    The Fifty-second Session of the Codex Committee on Food Hygiene (CCFH) requested the Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) to undertake full production-to-consumption risk assessments of L. monocytogenes in foods to inform a possible revision of the Guidelines on the application of general principles of food hygiene to the control of Listeria monocytogenes in foods.In response to this request, JEMRA convened a series of meetings, to prepare and develop risk assessments for Listeria monocytogenes in various foods. Several risk assessment models were developed and evaluated to characterize the risk of listeriosis due to the consumption of diced ready-to-eat cantaloupe, frozen vegetables, and cold-smoked ready-to-eat fish. Additionally, an updated dose–response model for Listeria monocytogenes was developed.This report describes the output of this expert meeting and the advice herein is useful for both risk assessors and risk managers, at national and international levels and those in the food industry working to control the hazard in foods.

    The International Network on Soil Pollution (INSOP) and the International Network on Soil Fertility and Fertilizers (INSOILFER) harmonize standard operating procedures (SOPs) for determining the analysis of fertilizers and make them available online – to all users for free. SOPs offer step-by-step instructions on how to perform laboratory analyses. SOPs are a critical component in ensuring the quality, safety and replicability of measurements and the credibility and traceability of data. The globally harmonized protocol for detecting heavy metals in fertilizers was developed with the assistance of 85 laboratories from 60 countries. Its aim is to facilitate the quality and safety analysis of heavy metals in fertilizers.
