host plant
Description:
A plant on which a pest lives or by which it is nourished
Context:
In food safety, a host plant is a plant that can support the growth, survival, or reproduction of a pathogen, pest, or contaminant. Identifying host plants is important because they can serve as a source or reservoir for harmful microorganisms, insects, or toxins that may later affect food crops or enter the food chain.
EFSA assesses risks to plant health linked to various pests (like Xylella fastidiosa for example), creates databases of susceptible plants, and advises EU policymakers on measures to prevent pest spread, protecting the food chain from devastating pathogens that may severely affect food production and crops.
