Australia – Salmonella warning – check your eggs

Food Authority NSW Salmonella Eggs Food Poisoning Food Safety

The NSW Food Authority is urging people to check their kitchens for any eggs that are marked with the identifying stamp BEC or BEC115 because they may be contaminated with a particular type of Salmonella.

The stamp BEC or BEC115 will be found on the shell of individual eggs, not on the carton.

NSW Food Authority CEO Dr Lisa Szabo said thanks to mandatory egg stamping required in NSW, the Food Authority has been able to isolate the particular batch of eggs.

“All other eggs are safe to eat, provided people exercise the usual caution required for a special care food like eggs such as washing your hands and avoiding raw egg products particularly if you are a vulnerable population such as the immune compromised, under two or over 70 years of age or pregnant,” Dr Szabo said.

“It is important to know that not all eggs are impacted but if you have any stamped with BEC or BEC115 we recommend as a precaution that you discard them.

“We typically see a rise in Salmonella during the warmer summer months, so this is an opportune time to remind people to practice good hygiene generally when preparing food and to always keep their hands, surfaces and utensils clean and dry before and after handling eggs.”

Salmonellosis symptoms include fever, headache, diarrhoea, abdominal pain, nausea and vomiting. Symptoms usually start around six to 72 hours after the contaminated food is eaten and usually last for four to seven days but can continue for much longer.

If you have immediate health concerns contact your medical professional in the first instance.

NSW Health data indicates that during January 2019, 412 cases of Salmonella infection have been notified, which is similar to the number notified during January in recent years. Children under 5 years of age account for most cases notified this month, although all age groups are affected.

The NSW Food Authority placed a Prohibition Order on the business that produced the eggs earlier in January preventing them from selling eggs while the possible Salmonella contamination was investigated.

“While it is likely that most affected eggs are no longer in the supply chain, it is possible that people may have purchased them earlier and still have some at home in the fridge or pantry,” Dr Szabo said.

“We’d just like people to check and if they do have any eggs stamped BEC or BEC115 to throw them out to avoid any risk of food poisoning.”

Grupo Día, which has 7,400 stores, has recalled a batch of canned sardines in olive oil in Spain and Portugal because of botulinum toxin.

The product comes from Portugal and was distributed in Spain. No illnesses have been reported.

Foodborne botulism, caused by eating food that was improperly processed or held at improper temperatures, is rare but potentially fatal if not diagnosed rapidly and treated with antitoxin.

Grupo Día officials said the withdrawal is a precautionary measure due to a possible sterilization defect.

The Spanish multinational company specializes in the distribution of food, household and personal care products. It operates in Spain, Portugal, Argentina, Brazil and China with almost 7,400 stores.

The Spanish Agency for Consumer Affairs, Food Safety and Nutrition (AECOSAN) issued a statement saying it had learnt that more than 24,500 cans of sardines had been recalled.

UK – Levels of AMR Campylobacter in retail chickens remain steady

FSA

Levels of AMR Campylobacter in retail chickens remain steady

We have published the Year 3 results of a survey to identify the proportion of Campylobacter isolated from the FSA’s UK retail chicken survey that were resistant to a range of antimicrobial agents.

The survey tested a subset of the Campylobacter isolates (Campylobacter jejuni and Campylobacter coli strains) from Year 3 of the UK retail chicken survey for AMR. Analysis was carried out between August 2016 and July 2017 during which 585 Campylobacter isolates from samples of whole, UK-produced, fresh chicken were tested.

Background

The development and spread of antimicrobial resistance (AMR) is a concern worldwide. The use of antibiotics is important in treating infections and preventing disease from arising in both animals and humans. However, the overuse and/or misuse of antibiotics in both animal husbandry and healthcare settings has been linked to the emergence and spread of microorganisms which are resistant to them, rendering treatment ineffective and posing a risk to public health.

The transmission of AMR microorganisms through the food chain is thought to be one of the routes by which people are exposed to AMR bacteria. However, there is uncertainty around the contribution food makes to the problem of AMR in human infections.

This report presents AMR data for a subset of Campylobacter isolates collected as part of the survey of Campylobacter contamination in fresh whole UK-produced chilled chickens at retail sale. There is a continued need to monitor the prevalence and types of AMR bacteria in retail chicken and other foods to inform a baseline and also the risk to public health.

What the results show

Read the report: AMR in Campylobacter from retail chilled chicken in the UK (Year 3: 2016-17)

Overall, the proportions of AMR Campylobacter isolates found in this study were similar to those reported in the previous survey year (July 2015 to July 2016), although the percentage of C. coli isolates with resistance to erythromycin was lower. Multi-drug resistance was similar to that found in the previous survey years.

Differences in levels of ciprofloxacin and tetracycline resistance for isolates from standard and free-range birds were examined. There were no differences within C. jejuni isolates but a higher proportion of C. coli isolates from free-range chickens were resistant, compared to isolates recovered from standard chickens. However, relatively few isolates were tested and this result has not been found in previous surveys.

FSA’s Science lead in Microbiological Risk Assessment, Paul Cook said:

‘While there is evidence that AMR Campylobacter is present on whole fresh chickens sold at retail in the UK, the risk of getting AMR-related infections through eating or preparing contaminated meat remains very low as long as you follow good hygiene and cooking practices.

‘Tackling AMR is a significant priority for the FSA and across UK Government. This survey allows us to monitor AMR Campylobacter in retail chickens over time and overall results have remained stable.’

Year 3 Campylobacter retail chicken survey

The FSA has also published the Year 3 report for the UK retail chicken survey. This report collates the data for August 2016-July 2017 which has previously been published quarterly.

Compared to previous years of the retail survey, the report shows that the average proportion of fresh, whole chicken at retail sale in the UK that are contaminated with a high level of Campylobacter decreased considerably for this period.

Consumer advice

Chicken is safe as long as you follow good hygiene and cooking practices.

  • 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
  • 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
  • make sure chicken is cooked thoroughly and 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.

Research – Prevalence of Norovirus in produce sold at retail in the United Kingdom

Science Direct

Highlights

•

Fresh / frozen raspberries and lettuce were sampled from UK retail outlets over a 13 months, and tested for Norovirus.

•

5.3% of lettuce, 2.3% of fresh raspberry, and 3.6% of frozen raspberry samples were Norovirus-positive.

•

The data raises whether food safety management systems are being effectively implemented in these food supply chains.

Abstract

To acquire data on contamination with Norovirus in berry fruit and salad vegetables in the United Kingdom, one thousand one hundred and fifty two samples of fresh produce sold at retail in the UK were analysed for Norovirus. Of 568 samples of lettuce, 30 (5.3%) were Norovirus-positive. Most (24/30) lettuce samples which tested positive for Norovirus were grown in the UK and 19 of those 24 samples contained NoV GI. Seven/310 (2.3%) samples of fresh raspberries were Norovirus-positive. Most (6/7) of the positively-testing fresh raspberry samples were imported, but no predominance of a genogroup, or any seasonality, was observed. Ten/274 (3.6%) samples of frozen raspberries were Norovirus-positive. The country of origin of the positively-testing frozen raspberry samples was not identified in most (7/10) instances. The collected data add to the currently limited body of prevalence information on Norovirus in fresh produce, and indicate the need for implementation of effective food safety management of foodborne viruses.

Research – Understanding the Relation between Establishment Food Safety Management and Salmonella Risk Factor Violations Cited during Routine Inspections

Journal of Food Protection

Restaurants are a frequent setting for outbreaks and sporadic cases of Salmonella. The relationship among food safety management characteristics, compliance with procedures to reduce Salmonella-associated risk factors (as found during routine inspections), and the likelihood that an establishment has experienced a sporadic Salmonella case was assessed. Individual risk factor violations associated with Salmonella transmission pathways were identified by a literature review. Data from 546 routine inspection reports collected from July 2016 to June 2017, including 25 from restaurants that had experienced a sporadic case of Salmonella, were evaluated. In restaurants with certified food managers, there were fewer observations of Salmonella risk factor reduction procedures that were not in compliance. For establishments that had experienced sporadic cases of Salmonella, the person in charge at the time of an inspection was less likely to have been the establishment’s official certified food manager of record (rate ratio = 0.4, 95% confidence interval = 0.2 to 0.8; P = 0.01), and there was increased likelihood of being found out of compliance for prevention of contamination by hands (rate ratio = 3.7, 95% confidence interval = 1.4 to 8.1; P = 0.001). The results of this study warrant future research on the dynamics of food safety management systems, the effect they have on risk factor violations cited on routine inspection results, and the risk for transmission of Salmonella. Analyzing routine inspection data as hazard surveillance may be useful to identify food establishments at a greater risk for transmitting Salmonella infections.

Research – Predicting the Growth of Listeria monocytogenes and Salmonella Typhimurium in Diced Celery, Onions, and Tomatoes during Simulated Commercial Transport, Retail Storage, and Display

Journal of Food Protection cherry-tomato-pristine-variety

Temperature is arguably the most important factor affecting microbial proliferation in fresh-cut produce. In this study, growth of Listeria monocytogenes in diced onions and celery and Salmonella Typhimurium in diced tomatoes was determined in modified atmosphere packages and snap-fit containers using three fluctuating temperature scenarios for transport, retail storage, and display. As expected, L. monocytogenes growth in diced onions and celery varied depending on the extent of temperature abuse, with exposure to high and intermediate temperature-abuse scenarios generally being growth supportive. A Baranyi primary model with a square-root secondary model for maximum growth rate, and a linear model for maximum population density, were used to estimate Listeria growth under fluctuating temperature. Accuracy and acceptability of the model prediction were evaluated in terms of root mean square error (RMSE) and acceptable prediction zone (APZ), respectively. Overall, growth predictions for L. monocytogenes were more accurate for celery (RMSE, 0.28 to 0.47) than onions (RMSE, 0.42 to 1.53) under the fluctuating temperature scenarios tested. However, both predictions yielded APZ values that ranged from 82 to 100% for celery and 36 to 78% for onions. In contrast, Salmonella Typhimurium populations increased more than 1 log CFU/g in diced tomatoes under the three fluctuating temperature scenarios studied. Overall, these diced products packaged under a high-oxygen atmosphere showed decreased pathogen growth compared with product stored in a passive modified atmosphere. Findings from this study will be particularly useful in assessing the risk associated with consumption of diced celery, tomatoes, and onions and in designing effective packaging strategies to minimize pathogen growth in fresh-cut produce.
