USA – Luigi’s restaurant in Roanoke Virginia linked to Hepatitis A ill food service worker

Food Poison Journal

Just months ago the Roanoke City and Alleghany Health Districts (RCAHD) announced that RCAHD had identified a total of 50 confirmed primary cases and 2 secondary cases.  There have been at least 31 hospitalizations and unfortunately 4 deaths.

Now the risk of another outbreak is striking the same community.

New details have emerged as part of an ongoing investigation conducted by the Virginia Department of Health. The report involves an employee of Luigi’s restaurant in Roanoke who was recently diagnosed with hepatitis A. New information, obtained today, revealed that the employee may have had limited involvement in handling food prior to the food being cooked before consumption. Cooking food kills the virus that causes hepatitis A, therefore this situation does not meet the criteria of an exposure.

Given the high level of sensitivity of hepatitis A in our community, and out of an abundance of caution, the Roanoke City Health Department is offering hepatitis A vaccine to anyone who ate at Luigi’s between the dates of April 26 – May 17. Hepatitis A vaccinations will be available at the Roanoke City Health Department, 2nd Floor, 1502 Williamson Rd., Roanoke, VA 24012 this week at the following times:

  • Thursday, May 19, 3-6 p.m.
  • Friday, May 20, 8:30 – 11:30 a.m. and 1-4 p.m.

USA – FSIS Issues Public Health Alert for Ready-To-Eat Ham Product Due to Possible Processing Deviation

FSIS USDA

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) is issuing a public health alert for ready-to-eat (RTE) ham product because the product may not be fully cooked due to underprocessing. FSIS is issuing this public health alert to ensure that consumers are aware that this product should not be consumed. A recall was not requested because it is believed that the product is no longer available for consumers to purchase.

The RTE, sliced Black Forest Ham item was produced by Plumrose USA, doing business as Swift Prepared Foods, a Council Bluffs, Iowa establishment, from April 28, 2022 through May 1, 2022. The following product is subject to the public health alert [view labels]:

  • 1-lb resealable plastic packages containing “Great Value Black Forest Ham Water Added” with a “BEST IF USED BY 07/15/22” date.

The product subject to this public health alert bears establishment number “EST. 26C” inside the USDA mark of inspection. This item was shipped to Walmart stores in Illinois, Indiana and Ohio.

The problem was discovered when the firm identified product that did not appear to be fully cooked, which prompted the establishment to perform an investigation and notify FSIS of their findings that the ham was underprocessed.

There have been no confirmed reports of adverse reactions due to consumption of these products. Anyone concerned about an injury or illness should contact a healthcare provider.

FSIS is concerned that some product may be in consumers’ refrigerators or freezers. Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase.

USA – FDA Issues Final Guidance for Seeds Used for Sprouting

FDA

Constituent Update

Download

May 13, 2022

Today the U.S. Food and Drug Administration (FDA) issued a final guidance titled “Reducing Microbial Food Safety Hazards in the Production of Seed for Sprouting: Guidance for Industry.” This guidance outlines FDA’s serious concerns over foodborne illness outbreaks associated with the consumption of raw and lightly-cooked sprouts and provides firms with recommended steps to prevent adulteration throughout the production chain of seed for sprouting.

Between 1996 and 2020, there were 52 reported outbreaks of foodborne illness associated with contaminated sprouts, resulting in more than 2,700 cases of illness. Although contamination can occur at any point along the sprout supply chain, seed has historically been, and continues to be, identified as the likely source of contamination in many of these outbreaks. The Produce Safety Rule (PSR) includes sprout-specific requirements for sprout growers. However, we do not consider seed for sprouting to be covered produce under the PSR and, therefore, the growing, conditioning, and distribution of seed for sprouting is not subject to PSR requirements. Although seed used for sprouting is not covered by the PSR, the FDA does consider seed used for sprouting to be food.

The final guidance recommends that everyone in the sprout seed supply chain become as informed as reasonably possible about the food safety practices, processes, and procedures followed by the firm(s) from which they source their seed, where the seed will go after it leaves their firm, and whether their seed is reasonably likely to be used to produce sprouts for human consumption. The final guidance acknowledges that the practices and conditions appropriate for producing seed for sprouting likely will necessitate a higher level of food safety precautions compared to practices and conditions for producing seed that will be used for other purposes.

Consistent with the draft guidance published in June 2019, this final guidance recommends that seed for sprouting be grown using Good Agricultural Practices or in conformance with international standards such as the Codex Alimentarius International Code of Hygienic Practice for Fresh Fruits and VegetablesExternal Link Disclaimer. In addition, this guidance clarifies that testing should not be used in place of GAPs or Codex standards.

USA – Bring Food Safety to Your Summer Vacation

FSIS USDA

As summertime brings families and friends together for outdoor celebrations, the U.S. Department of Agriculture (USDA) wants to make sure your summer festivities are food safe. Whether you’re grilling burgers, camping, or having a picnic, everyone should always remember to practice proper handwashing and use a food thermometer.

After observing that consumer behavior in test kitchens revealed that people are skipping basic food safety practices, USDA is concerned that consumers are not doing enough to reduce the risk of foodborne illness.

“Our research shows that participants were not adequately washing their hands or using a food thermometer,” says USDA Deputy Under Secretary for Food Safety Sandra Eskin “Summer is a time to relax and enjoy delicious meals with friends and family but foodborne pathogens never rest. Following safe food handling practices during this and all other seasons can reduce the risk of you and your loved ones getting sick.”

USDA encourages all Americans to follow these food safety tips to keep you and your family foodborne illness free this summer.

Wash Your Hands

Inadequate handwashing is a contributing factor to many illnesses, including foodborne illness. It is important to follow proper handwashing steps before, during, and after preparing food to prevent bacteria from transferring from your hands to your meal.

Recent USDA consumer research (January 2020-2021) showed that 56% of participants didn’t attempt to wash their hands during meal preparation. This is a major drop in handwashing attempts from prior years’ research. In year 3, this figure was 71% and in year 2 it was 74%.

In addition to low attempts at handwashing, roughly 95% of participants failed to wash their hands properly. The most common reason in the study for unsuccessful handwashing was failing to rub hands with soap for at least 20 seconds, followed by not wetting hands with water as a first step.

There are five steps for proper handwashing: wet hands, lather with soap, scrub for 20 seconds, rinse, and dry.

Use a Food Thermometer

Don’t forget to bring a food thermometer to your summer activities. Always use a food thermometer to check the internal temperature of your food to determine if it is safe to eat. Insert the thermometer into the thickest part of the meat, through the side, for the most accurate temperature reading. In the study, only 55% of participants used a food thermometer to check the internal temperature of the hamburgers and sausages they were cooking. Use a food thermometer to ensure the following foods have reached their safe internal temperature:

  • Beef, pork, lamb and veal steaks, chops and roasts: 145 F with a 3-minute rest
  • Fish: 145 F
  • Egg dishes: 160 F
  • Ground meats (beef, pork, lamb and veal): 160 F
  • All poultry (whole or ground): 165 F

Avoid Cross-Contamination

While preparing your meal this Memorial Day, be sure to keep your raw meat separate from your fruits and vegetables. Raw meat and poultry can carry bacteria that causes foodborne illness. To reduce the risk of cross-contamination, USDA recommends using separate cutting boards: one for raw meat and poultry, and another for fruits and vegetables.

In this study, cross-contamination was prevalent. Across all participants:

  • 32% contaminated their plates and cutting boards while preparing food.
  • 28% contaminated their kitchen sinks.
  • 12% contaminated spice containers.
  • 8% contaminated the cupboard handles in their kitchen.

These findings are part of a multi-year, mixed-method study that USDA’s Food Safety and Inspection Service (FSIS) commissioned to evaluate various consumer food handling behaviors. The study uses test kitchens, focus groups, and nationally representative surveys to better understand food safety practices and experiences with food recalls, foodborne illness, and FSIS food safety resources. More information about this study is available in an executive summary.

USA – FDA Provides New Updates on Activities to Mitigate Infant Formula Supply Challenges, Abbott Nutrition Agrees to Take Corrective Actions at Facility to Produce Safe Infant Formula

FDA

The U.S. Food and Drug Administration is announcing important updates on its ongoing work to increase the supply and availability of infant formula in the U.S. On Feb. 17, the agency warned consumers not to use certain powdered infant formula products from Abbott Nutrition’s Sturgis, Michigan infant formula production facility, and Abbott voluntarily ceased production at this facility as well as initiated a voluntary recall of certain products.

Today, a proposed consent decree of permanent injunction between the FDA and Abbott Nutrition, as well as three Abbott principals, was filed in the U.S. District Court for the Western District of Michigan. Under the proposed consent decree, which is subject to court approval and entry, Abbott has agreed to take corrective actions following an FDA inspection of its Sturgis, Michigan facility. The proposed consent decree obliges Abbott to take actions that are expected to ultimately result in an increase of infant formula products, while ensuring that the company undertakes certain actions that would ensure safe powdered infant formula is produced at the facility. When the company decides to restart production at this facility, it must conform with the provisions of the proposed consent decree and meet FDA food safety standards. If contamination is identified, the company must notify the FDA, identify the source of the problem and conduct a root-cause investigation before resuming production.

“Today’s action means that Abbott Nutrition has agreed to address certain issues that the agency identified at their infant formula production facility in Michigan. The public should rest assured that the agency will do everything possible to continue ensuring that infant and other specialty formulas produced by the company meet the FDA’s safety and quality standards, which American consumers have come to expect and deserve,” said FDA Commissioner Robert M. Califf, M.D. “We recognize the hardships that parents and caregivers have faced in obtaining infant formula and the FDA is focused on boosting the availability of the country’s supply of these products, including new steps regarding importation. We are also taking a look at the supply of infant formulas developed by manufacturers across the country and around the world to determine if a reallocation of their distribution can be made to help get the right product to the right place, at the right time.” 

In the complaint, filed by the U.S. Department of Justice on behalf of the FDA, the government alleges that powdered infant formula products manufactured at Abbott Nutrition’s Sturgis facility were adulterated because they were made under insanitary conditions and in violation of current good manufacturing practice requirements. On Jan. 31, the FDA commenced a for-cause inspection and identified Cronobacter sakazakii, a bacterium that can potentially cause severe foodborne illness primarily in infants, in the facility and observed significant operational deficiencies. While the agency’s inspection was ongoing, Abbott Nutrition voluntarily recalled certain powdered infant formula products and voluntarily shut down its facility to implement corrective actions that address issues raised by the FDA.

Under the proposed consent decree, Abbott Nutrition will be required to retain an independent expert to review the Sturgis facility’s operations to ensure compliance with the law. It also includes requirements for testing products, as well as ceasing production, and promptly notifying the FDA should contamination be detected. The proposed consent decree also requires the implementation of a sanitation plan, environmental monitoring plan and employee training programs.

In the meantime, the FDA is also continuing to implement several important steps to improve the supply of infant and specialty formula products in the U.S. The agency has been in ongoing discussions with all infant formula manufacturers who are reporting that they are all producing at an expanded capacity. In fact, Gerber has reported that it increased the amount of their infant formula available to consumers by approximately 50% in March and April and Reckitt is supplying more than 30% more product year to date.

This increased production is now evident in increased infant formula sales. According to data from Information Resources Inc. (IRI), national infant formula sales by volume for the month of April were up more than 13% compared to the month prior to the recall and national infant formula sales by unit for the month of April are also up by more than 5% compared to the month prior to the recall.

While some data suppliers have reported lower in-stock rates, the most complete data sets available from IRI are showing nearly 80% in-stock rates at the week ending May 8. This means that if a local supermarket normally carries 50 different infant formula products, an 80% in-stock rate would translate to 40 of those 50 product types being available.

What the sales volume data and in-stock rates tell us is that while there is more product being sold, it may be of less variety than prior to the recall. With increased production by other manufacturers, forthcoming import actions and the potential for Abbott Nutrition’s Sturgis facility to resume production in the near-term, the FDA expects supply to continue to improve over the next couple of months. The FDA recognizes that there is variation in availability throughout the country and is working with federal partners to better understand where shortages of certain formulas exist at a more local level, as well as explore further ways to alleviate more immediate and geographical supply challenges through better distribution of products.

Increased sales are a good indicator of formula available to the general population of infants, but the agency understands that availability of specialty products such as amino acid-based specialty formulas and metabolic products continues to be of concern. The FDA has already taken steps with Abbott Nutrition to make product available to those with life-threatening conditions on a case-by-case basis and will continue its efforts to make these products even more readily available as the agency works with the company to implement provisions of the proposed consent decree. In addition, these products have been an area of focus for discussions with other manufacturers that make comparable products. As a result of the recall and work with the FDA, other manufacturers have increased production of comparable product lines and in some cases expedited the importation of these products where they exist.

The agency is also looking at ways to mitigate future, potential supply issues including building on work to date with its 21 Forward supply chain continuity system. It has made requests for new authorities from Congress to allow the FDA to regularly collect important supply data from the broader infant formula industry and is continuing to implement several important steps to improve supply.

The FDA is committed to transparently communicating updates on this dynamic situation. The agency will continue to dedicate all available resources to help ensure that infant formula products remain safe and available for use in the U.S. and will keep the public informed of progress updates.

Research – An Exploration of Listeria monocytogenes, Its Influence on the UK Food Industry and Future Public Health Strategies

MDPI

Listeria monocytogenes is a Gram-positive intracellular pathogen that can cause listeriosis, an invasive disease affecting pregnant women, neonates, the elderly, and immunocompromised individuals. Principally foodborne, the pathogen is transmitted typically through contaminated foods. As a result, food manufacturers exert considerable efforts to eliminate L. monocytogenes from foodstuffs and the environment through food processing and disinfection. However, L. monocytogenes demonstrates a range of environmental stress tolerances, resulting in persistent colonies that act as reservoirs for the reintroduction of L. monocytogenes to food contact surfaces and food. Novel technologies for the rapid detection of L. monocytogenes and disinfection of food manufacturing industries have been developed to overcome these obstacles to minimise the risk of outbreaks and sporadic cases of listeriosis. This review is aimed at exploring L. monocytogenes in the UK, providing a summary of outbreaks, current routine microbiological testing and the increasing awareness of biocide tolerances. Recommendations for future research in the UK are made, pertaining to expanding the understanding of L. monocytogenes dissemination in the UK food industry and the continuation of novel technological developments for disinfection of food and the food manufacturing environment View Full-Text

EU – Update: Multi-country Salmonella outbreak linked to chocolate products

EFSA

EFSA and ECDC have updated their assessment, published in April 2022, of the multi-country outbreak of monophasic Salmonella Typhimurium infections linked to chocolate products by a company in its Belgian plant.

Cases, which have now started to decrease, stood at 324 (including both probable and confirmed) in the EU/EEA and the UK, as of 18 May 2022. They have been reported in twelve EU/EEA countries (Austria, Belgium, Denmark, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Spain and Sweden), the UK, Switzerland, Canada, and USA. The first patient was reported in the UK on 7 January, with a sampling date of 21 December 2021.

On 8 April 2022, the food safety authority in Belgium stopped the production at the facility. Withdrawals and recalls have been implemented in the countries where chocolate products manufactured at the Belgian plant were distributed. Public warnings have been issued by the competent national authorities in different countries.

China – Outbreak Reports: Extensively Drug-Resistant (XDR) Salmonella Typhi Outbreak by Waterborne Infection — Beijing Municipality, China, January–February 2022

China CDC

kswfoodworld Salmonella

On February 6, 2022, an unusual infection event was noticed by hospitals and Beijing CDC: 4 clinically diagnosed typhoid cases (3 in Beijing, 1 in Chifeng City, Inner Mongolia Autonomous Region) were reported to China’s Infectious Disease Information System. The detailed epidemiological investigation was initiated by Changping District CDC. This outbreak involved 23 cases in an apartment in Changping District in Beijing and was caused by extensively drug-resistant (XDR) Salmonella Typhi (S. Typhi) through polluted water supply, which was confirmed by laboratory detection.

Based on the epidemiological curve by date of onset and spatial distribution of cases, a point outbreak was suggested. Considering the possibility of foodborne infection, we checked the dietary history of these cases for 14 days prior to onset, but no evidence of common food or dining together was found to support this. We did not conduct case-control studies, but we received information that most cases keep good hygiene in water usage: they did not drink raw water, but they used tap water to wash vegetables and brush teeth. During this survey, the residents reported that the household water had an odor for about half a month in late December 2021, and some reported that there was disruption of water supply and transient muddy water in mid-January 2022. Herein, the water supply in this apartment was further investigated. The domestic water was supplied from a self-provided well in the village, which was piped to six apartments including the apartment where the cases lived in. Water was pumped from a nearby branch well to storage tank on the roof of the apartment for 24 hours a day to ensure adequate water supply, and then distributed to each room. In field investigation, we learned that sewage pipeline reconstruction work was carried out in December 2021 near the apartment, and the sewage pipeline was just about 1 meter away from the branch well which supplied water for the apartment.

In summary, this was the first report of waterborne outbreak caused by XDR S. Typhi in China. Whole-genome comparison and drug resistance analysis indicated that it belonged to H58 lineage 4.3.1.1.P1 originating from Pakistan, which had the capacity to invade and spread globally by travel-associated international transmission, with the potential to replace native strains (4). However, it was unclear how this novel clone strain entered China and was associated with this outbreak, due to the lack of detailed historical epidemiological data. Importantly, in a modern city such as Beijing, especially in suburban or rural areas where the municipal water supply does not reach, there is still a potential risk of typhoid fever outbreak. So, it is urgent to appeal to relevant governmental authorities to provide safe and hygienic potable water, strengthen supervision on water quality, and educate the public to keep good hygiene habits. In addition, with narrow treatment options for typhoid fever, XDR typhoid itself should also attract great attention, which may lead to treatment failure, prolonged hospitalization, as well as recurrent and extensive transmission of the disease. Therefore, it is necessary to track the source of the XDR strains and to strengthen monitoring their spread through laboratory and extensive epidemiological investigations in the future.
