USA – Salmonella Outbreak Associated With Restore Public House in La Crosse WI

Food Poisoning Bulletin

A Salmonella outbreak associated with steak tartare served at Restore Public House in La Crosse, Wisconsin has sickened 17 people, Jen Rombalski, Health Director of the La Crosse County Health Department told Food Poisoning Bulletin in an email. Steak tartare is made from beef that is finely chopped, mixed with other ingredients, and served raw.

This food is considered “high risk.” The restaurant prepared it properly, according to public health officials. Restaurants can serve these foods, according to Ms. Rombalski, as long as they post an advisory telling consumers that the food is risky to consume.

USA – FDA Advises Consumers Not to Eat Yellowfin Tuna Steaks from Kroger Retail Stores in Multiple States

FDA

Audience

  • Consumers who recently experienced symptoms of scombroid poisoning after eating yellowfin tuna steaks.
  • Consumers who purchased yellowfin tuna steaks from Kroger retail stores in AL, AR, GA, IL, IN, KS, KY, MI, MO, MS, NE, OH, SC, TN, VA and WV with sell by dates from August 29, 2019 to September 14, 2019.

Product

  • Yellowfin tuna steaks sold at Kroger retail stores in AL, AR, GA, IL, IN, KS, KY, MI, MO, MS, NE, OH, SC, TN, VA and WV with sell by dates from August 29, 2019 and September 14, 2019. The product may be sold as raw yellowfin tuna steaks at the seafood counter or seasoned in store-prepped Styrofoam trays.

Purpose

The FDA is advising consumers to not eat yellowfin tuna steaks from the seafood counter or seasoned yellowfin tuna steaks in store-prepped Styrofoam trays from Kroger retail stores in AL, AR, GA, IL, IN, KS, KY, MI, MO, MS, NE, OH, SC, TN, VA and WV with sell by dates from August 29, 2019 and September 14, 2019 because they may cause scombroid poisoning. Consumers of these products who are experiencing symptoms of scombroid poisoning should contact their healthcare provider. Consumers of these products who have recently experienced symptoms of scombroid poisoning should report their symptoms to their local Health Department.

Symptoms of Scombroid Poisoning

Scombroid poisoning is caused by eating fish that has not been properly refrigerated or preserved and therefore contains high levels of histamine. Scombroid poisoning is most commonly caused by fish that have naturally high levels of the amino acid histidine, which bacteria convert to histamine when the fish is not correctly stored.

Scombroid symptoms usually develop within a few minutes to an hour after eating contaminated fish. They usually resemble an allergic reaction, such as flushing of the face, headache, heart palpitations, itching, blurred vision, cramps, and diarrhea. Symptoms can be treated with antihistamines. Even without treatment, people usually get better within 12 hours.

If you suspect you have symptoms of scombroid poisoning, contact a health professional.

Summary of Problem and Scope

On September 4, 2019, the FDA became aware of multiple scombroid poisoning cases in individuals who consumed tuna steaks purchased from three separate Kroger retail locations in Ohio.  On September 5, 2019, Kroger agreed to remove all yellowfin tuna steaks from their stores in AL, AR, GA, IL, IN, KS, KY, MI, MO, MS, NE, OH, SC, TN, VA and WV as well as  begin notifying consumers who had purchased this product to dispose of or return the product to the store.

The FDA is also working with the distributor to remove any additional product from the market.

Recommendations for Consumers

Consumers who have symptoms of scombroid poisoning should contact their health care provider to report their symptoms and receive care.

To report a complaint or adverse event (illness or serious allergic reaction), you can

FDA Actions

The FDA will continue to work with Kroger, the distributor, and state and local partners to remove all contaminated product from the market.

Research – Growth Potential of Listeria monocytogenes in Chef-Crafted Ready-to-Eat Fresh Cheese-Filled Pasta Meal Stored in Modified Atmosphere Packaging

Journal of Food Protection

ABSTRACT

This study evaluated the growth of lactic acid bacteria (LAB) in a fresh, filled-pasta meal, stored in modified atmosphere packaging and the influence of lactic acid (LA) and pH on the growth of Listeria monocytogenes (Lm). Samples were taken from three lots manufactured by a local catering company and stored at both 6 and 14°C. LAB numbers, LA concentration, pH, and the presence of Lm were evaluated at 1, 4, 6, 8, 10, 12, and 14 days of shelf life and the undissociated LA concentration ([LA]) was calculated. The LAB maximum cell density was greater in the products stored at 14°C than those stored at 6°C (10.1 ± 1.1 versus 5.6 ± 1.5 log CFU/g) and [LA] at 14 days was 9 to 21 ppm at 6°C and 509 to 1,887 ppm at 14°C. Challenge tests were made to evaluate the interference of LAB and [LA] on Lm growth. Aliquots of the samples (25 g) were inoculated at 1 to 10 days of shelf life and incubated at 9°C for 7 days, and the difference between Lm numbers at the end and at the beginning of the test (δ) was calculated. Logistic regression was used to model the probability of growth of Lm as a function of LAB and [LA]. The products inoculated at 1 day of shelf life had δ values between 4.2 and 5.6 log CFU/g, but the growth potential was progressively reduced during the shelf life. Lm growth was never observed in the products stored at 14°C. In those stored at 6°C, it grew only in the samples with LAB <5.7 log CFU/g. LAB interaction might thus inhibit the growth of Lmin temperature-abused products and limit its growth in refrigerated products. Logistic regression estimated that the probability of Lm growth was <10% if LAB was >6.6 log CFU/g or log[LA] was >2.2 ppm. The growth or inactivation kinetic of Lm was investigated with a homogenate of three samples with LAB numbers close to the maximum population density. After an initial growth, a subsequent reduction in the number of Lm was observed. This means that the maximum numbers of Lm might not be detected at the end of the product shelf life.

HIGHLIGHTS
  • MAP and refrigeration were found to be a fruitful hurdle in filled-pasta meals.

  • Higher growth of LAB at 14°C negatively affected the growth potential of Listeria sp.

  • Listeria sp. numbers might decline after an initial growth during the shelf life.

  • The maximum number of Listeria sp. is not always at the end of the product shelf life.

Research – Thermal Inactivation Kinetics of Three Heat-Resistant Salmonella Strains in Whole Liquid Egg

Journal of Food Protection

ABSTRACT

The heat resistance of three heat-resistant strains of Salmonella was determined in whole liquid egg (WLE). Inoculated samples in glass capillary tubes were completely immersed in a circulating water bath and held at 56, 58, 60, 62, and 64°C for predetermined lengths of time. The recovery medium was tryptic soy agar with 0.1% sodium pyruvate and 50 ppm of nalidixic acid. Survival data were fitted using log-linear, log-linear with shoulder, and Weibull models using GInaFiT version 1.7. Based on the R2 and mean square error, the log-linear with shoulder and Weibull models consistently produced a better fit to Salmonella survival curves obtained at these temperatures. Contaminated WLE must be heated at 56, 60, and 64°C for at least 33.2, 2.7, and 0.31 min, respectively, to achieve a 4-log reduction of Salmonella; 39.0, 3.1, and 0.34 min, respectively, for a 5-log reduction; and 45.0, 3.5, and 0.39 min, respectively, for a 6-log reduction. The z-values calculated from the D-values were 3.67 and 4.18°C for the log-linear with shoulder and Weibull models, respectively. Thermal death times presented in this study will be beneficial for WLE distributors and regulatory agencies when designing pasteurization processes to effectively eliminate Salmonella in WLE, thereby ensuring the microbiological safety of the product.

HIGHLIGHTS
  • The thermal resistance of Salmonella strains in WLE was determined at 56 to 64°C.

  • A 5-log reduction at 60 and 64°C required 3.1 and 0.34 min, respectively.

  • The calculated z-value was 3.67°C for the log-linear model and 4.18°C for the Weibull model.

  • These results will assist WLE processors when determining pasteurization regimens.

UK – Major retailers publish Campylobacter results for April-June 2019

FSA

The top nine retailers across the UK have today published their latest testing results on campylobacter contamination in UK-produced fresh whole chickens (covering samples tested from April to June 2019).

The latest figures show that on average, across the major retailers, 3.6% of chickens tested positive for the highest level of contamination. These are the chickens carrying more than 1,000 colony forming units per gram (cfu/g) of campylobacter.

Results

Contamination levels July-September 2018 October-December 2018 January-March 2019 April-June 2019
cfu/g less than 10 58.8% 63.1% 55.4% 59%
cfu/g 10-99 26.7% 22.3% 25.3% 25.3%
cfu/g 100-1000 11% 11.4% 15.8% 12.1%
cfu/g over 1000 3.5% 3.1% 3.5% 3.6%

Results by retailer for April – June 2019

The sampling and analyses are carried out in accordance with protocols laid down by the FSA and agreed by Industry.

Background information

We have been testing chickens for campylobacter since February 2014 and publishing the results as part of a campaign to bring together the whole food chain to tackle the problem. Campylobacter is the most common cause of food poisoning in the UK.

In September 2017 we announced changes to the survey, with major retailers carrying out their own sampling and publishing their results under robust protocols laid down by the FSA. We are continuing to sample fresh whole chickens sold at retail, however, the focus is now on the smaller retailers and the independent market.

Consumer advice

Chicken is safe if consumers follow good kitchen practice:

  • Cover and chill raw chicken – cover raw chicken and store at the bottom of the fridge so juices cannot drip onto other foods and contaminate them with food poisoning bacteria such as campylobacter
  • Don’t wash raw chicken – thorough cooking will kill any bacteria present, including campylobacter, while washing chicken can spread germs by splashing
  • Wash used utensils – thoroughly wash and clean all utensils, chopping boards and surfaces used to prepare raw chicken
  • Wash hands thoroughly with soap and warm water, after handling raw chicken – this helps stop the spread of campylobacter by avoiding cross-contamination
  • Cook chicken thoroughly – make sure chicken is steaming hot all the way through before serving. Cut into the thickest part of the meat and check that it is steaming hot with no pink meat and that the juices run clear.

Majorca – Previous cases at restaurant at the centre of foodborne outbreak

Majorca Daily Bulletin

The Dragon Sushi restaurant in Palma, which was at the centre of the recent foodborne disease outbreak, had received a warning from the health ministry in June.

On that occasion, there was evidence of three people having become ill after eating at the restaurant; all three were found to have salmonella poisoning.

Food safety inspectors went to the restaurant in June and found a number of deficiencies.

These didn’t lead to the restaurant’s closure. The owners were given a warning and instructed to remedy the deficiencies.

Ten days later, the inspectors returned and were satisfied that the issues had been addressed. Sanctioning procedures were initiated against the restaurant. These have yet to be brought to a conclusion. The maximum fine is 5,000 euros.

There are now 94 people who have been affected by the recent outbreak. The number confirmed with having had salmonella poisoning has risen to 26.

The source of the outbreak is still being investigated. When the three cases arose in June, it was apparently not possible to find the source of the poisoning.

The restaurant, which remains closed, faces a second fine of up to 20,000 euros.

USA – Hepatitis A outbreak in Las Vegas: Should vaccinations be required for food workers?

Reno Gazette Virusds

When the number of hepatitis A cases hit peak levels in Southern Nevada in the late 1990s, health officials required all food workers to get immunization shots to prevent the virus that could cause liver damage and lead to death.

But after the number of cases dropped to historic lows in the 2000s, the immunization rule was eliminated.

Today, hepatitis A cases are now on the rise around the U.S. and in Southern Nevada, where health officials reported last week that an infected Las Vegas 7-Eleven clerk handled hot dogs and hot deli items and exposed an unknown number of customers to the virus.

When should immunization shots be mandated to fight disease?

died again a Person after a bath in the Baltic sea. Cause of death is supposed to be like before infection with Vibrios bacteria such as the “image” reported. It is Vibrio-bacteria – so-called rod bacteria, one of which is Cholera.

the course of The disease after an infection with the bacteria is on the route of infection. The bacteria are taken in through the food, it comes to symptoms, as in the case of a gastro-intestinal disease. If the bacteria are transmitted through a wound, this can lead to a serious infection and later to Sepsis.

Killer bacteria still in the water

according to Reports, the Killer bacteria are recorded for several weeks in the waters of the Baltic sea. Currently, these thrive particularly well because the water is over 20 degrees warm. At cooler temperatures the dangerous viruses live mainly on the ground of the sea. And virtually never in contact with people.
