Australia – Food Poisoning on the Increase

smh.com.au

The number of Australians struck down by food poisoning has leapt almost 80 per cent in a decade and the number of outbreaks linked to restaurants has more than doubled, according to the latest government statistics.

In the decade to 2011, the number of Australians affected by food-borne gastroenteritis increased 79 per cent, according to figures from OzFoodNet, the national food-borne disease monitoring network. In 2011, 150 outbreaks affected 2241 people compared  with 86  affecting 1768 people in 2001. The rate of hospitalisation has trebled since 2001.

The figures capture only a fraction of  infections since most   victims don’t go to a doctor, experts say. A 2002 estimate of people  affected by food poisoning put the number at 5.4 million cases of gastro and 120 deaths a year at a cost  of $1.25 billion.

Changing eating habits are  believed to be a leading cause. People  cook less and eat out more, say public health experts, which may partly explain why the food service industry was responsible for more than three-quarters of food poisoning outbreaks in 2011.

USA – Update on the Foster Farms Salmonella Outbreak – Is it Over?

CDCimagesCAYZ5I84

The investigation continues into Salmonella Heidelberg infections likely related to Foster Farms chicken.

As of February  28, 2014, a total of 481 persons infected with seven outbreak strains of Salmonella Heidelberg have been reported from 25 states and Puerto Rico, since March 1, 2013.

38% of ill persons have been hospitalized, and no deaths have been reported.

Most ill persons  (76%) have been reported from California.

The number of reported infections from all seven outbreak strains  of Salmonella Heidelberg returned to baseline levels in January and the  outbreak appeared to be over, as noted in the previous update on January 16,  2014. However, the investigation continued.

Ongoing surveillance identified in February that infections from  two of the previously rare outbreak strains have again exceeded the number of  infections expected to be reported to PulseNet during this time of year.

Epidemiologic, laboratory, and traceback investigations conducted by local, state, and federal officials indicate that consumption of Foster  Farms brand chicken is the likely source of this outbreak of Salmonella Heidelberg infections.

The outbreak strains of Salmonella Heidelberg are resistant to several commonly prescribed antibiotics. Although these antibiotics are not typically used to treat Salmonella bloodstream infections or other severe Salmonella infections,  antibiotic resistance can increase the risk of hospitalization in  infected individuals.

It is not unusual for raw poultry from any producer to have Salmonella bacteria. CDC and USDA-FSIS recommend consumers   follow food safety tips to prevent Salmonella infection from raw  poultry produced by Foster Farms or any other brand.

Research Netherlands – Microbial Risk in Produce

Ingentaconnect

The objective of this study was to evaluate the microbial hazard associated with the consumption of mixed salads produced under standard conditions. The presence of Salmonella, Campylobacter spp., and Escherichia coli O157 in the Dutch production chain of mixed salads was determined. Microbial prevalence and concentration data from a microbiological surveillance study were used as inputs for the quantitative microbial risk assessment. Chain logistics, production figures, and consumption patterns were combined with the survey data for the risk assessment chain approach. The results of the sample analysis were used to track events from contamination through human illness. Wide 95% confidence intervals around the mean were found for estimated annual numbers of illnesses resulting from the consumption of mixed salads contaminated with Salmonella Typhimurium DT104 (0 to 10,300 cases), Campylobacter spp. (0 to 92,000 cases), or E. coli (0 to 800 cases). The main sources of uncertainty are the lack of decontamination data (i.e., produce washing during processing) and an appropriate dose-response relationship.

Recent outbreaks with vegetable or fruits as vehicles have raised interest in the characterization of the public health risk due to microbial contamination of these commodities. Because qualitative and quantitative data regarding prevalence and concentration of various microbes are lacking, we conducted a survey to estimate the prevalence and contamination level of raw produce and the resulting minimally processed packaged salads as sold in The Netherlands. A dedicated sampling plan accounted for the amount of processed produce in relation to the amount of products, laboratory capacity, and seasonal influences. Over 1,800 samples of produce and over 1,900 samples of ready-to-eat mixed salads were investigated for Salmonella enterica serovars, Campylobacter spp., Escherichia coli O157, and Listeria monocytogenes. The overall prevalence in raw produce varied between 0.11% for E. coli O157 and L. monocytogenes and 0.38% for Salmonella. Prevalence point estimates for specific produce/pathogen combinations ranged for Salmonella from 0.53% in iceberg lettuce to 5.1% in cucumber. For Campylobacter, this ranged from 0.83% in endive to 2.7% in oak tree lettuce. These data will be used to determine the public health risk posed by the consumption of ready-to-eat mixed salads in The Netherlands.

USA – Expanded Recall – Cheese – Sour Cream – Listeria monocytogenes

Update: On February 23 and 25, 2014 Roos Foods issued press releases for
the recall of our cheese products. This recall has been expanded to include all
product sizes and containers of Santa Rosa de Lima Queso Duro Blando (hard
cheese), and Mexicana Queso Cojito Molido. This update also serves as
additional clarification that ALL sizes and containers of the cheese products
previously identified are being recalled (Amigo, Anita, Mexicana, and Santa
Rose de Lima brands of: Cuajada En Terron, Cuajada/Cuajadita Cacer, Cuajada
Fresca, Queso Fresco Round, and Queso Duro Viejo (hard cheeses), Requeson,
Queso de Huerta and Quesco Fresco. These cheeses were packaged in various sized clear plastic wrapped Styrofoam trays, clear plastic wrapped, clear plastic
vacuum package, and clear rigid plastic containers.
Roos Foods of Kenton, DE is voluntarily recalling the above products because
they have the potential to be contaminated with Listeria monocytogenes, an
organism which can cause serious and sometimes fatal infections in young
children, frail or elderly people, and others with weakened immune systems.
Although healthy individuals may suffer only short-term symptoms such as high
fever, severe headache, stiffness, nausea, abdominal pain and diarrhea,
Listeria infection can cause miscarriages and still births among pregnant
women.
Out of an abundance of caution, Roos Foods is also recalling all product sizes
and containers of Santa Rosa de Lima Crema Salvadorena Cultured Sour Cream,
Santa Rosa de Lima Mantequilla de Bolsa Tradicion Centroamericana, Crema Pura Mexicana Cultured Sour Cream, La Chapina Crema Guatemalteca Guatemalan StyleCream, and Amigo Brand Crema Centroamericana Cultured Sour Cream. These sour creams were packaged in various sized white plastic tubs, clear plastic bags, clear plastic pouches, and clear plastic jars.

Products were distributed through retail stores in Delaware, Maryland, New
Jersey, New York, Virginia and Washington, DC.

Customers should destroy all lots of the above listed brand named products. If
you have any further questions please contact Virginia Mejia phone number
302-653-0600, Monday thru Friday from 9:00 AM to 3:00 PM EST.
