deaths have been reported. Seventy-three percent of patients are from California. Epidemiologic, laboratory, and traceback investigations by local, state, and federal officials indicate that consumption of Foster Farms chicken is the likely source of this outbreak.

USA – Salmonella Issues – Mexican Restaurant – Fundraising Dinner – Raw Chicken

Food Poisoning Bulletin

Many Americans are unaware that Salmonella poisoning causes real illness with real costs. In the U.S., direct medical cost associated with the treatment of Salmonella poisoning total about $1 million each day, according to the Centers for Disease Control and Prevention (CDC).

“We need to understand the true burden of Salmonella in our food,’’ said Fred Pritzker, a national food safety lawyer, who is publishes Food Poisoning Bulletin. “If we don’t raise awareness, we’ll never get the interventions we need to stop food poisoning.’’

Each year, about 1.5 million Americans are sickened by Salmonella poisoning.

Food Poisoning Bulletin

Public health officials in Illinois and Kentucky are investigating separate outbreaks of Salmonella associated with independent Mexican restaurants. Combined, the Hacienda Don Villo outbreak in Channahon, Illinois, and the Casa Mexicana outbreak in Madisonville, Kentucky, have sickened about 50 people. In Kentucky, one of the outbreak patients has died.

“Every outbreak of Salmonella carries the prospect of life-long illness for unsuspecting families,’’ said Fred Pritzker, founder of national food safety law firm Pritzker Olsen Attorneys. Pritzker said too many people downplay the burdens of Salmonella infection, which can trigger an assortment of long-term illness in some patients. In others, Salmonellosis resolves itself with no medical attention and the illness is over.

Food Poisoning Bulletin

Several news outlets are reporting that a Salmonella outbreak in Limestone County, Alabama is associated with an annual bean dinner fundraiser in Athens at the First Baptist Church Family Life Center, held by the Limestone County Foundation on Aging. At least six people have been confirmed ill with the pathogenic bacteria.

The dinner was held on Friday night, October 4, 2013. The hospital then saw “dozens of people” over the weekend with symptoms including diarrhea, vomiting, and nausea. The Alabama Department of Public health is now involved and will testing food that is left over from the meal.

Food Safety News

USDA’s Food Safety and Inspection Service (FSIS) issued a public health alert Monday after an estimated 278 illnesses in 18 states caused by Salmonella Heidelberg were linked to consumption of raw chicken produced at three Foster Farms facilities in California.

FSIS said while the illnesses had not been been linked to a specific product or production period, raw chicken from the company’s California facilities bear one of the these establishment numbers inside a USDA mark of inspection or elsewhere on the package: “P6137,” “P6137A,” and “P7632.” The products were mainly distributed to retail outlets in California, Oregon and Washington state.

USA – Vibrio Poisoning in Florida 2013

Food Safety NewsV

At least 27 Floridians have been sickened this year – and nine have died– from infections of Vibrio vulnificus, a deadly bacterium that lives in warm seawater and is commonly associated with eating raw oysters and other shellfish. The figure came from a news release published last week by the Florida Department of Health.

USA – FDA Recall- Bell Peppers – Salmonlla

FDASalmonella

Orange County Produce, LLC (“OC Produce”) is voluntarily working with the Food and Drug Administration (“FDA”) and California Department of Public Health (“CDPH”) to coordinate a recall of fresh red and green Bell Peppers for potential contamination with Salmonella. The FDA has advised that a random sample of OC Produce Bell peppers has tested positive for Salmonella.

Salmonella is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis and arthritis.
