Public health concern? STEC in swine

This descriptive longitudinal study was conducted to investigate the fecal shedding of Shiga toxin-producing E. coli (STEC) in finishing swine and to characterize the swine STEC isolates that were recovered.

swine.stec.jan.15Three cohorts of finishing swine (n = 50/cohort; total 150 pigs) were included in the longitudinal study. Individual fecal samples were collected every 2 weeks (8 collections/pig) from the beginning (pig age 10 weeks) to the end (pig age 24 weeks) of the finishing period. STEC isolates were recovered in at least one sample from 65·3% (98/150) of the pigs, and the frequency distribution of first-time STEC detection during the finishing period resembled a point-source outbreak curve.

Nineteen O:H serotypes were identified among the STEC isolates. Most STEC isolates (n = 148) belonged to serotype O59:H21 and carried the stx2e gene. One O49:H21 STEC isolate carried the stx2e and eae genes. High prevalence rates of STEC during the finishing period were observed, and STEC isolates in various non-O157 serogroups were recovered. These data enhance understanding of swine STEC epidemiology, and future research is needed to confirm whether or not swine STEC are of public health concern.

Norovirus in seaweed

In February 2012, an outbreak of gastroenteritis was reported in school A; a successive outbreak was reported at school B. A retrospective cohort study conducted in school A showed that seasoned green seaweed with radishes (relative risk 7·9, 95% confidence interval 1·1–56·2) was significantly associated with illness.

seaweed-saladSimilarly, a case-control study of students at school B showed that cases were 5·1 (95% confidence interval 1·1–24·8) times more likely to have eaten seasoned green seaweed with pears. Multiple norovirus genotypes were detected in samples from students in schools A and B. Norovirus GII.6 isolated from schools A and B were phylogenetically indistinguishable. Green seaweed was supplied by company X, and norovirus GII.4 was isolated from samples of green seaweed.

Green seaweed was assumed to be linked to these outbreaks. To our knowledge, this is the first reported norovirus outbreak associated with green seaweed.

Salmonella positive: Oma’s Pride recalls Purr Complete Feline Poultry Meal

Oma’s Pride of Avon, CT is recalling Purr-Complete Feline Poultry Meal because it has the potential to be contaminated with Salmonella. 

salm.pet.food.jan.15Salmonella can affect animals eating the products and there is risk to humans from handling contaminated pet products, especially if they have not thoroughly washed their hands after having contact with the products or any surfaces exposed to these products.

Purr-Complete Feline Poultry Meal was distributed nationwide through retail stores, distributors, and directly to consumers. Purr-Complete Feline Poultry Meal is sold frozen.  It is packaged in clear 12 oz. (UPC: 8 79384 00017 9) and 2 lb. (UPC: 8 79384 00018 6) plastic packaging under the Oma’s Pride brand as a poultry blend with code #1524.  It was manufactured on September 12, 2014 with a use by recommended date of September 12, 2015.  

There have been no illnesses reported to date.

The recall was as the result of a routine sampling program by Pesticide and Plant Pest Management Division of the Michigan Department of Agriculture and Rural Development resulting in a positive test for Salmonella. Oma’s Pride has ceased the production and distribution of the product as FDA and the company continue their investigation as to what caused the problem.

Cost-benefit analysis for USDA FSIS’ implementation of its non-O157 STEC testing

FSIS has estimated the cost to the regulated industry and FSIS associated with the implementation of its non-O157 STEC testing on beef manufacturing trimmings, based on Agency testing data and information collected through the FSIS 2013 Pathogen Controls in Beef Operations Survey.

cost.benefitWe also assessed the benefits associated with the new testing. In addition, we estimated the cost and examined benefits of expanding its non- O157 STEC testing to ground beef and ground beef components other than beef manufacturing trimmings. The Agency concludes that the costs for sampling and testing are low and believes that the benefits justify the costs. However, FSIS was not able to quantify the benefits of expanding the testing.

Over 18.m pounds of products recalled in 2014 – USDA-FSIS

Almost 18.7m pounds of products were recalled last year, according to the U.S. Department of Agriculture’s Food Safety Inspection Service (USDA-FSIS).

Mick Fleetwood barfs, cutting concert short

Midway through Fleetwood Mac’s Pinnacle Bank Arena concert Saturday night, in Lincoln, Nebraska, drummer Mick Fleetwood suddenly became ill.

mick-fleetwood1“Mick is really sick,” Stevie Nicks told the crowd, adding that Fleetwood was backstage throwing up. “We feel terrible, but we can’t really make him play. Give us a minute, and we’ll figure out what to do.”

That turned out to be playing two more songs.

A drum tech named Steve took over Fleetwood’s kit for “Go Your Own Way,” which is usually the song the band plays before two encores.

Then, after a short break, Christine McVie returned to the stage at a grand piano, playing and singing “Songbird” accompanied by guitarist Lindsey Buckingham.

“Poor old Mick is really sick,” McVie said. “I sing this for him and for all of you.”

“Songbird” has been the final song on the band’s “On With the Show” tour, usually capping a 2½ hour show. Saturday’s truncated set ran just over 90 minutes.

Samples ‘satisfactory’ for Salmonella in Hong Kong

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department has recently completed a targeted food surveillance project on Salmonella in ready-to-eat food. Results showed that all the 800 samples tested were satisfactory.

salmonella.eggs“The Centre collected the samples from over 600 different locations, including retail outlets and food factories, for testing of Salmonella. The samples included cut fruit and salad; meat, poultry and their products (such as ham, shredded chicken, siu-mei and lo-mei); dishes containing eggs (such as pudding and fried rice with eggs); and other food (such as jellyfish and other Chinese cold dishes),” a spokesman for the CFS said today (January 20).

Salmonella is the leading cause of food poisoning locally.
In the past three years, about 40 confirmed food poisoning outbreaks related to Salmonella were recorded by the Centre for Health Protection of the Department of Health, which accounted for about 27 per cent of all confirmed food poisoning outbreaks recorded. Salmonella is often found in the intestinal tract of humans and animals and will be released through defecation. Hence, Salmonella is more commonly found in food of animal origin, including eggs, meat, poultry and raw milk.

Contamination is another means to disseminate Salmonella into other food such as vegetables and fruits. Furthermore, food may be cross-contaminated during processing or preparation if it is not properly handled.

Food safety is a shared responsibility.
All those involved in the food production chain – from farms and manufacturers to food handlers and consumers – should put in place safety measures. For example, food handlers and consumers are advised to apply the following “Five Keys to Food Safety” when handling and preparing food:
Choose Wisely
* Obtain food and food ingredients from approved and reliable sources; and
* Use fresh and wholesome food ingredients and check the quality of the ingredients upon receipt.
Keep Clean
* Wash hands with soap and water before handling food, after handling raw meat or poultry and after engaging in any activities that may contaminate hands (e.g. going to the toilet; handling rubbish, soiled equipment or utensils and money; and carrying out cleaning duties).
cantaloupe.salmonellaSeparate Raw and Cooked Food
* Use two separate refrigerators for storing raw food and cooked or ready-to-eat food as far as practicable;
* If raw food and cooked or ready-to-eat food have to be stored in the same refrigerator, store food in containers with lids to avoid contact between raw food and ready-to-eat or cooked food.
Raw food should be stored below ready-to-eat or cooked food in the refrigerator to prevent juices of raw food from dripping onto ready-to-eat or cooked food; and
* Use separate utensils to handle raw food and cooked or ready-to-eat food.
Cook Thoroughly
* If possible, use a food thermometer to check whether the core temperature of food reaches at least 75 degrees Celsius.
Safe Temperature
* Keep cold food at or below 4 degrees Celsius and hot food above 60 degrees Celsius; and
* Never leave cooked food at room temperature for more than two hours.

Dozens sickened: Sushi source of another Salmonella outbreak in Brisbane

Fresh off the Salmonella-in-deep-fried-ice-cream  outbreak which sickened at least 130 people in Brisbane, health types fear there could be more victims of food poisoning after dozens of people became sick from eating sushi sold in Asian grocery stores in Brisbane.

Could Clostridium difficile be transferred by meat?

Spores of toxigenic Clostridium difficile and spores of food-poisoning strains of Clostridium perfringens show a similar prevalence in meats. Spores of both species are heat resistant and can survive cooking of foods. C. perfringens is a major cause of foodborne illness; studies are needed to determine whether C. difficile transmission by a similar route is a cause of infection.

Campylobacter: Raw milk from Washington creamery recalled

Some batches of raw milk from the Old Silvana Creamery in Arlington are being recalled out of concern they may be contaminated with Campylobacter.

Old Silvana CreameryThe recall affects raw milk from the farm with expiration dates of Jan. 23 and Jan. 24, according to Jim Sinnema, who manages the farm.

The milk is sold in 15 stores in Western Washington. The creamery produces several hundred gallons of raw milk a week, he said.

The recall, announced Monday evening, was launched after an independent lab discovered Campylobacter in a routine weekly sample sent to a laboratory for testing, Sinnema said. It had an expiration date of Jan. 23. As a precaution, raw milk from Old Silvana Creamery with an expiration date of Jan. 24 also was recalled, Sinnema said.
