Researchers tackle Salmonella in onions

Uvalde Leader News

Salmonella contamination of bulb onions, which caused recalls across the U.S. and Canada in 2020, is the focus of a Texas A&M AgriLife Research project to help onion producers solve the problem.

Salmonella outbreaks in onions and onion products show that the pathogen might persist during production, handling or storage. This is a significant concern to the onion produce industry, researchers said.

“Little is known about salmonella’s behavior related to bulb onions,” said Vijay Joshi, Ph.D., AgriLife Research assistant professor in the Department of Horticultural Sciences and systems physiologist at the Texas A&M AgriLife Research and Extension Center at Uvalde.

Joshi’s team, over the next two years, with more than $400,000 in grant support from the Center for Produce Safety, will develop an onion-specific risk reduction plan to deliver to industry.

Research – Factors Potentially Contributing to the Contamination of Packaged Leafy Greens Implicated in the Outbreak of Salmonella Typhimurium During the Summer of 2021

FDA

In July and August of 2021, the U.S. Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDC), and state partners conducted an outbreak investigation into a multistate outbreak of Salmonella Typhimurium linked to packaged leafy greens produced at a Controlled Environment Agriculture (CEA) indoor hydroponic operation.[1]

Total Illnesses: 31
Hospitalizations: 4
Deaths: 0
First illness onset: June 10, 2021
Last illness onset: August 18, 2021
States with Cases:  IL (18), MI (1), PA (2) WI (10)

The outbreak response investigation found:

  1. The outbreak was associated with the consumption of packaged leafy greens from the firm’s CEA indoor hydroponic operation; 26 of 27 (96%) patients reported consuming any leafy greens prior to illness onset, with 20 of 24 cases reporting consumption of prepackaged salads. This firm’s products were named specifically in 14 cases.
  2. This outbreak was caused by Salmonella Typhimurium as determined by whole genome sequencing (WGS) analysis. The Salmonella Typhimurium isolates from ill consumers were closely related genetically; however, there were no product isolates for comparison.
  3. Loyalty card data was received for nine cases. The information identified a common brand of packaged salads and the traceback investigation determined all of the points-of-service (POS) were supplied by the same hydroponic operation owned and operated by this firm. The firm’s salad products purchased by ill consumers were confirmed to be produced at the firm’s hydroponic operation.

FDA conducted an on-site produce safety investigation of the firm’s CEA operation, as part of the outbreak investigation.

Slovakia – Report on zoonoses, foodborne diseases and waterborne diseases in the Slovak Republic in 2020

MPSR

 

The protection of human and animal health can only be achieved through the active cooperation of experts in the field of control and research in the human and veterinary field. The report on zoonoses, foodborne diseases and waterborne diseases in the Slovak Republic for 2020 contains data from official inspections carried out in the field of agriculture and health care, as well as from research institutes and universities. The preparation of the report was coordinated by the National Contact Point for Scientific and Technical Cooperation with the European Food Safety Authority (EFSA EFSA), which is established at the Department of Food Safety and Nutrition of the Ministry of Agriculture and Rural Development of the Slovak Republic (MPRV SR).

The report serves as a basis for the EFSA NCB and scientific experts to set priorities and own national food safety risk assessments. At the same time, the report serves as one of the bases for the Community risk assessment carried out by the European Food Safety Authority (EFSA). Scientific risk assessment is the basis for risk management. The report describes the situation in  35 zoonotic agents, 5 foodborne diseases (ie foodborne diseases) without zoonotic potential and 4 waterborne pathogens. Of the 44 agents monitored, 23 are bacterial, 10 parasitic, 10 viral and prion.

It presents the summary results of examinations and tests performed in 2020 in the Slovak Republic and the evaluation of the national epidemiological situation in humans and animals with a focus on trends and sources of zoonotic and foodborne diseases.

The report presents the summary results of examinations and tests carried out in 2020 and an assessment of the national epidemiological situation in humans and animals , focusing on trends and sources of zoonotic and foodborne diseases . The number of monitored authors, cooperating organizations and experts is growing every year. A wide team of more than 70 experts from 24 scientific and control organizations in the Slovak Republic took part in its elaboration .

In 2020, 17,067 human diseases caused by the study agents were reported, with 29.1% related to campylobacteriosis, 20.9% to Clostridium dificille and 20.4% to salmonellosis. Rotavirus 11.6%, Norwalk virus 5.1%, Borrelia burgdorferi sl 5.6% and  Escherichia coli 1.2% also contributed to a higher percentage of diseases.

Seven of the study agents caused 380 human epidemics, of which 56.6% were salmonellosis, 23.2% were campylobacteriosis and 12.6% of epidemics were caused by rotavirus. Norwalk virus accounted for 5.5%, tick-borne encephalitis virus 1.3%, shigella and 0.5% and yersinia 0.3%.  

35,957 food samples were examined for the presence of 15 pathogens with a positive finding in 2.2% of samples. Higher percentages of positive findings were in  Yersinia spp. 48.1%, Enterococcus spp. 46.3% and  Vibrio spp. 31.8%.

The presence of 30 pathogens was monitored in 2,483,239 samples originating from livestock and wild animals, pets and zoos taken as part of official control, preventive monitoring, research, as well as from sick or dead animals. Positive findings accounted for 0.1% of samples. Higher percentages of positive findings were recorded for  Aeromonas spp. 59.3%, Clostridium spp. 55.4%, Francisella tularensis 50.4%, Babesia spp. 41.1%, Dirofilaria spp. 34.8%, Campylobacter spp. 18.3%, Yersinia spp. 18.3%, Staphylococcus aureus 18.1%, hepatitis E virus 14.1%, Listeria monocytogenes  11.8%, Toxocara spp. 10.5%.

Feed – 385 samples were examined for the presence of Salmonella spp. (1.5% positive samples), Escherichia coli (60.0% positive samples) and Clostridium spp.

(1.7% positive samples).

35,746 water samples were examined for the presence of 9 agents, of which 7.4% were positive, of which Legionella spp. 47.1% and Vibrio spp. 39.5%.

44,633 samples from the environment were examined for the presence of 8 pathogens, of which 2.3% were positive, of which Legionella spp. 36.0%, Vibrio spp. 6.8%,  E.coli 3.6% and  Enterococcus spp. 2.6%.

The report also includes the results of examinations for the resistance of microorganisms to antimicrobials, which has a growing trend worldwide and poses a real danger in the treatment of infections. Microbial resistance was monitored in Salmonella spp., E. coli , Campylobacter spp., Staphylococcus aureus and  Enterococcus spp.

The comprehensive report, which will be published as a publication, has a length of more than 130 pages, will be published in printed form, as a publication with an assigned ISBN. Summaries of individual chapters will be translated into English and published in an electronic version as a publication with an assigned ISBN.
