On the lookout for new strategies to test protein toxicity

The ANSES Fougères Laboratory coordinated the Protox project, which aimed to propose a strategy for determining protein toxicity using new approach methodologies (NAMs). Whether through food or our environment, we can be exposed to novel proteins whose health risks need to be assessed while minimising animal testing. Kevin Hogeveen, a toxicologist at the Fougères Laboratory and project coordinator, explains.

Laboratory for Hydrology: 200 years of safeguarding public health

ANSES's Nancy Laboratory for Hydrology celebrates its 200th anniversary this year. The safety of water is embedded in its DNA. Under the impact of climate change and new lifestyle patterns, this issue has become a major concern for society. Sophie Lardy-Fontan, its director, presents the laboratory.

Possible transmission of influenza D from cattle to pigs

Type D influenza is a flu virus that mainly affects cattle. However, ANSES's Ploufragan-Plouzané-Niort Laboratory recently isolated the virus in pigs for the first time in France. This crossing between species illustrates the importance of research aimed at improving the study of a possible risk of virus transmission to humans.

A metabolomic approach to assessing substance toxicity

The metabolic activity of cells could be used to determine the concentration above which a substance is toxic. A study conducted by ANSES scientists has explored this innovative approach, which could identify the concentration above which a substance poses a risk to human health based on in vitro test results.

Understanding the impact of pathogenic bacteria in the intestinal microbiota of pigs and chickens on human health

The presence of certain bacteria or chemicals can modulate the intestinal microbiota of pigs and chickens. Studying these factors could help at the farm level to tackle micro-organisms that are pathogenic to humans, such as Campylobacter and Salmonella .

How green peach aphids resist neonicotinoid insecticides

Neonicotinoids have long been used to combat aphids in crops Repeated use of these active substances has led to the selection of insects capable of resisting them. A study on the green peach aphid carried out by ANSES in collaboration with a research scientist from the University of Exeter (UK), revealed that resistance was based on two distinct mechanisms in this species. One is specific to the product's mode of action and the other is based on its degradation. The scientists' findings show that interactions between resistance mechanisms are possible, which is vital knowledge for adapting and adjusting control strategies.

Contaminant detection: a new score to assess the performance of testing laboratories

Scientists at ANSES have created a new score for statistically assessing the detection capabilities of testing laboratories. This score can be used when it is necessary to verify the ability of laboratories to detect a contaminant such as a pathogen or chemical in a sample.

Transmission of pathogens between pollinators

A study carried out in eight European countries confirms that pathogens can be transmitted from one species of pollinating insect to another. The health of wild pollinators can therefore be affected when a contaminated colony of honeybees is established nearby. Unlike in previous studies, the results did not show any significant effect of the type of crop grown in bee foraging areas.
