Research – Intensive farming increases risk of epidemics

Science Daily

Overuse of antibiotics, high animal numbers and low genetic diversity caused by intensive farming techniques increase the likelihood of pathogens becoming a major public health risk, according to new research led by UK scientists.

An international team of researchers led by the Universities of Bath and Sheffield, investigated the evolution of Campylobacter jejuni, a bacterium carried by cattle which is the leading cause of gastroenteritis in high income countries.

Campylobacter facts:

  • Causes bloody diarrhea in humans
  • Transferred to humans from eating contaminated meat and poultry
  • Although not as dangerous as typhoid, cholera or E.coli, it causes serious illness in patients with underlying health issues and can cause lasting damage.
  • Around 1 in 7 people suffer from an infection at some point in their life
  • Causes three times more cases than E.coli, Salmonella and listeria combined
  • Carried in the faeces of chickens, pigs, cattle and wild animals
  • Campylobacter is estimated to be present in the faeces of 20% cattle worldwide
  • The bug is very resistant to antibiotics due to their use in farming

The researchers, publishing in the journal Proceedings of the National Academy of Sciences, studied the genetic evolution of the pathogen and found that cattle-specific strains of the bacterium emerged at the same time as a dramatic rise in cattle numbers in the 20th Century.

The authors of the study suggest that changes in cattle diet, anatomy and physiology triggered gene transfer between general and cattle-specific strains with significant gene gain and loss. This helped the bacterium to cross the species barrier and infect humans, triggering a major public health problem.

Combine this with the increased movement of animals globally, intensive farming practices have provided the perfect environment in which to spread globally through trade networks.

Professor Sam Sheppard from the Milner Centre for Evolution at the University of Bath, said: “There are an estimated 1.5 billion cattle on Earth, each producing around 30 kg of manure each day; if roughly 20 per cent of these are carrying Campylobacter, that amounts to a huge potential public health risk.

“Over the past few decades, there have been several viruses and pathogenic bacteria that have switched species from wild animals to humans: HIV started in monkeys; H5N1 came from birds; now Covid-19 is suspected to have come from bats.

“Our work shows that environmental change and increased contact with farm animals has caused bacterial infections to cross over to humans too.

“I think this is a wake-up call to be more responsible about farming methods, so we can reduce the risk of outbreaks of problematic pathogens in the future.”

Professor Dave Kelly from the Department of Molecular Biology and Biotechnology at the University of Sheffield said: “Human pathogens carried in animals are an increasing threat and our findings highlight how their adaptability can allow them to switch hosts and exploit intensive farming practices.”

The researchers hope that their study can help scientists predict potential problems in the future so they can be prevented before they turn into another epidemic.

Sweden – Histamine poisoning in Sweden linked to tuna from Vietnam

Food Safety News

Thirty people in Sweden fell ill with scombroid poisoning after eating tuna from Vietnam earlier this month.

The histamine poisoning foodborne outbreak was linked to frozen tuna loins from Vietnam, via the Netherlands.

Local authorities were responsible for the outbreak investigation and tracing of food batches. The Swedish Food Agency (Livsmedelsverket) is the national contact point for Europe’s Rapid Alert System for Food and Feed (RASFF).

Mats Lindblad, from the Swedish Food Agency, said about 30 people were sick but no deaths were reported.

“Symptoms were typical for histamine poisoning and included swelling, hives, irregular heartbeat, nausea, diarrhea and vomiting,” he told Food Safety News.

Switzerland – Officials report more patients in Listeria outbreak linked to cheese

At least 11 people in Switzerland have been infected by Listeria and two have died after eating contaminated cheese.

Officials from the Federal Food Safety and Veterinary Office (FSVO) told Food Safety News that analysis is pending for a further 10 infections to see if they belong to the outbreak cluster. A total of 28 cases of listeriosis have been reported in the country since early this year.

Of the 11 confirmed outbreak cases, five are men and six are women aged 66 to 86 years old. Infections have occurred in seven cantons, or regions, of the country.

The first patient related to the outbreak cluster showed symptoms at the end of January. In the most recent related infection reported to date, symptoms began in mid-April.

Research – Examination of the Culturable Microbiota from Low-Moisture Foods Imported into Canada for Antibacterial Activity against Listeria monocytogenes

Journal of Food Protection

ABSTRACT

Listeria monocytogenes, a resilient and ubiquitous foodborne pathogen, is associated with a high case-fatality rate in humans. This study investigated the culturable microbiota of low-moisture foods (LMFs) imported into Canada to see how well bacteria isolated from these foods could inhibit or inactivate the growth of L. monocytogenes. Imported LMFs were acquired from various supermarkets in the Greater Toronto Area (Ontario, Canada). The foods included dried apples, bee pollen, cumin seeds, date fruits, fennel seeds, pistachios, raisins, and seaweed. Bacterial strains were isolated from the foods using blood agar and then screened using an in-house-designed growth inhibition plate assay against L. monocytogenes. The inhibitory strains detected were then identified using 16S rRNA sequencing. Diverse bacteria were recovered from the foods; 236 isolates belonging to 122 observed phenotypes were obtained. From the inhibition plate assays, 10 of the 11 imported LMFs harbored inhibitory strains against L. monocytogenes, whereby 48 of the collected isolates (20%) were found to produce a zone of inhibition against this pathogen. The inhibitory strains belonged to six genera (Acinetobacter, Aerococcus, Bacillus, Lysinibacillus, Paenibacillus, and Sporosarcina) and 15 unique species. Among all foods tested, the date fruit microbiota displayed the greatest number and diversity of anti–L. monocytogenes inhibitory strains. Overall, it was found that the culturable microbiota of LMFs, imported into Canada, possess bacterial members that can inhibit the growth of L. monocytogenes. These results could lead to the discovery of either novel antimicrobial metabolites or beneficial anti–L. monocytogenes bacteria that could be added to foods to inactivate and/or control L. monocytogenes.

HIGHLIGHTS
  • Modification to an inhibition plate assay detects anti-Listeria bacteria more rapidly.
  • Unconventional anti-Listeria genera, such as Lysinibacillus, were discovered.
  • Date fruit microbiota warrants further investigation for anti-Listeria applications.
  • Isolated bacteria from low-moisture foods are diverse and can inhibit L. monocytogenes growth.
