Research – Prevalence and antimicrobial resistance of foodborne pathogens in select fresh produce procured from farmers’ markets in Central Virginia

Wiley Online

As farmers’ markets have increased in size, scope, and complexity, so have potential food‐safety challenges and implications. Most products sold at farmers’ markets may receive minimal to no treatment of decontamination which could increase their potential microbial risks. The aim of this study was to assess the prevalence and antimicrobial resistance (AMR) of foodborne pathogens in select fresh produce procured from farmers’ markets in Central Virginia. A total of 138 samples produced by 15 farms and sold at 9 registered farmers’ markets were obtained between March and November 2017. CampylobacterEscherichia coli, and Listeria were, respectively, detected in 8.7, 9.4, and 8.0% of the samples. A total of 46 bacterial isolates consisted of CampylobacterE. coli, and Listeria were tested for their susceptibility to 12 antimicrobials. Ampicillin resistance showed the highest frequency among Campylobacter (100%) and E. coli (47.8%) isolates while nalidixic acid resistance was the highest in Listeria isolates (72.7%). At least 17% of each CampylobacterE. coli, and Listeria isolates exhibited multidrug resistance (MDR). No isolates had matching pulsed‐field gel electrophoresis (PFGE) profiles demonstrating that the E. coli isolates had a high degree of genomic diversity. This study demonstrated a potential health hazard arising from farmers’ market‐acquired fresh produce and emphasizes the importance of good agricultural and handling practices to prevent foodborne illness and spread of multidrug antibiotic resistance. Continued research is needed to determine and intervene the cause(s) of the observed prevalence and to support the healthy development of food products sold at farmers’ markets.

Norovirus Food Safety kswfoodworld

An investigation is underway after some residents, including children in a kindergarten in Ji’nan, East China’s Shandong Province, contracted the norovirus, according to the local authorities.

On March 11, some members of a residential community in Ji’nan, including some children from a kindergarten, were reported to be suffering syndromes of vomiting and diarrhea. District disease control and prevention personnel had taken samples of water, vomitus and related food for immediate further investigation.

Three children were sent to the hospital, but no severe cases were reported, and norovirus was detected in their vomit, the local authorities said on March 12.

The district education authority has temporarily closed the kindergarten and carried out a disinfection of its premises, and also taught children and parents on how to prevent norovirus infection.

Research – Behavioral Ethics and the Incidence of Foodborne Illness Outbreaks

Springer

Cognitive biases play an important role in creating and perpetuating problems that lead to foodborne illness outbreaks. By using insights from behavioural ethics, we argue that sometimes people engage in unethical behaviour that increases the likelihood of foodborne illness outbreaks without necessarily intending to or being consciously aware of it. We demonstrate these insights in an analysis of the 2011 Listeriosis outbreak in the U.S. from the consumption of contaminated cantaloupes. We then provide policy implications that can improve our understanding of other kinds of disease outbreaks and epidemics.

Outbreaks of norovirus in Sweden linked to shrimp from Estonia may have affected about 100 people.

Reports from local authorities have not been fully compiled yet but based on preliminary information officials believe more than 100 people have fallen sick.

It is mostly local outbreaks at workplaces where people have eaten shrimp sandwiches or a popular product in Scandinavia called “smörgåstårta.” This food, also called a sandwich cake, looks like a cake but instead of sponge uses bread and often includes cheese, vegetables, cold meats and fish.

Peeled shrimps in brine from the implicated batch were mostly distributed within one region which was named by local media as Varnamo in Jönköping County in southern Sweden.

Nigeria – Study Shows 76% Of Germs On Ready-To-Eat Fruits Are Multidrug-Resistant

Tribune Online

CONSUMPTION of fresh cut, ready-to-eat fruits (FCFs) processed and vended in open markets in Nigeria may constitute human health risks, causing food-borne diseases, due to microbial contamination, a study warns.

In the study, researchers had assessed pineapple and watermelon, which are among the commonest ready-to-eat fruits retailed and consumed regularly, including samples of fruit wash water and vendors’ hand, and found them heavily infested with different germs.

India – Evolution of Organic Food Safety Standards in India

FNB News

Food safety is the key to achieve better public health. The high incidence of foodborne illness is a burden on public health and contributes significantly to the cost of health care. Though most of the foodborne illnesses are rare and often not reported in India, however, a nationwide study reported an alarming 13.2 per cent prevalence at the household level. Therefore there is a need for a comprehensive approach for safer and nutritious food for Indian citizens. Safer food promises a healthier lifestyle, longer lives, less costly healthcare and more resilient food industry.
The Indian food industry is regulated by the number of legislations covering licensing, sanitation, and permits. Food Safety and Standards Act 2006, established by the Government of India, was a vital step in the direction of developing the standards for food and regulating and monitoring the manufacture, processing, storage, distribution, sale, and import of food to ensure the availability of safe and nutritious food for human consumption.

USA – Outbreak Investigation of Listeria monocytogenes – Hispanic-style Fresh and Soft Cheeses (February 2021) – Update

FDA

The FDA, along with CDC and state and local partners, are investigating a multistate outbreak of Listeria monocytogenes infections linked to queso fresco cheeses made by El Abuelito Cheese, Inc.

On 2/19/2021, El Abuelito Cheese, Inc. announced their initial recall of products, and on 2/27/2021, they announced the expansion of their recall to cover additional products that are manufactured or handled in the same facility as the Queso Fresco products linked to this outbreak.

On 3/9/2021, the FDA received confirmation that recalled cheeses were also distributed to Rhode Island. States with confirmed distribution now include: AL, CT, FL, GA, IA, IL, IN, KS, KY, MA, MD, MI, MN, MO, MS, NC, NJ, NY, NE, OH, PA, RI, SC, TN, VA, and WI. View additional recall information.

Recommendation

Consumers, restaurants, and retailers should not eat, sell, or serve any recalled Queso Fresco, Quesillo (Oaxaca, string cheese), or Requeson (ricotta) cheeses.

Recalled brands by cheese type include:

  • Queso Fresco: El Abuelito, Rio Grande, Rio Lindo
  • Quesillo: El Abuelito, El Viejito, El Paisano, El Sabrosito, La Cima, Quesos Finos, San Carlos, Ideal Brands
  • Requeson: El Abuelito, El Viejito

FDA recommends that anyone who purchased or received any recalled Queso Fresco, Quesillo, or Requeson cheeses use extra vigilance in cleaning and sanitizing any surfaces and containers that may have come in contact with these products to reduce the risk of cross-contamination. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces.

Some of the recalled cheeses were sold in bulk quantities and could have been repackaged by retailers. Ask your retailer if any Queso Fresco or Quesillo cheese you buy was repackaged from the cheeses recalled by El Abuelito. If you are unable to obtain an answer, do not buy it and throw away the potentially recalled cheese you have at home.

If you are at higher risk for severe Listeria infection (if you are pregnant, aged 65 or older, or have a weakened immune system due to certain medical conditions or treatments), call your healthcare provider right away if you have these symptoms after eating any Queso Fresco, Quesillo, or Requeson cheeses produced by El Abuelito:

  • Pregnant people typically experience only fever, fatigue, and muscle aches. However, Listeria infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
  • People who are not pregnant may experience headache, stiff neck, confusion, loss of balance, and convulsions, in addition to fever and muscle aches.

Follow these five steps to clean your refrigerator, containers, and surfaces that may have touched the cheeses. Listeria can survive in the refrigerator and can easily spread to other foods and surfaces.

Norway – Norway reports Salmonella outbreak, 10 people hospitalised

Outbreak News Today

The Norwegian Institute of Public Health (NIPH) is reporting a Salmonella outbreak which is geographically spread over large parts of country.

Twenty cases have been reported–12 confirmed and 8 suspected cases. The same genetic profile have been detected in all 12 confirmed cases. Preliminary analyzes of samples from the 8 suspected cases indicate that these also carry the outbreak strain.

Those affected are aged from 11 to 91 years, median age is 59 years. 60% are women. The infected live in Viken (9), Oslo (3), Innlandet (2), Vestfold and Telemark (1), Agder (1), Rogaland (1), Vestland (1), Møre og Romsdal (1) and Nordland (1). 10 of the cases have been hospitalized.

“The infected live in many different counties. Therefore, we believe that they are infected through a food that is widely distributed”, says doctor Hilde Marie Lund at the department of infection control and emergency preparedness.

Research – Prevalence of Listeria species on food contact surfaces in Washington State apple packinghouses

PubMed

The 2014 caramel apple listeriosis outbreak was traced back to cross-contamination between food contact surfaces (FCS) of equipment used for packing and fresh apples. For Washington State, the leading apple producer in the U.S with 79% of its total production directed to the fresh market, managing the risk of apple contamination with Listeria monocytogenes within the packing environment is crucial. The objectives of this study were to determine the prevalence of Listeria spp. on FCS in Washington State apple packinghouses over two packing seasons, and to identify those FCS types with the greatest likelihood to harbor Listeria spp. Five commercial apple packinghouses were visited quarterly over two consecutive year-long packing seasons. A range of 27 to 50 FCS were swabbed at each facility to detect Listeria spp. at two timings of sampling, (i) post-sanitation and (ii) in-process (three hours of packinghouse operation), following a modified protocol of the FDA’s Bacteriological Analytical Manual method. Among 2,988 samples tested, 4.6% (n=136) were positive for Listeria spp. Wax coating was the unit operation from which Listeria spp. were most frequently isolated. The FCS that showed the greatest prevalence of Listeria spp. were polishing brushes, stainless steel dividers and brushes under fans/blowers, and dryer rollers. The prevalence of Listeria spp. on FCS increased throughout apple storage time. The results of this study will aid apple packers in controlling for contamination and harborage of L. monocytogenes and improving cleaning and sanitation practices of the most Listeria-prevalent FCS.IMPORTANCE Since 2014, fresh apples have been linked to outbreaks and recalls associated with post-harvest cross-contamination with the foodborne pathogen L. monocytogenes These situations drive both public health burden and economic loss and underscore the need for continued scrutiny of packinghouse management to eliminate potential Listeria spp. niches. This research assesses the prevalence of Listeria spp. on FCS in apple packinghouses and identifies those FCS most likely to harbor Listeria spp. Such findings are essential for the apple packing industry striving to further understand and exhaustively mitigate the risk of contamination with L. monocytogenes to prevent future listeriosis outbreaks and recalls.
