Food security
Millions of people are undernourished globally and with the population growing, food security is a major concern. Food security is multifaceted, requiring advancements in food safety, ensuring products have a good shelf life, reducing spoilage and providing dietary additions to improve the nutrient intake of the population. The application of microbiology is far reaching, and new approaches are required to maintain food security. Through an improved understanding of plant-microbe interactions, it is possible to forecast and mitigate food shortages.

The Nexus of Food Systems, Ecosystems and Human Health: Sign up for our fascinating free webinar!
What if health is not produced by humans alone, but co-created with the ecosystems, organisms, and food systems we depend on? A fascinating free webinar will explore how microbes connect people to food systems and the ecosystems that undergird food production.

NewsDNA analyses uncover what is hiding under the cap plaguing the white button mushroom industry
Researchers have uncovered that bacterial blotch is not caused by a single disease-causing bacteria or pathogen as originally learned, but by a complex of pathogenic bacterial species that thrive in the indoor controlled, humid environments where they are grown.

We caught up with Verônica Ortiz Alvarenga, a food engineer and Professor at Universidade Federal de Minas Gerais in Brazil, who is one of the newest Junior Editors with Letters in Applied Microbiology.
NewsDairy farms in California may transmit H5N1 virus through multiple sources
A new study suggests that avian influenza (H5N1) is transmitted through multiple, previously unknown sources on dairy farms and that some H5N1 positive cows do not show clinical signs of infection.

New research finds that almost all plant-based meat alternatives contain mycotoxins
New research into plant-based food and drinks has found a prevalence of mycotoxins – naturally occurring poisonous compounds produced by fungi - in hundreds of vegetarian and vegan products.
NewsModerate UV light is best to boost the vitamin D content of edible mushrooms, study finds
Researchers have discovered that moderate ultraviolet (UV) light exposure is best when the technique is used to enhance vitamin D₂ in edible mushrooms. Excessive exposure leads to nutrient degradation or a plateau effect, they found.
NewsNovel wheat hybrids increase resistance to major fungal disease by up to 70%
A new experimental study has identified a novel genetic locus in a common agricultural weed that provides significant resistance to Fusarium Head Blight (FHB) and has now been successfully transferred into wheat to produce FHB resistant hybrids.
NewsWhy antibiotics may soon fail to curb the plague bacterium - and where we can find new strategies
A new review shows that while most infections caused by the Yersinia plague bacterium can currently be treated with antibiotics, concerns about rising antimicrobial resistance mean that we need to come up with new ways to disarm the bacteria instead of killing them.
NewsSouth American camelids: Potential carriers of the zoonotic pathogen Campylobacter
A comprehensive investigation has identified a previously underappreciated source of thermotolerant Campylobacter spp. in South American camelids (SACs)—alpacas and llamas kept in Germany. The findings underscore the importance of expanding epidemiological surveillance beyond traditional livestock.
NewsHow does oligochitosan induce plant resistance against potato virus Y?
Plant immune inducers are crucial tools for the green management of crop diseases. As an environmentally friendly biological inducer, oligochitosan (COS) can activate plant defense mechanisms to resist pathogens such as fungi, bacteria, and viruses.
NewsCan rhizobacterial metabolites enhance plant drought tolerance?
A study shows that lettuce plants inoculated with PGPR strains exhibited significantly higher survival rates and better fresh weight recovery after drought stress compared to the uninoculated control group.
NewsTracking a persistent threat: How antibiotic-resistant bacteria travel from poultry farms to fresh produce
A new study develops an integrated quantitative microbial risk assessment (QMRA) model to trace the pathway of ESBL-producing E. coli from broiler farms to lettuce consumption, quantifying human health risks and identifying effective intervention strategies.
NewsHow bacteria circumvent plants’ immune system
In order to defend themselves, plants have to quickly produce proteins that detect and combat infiltrating microbes. Researchers discovered that Pseudomonas syringae disrupts this process by triggering the formation of P-bodies – small, droplet-like structures in the cell that store and regulate RNA molecules.
