Abstract Background The safety assessment of foods and feeds from genetically modified (GM) crops includes the comparison of key characteristics, such as crop composition, agronomic phenotype and observations from animal feeding studies compared to conventional counterpart varieties that have a history of safe consumption, often including a near isogenic variety. The comparative compositional analysis of GM crops has been based on targeted, validated, quantitative analytical methods for the key food and feed nutrients and antinutrients for each crop, as identified by Organization of Economic Co-operation and Development (OCED). As technologies for untargeted metabolomic methods have evolved, proposals have emerged for their use to complement or replace targeted compositional analytical methods in regulatory risk assessments of GM crops to increase the number of analyzed metabolites. Aim of Review The technical opportunities, challenges and strategies of including untargeted metabolomics analysis in the comparative safety assessment of GM crops are reviewed. The results from metabolomics studies of GM and conventional crops published over the last eight years provide context to enable the discussion of whether metabolomics can materially improve the risk assessment of food and feed from GM crops beyond that possible by the Codex-defined practices used worldwide for more than 25 years. Key Scientific Concepts of Review Published studies to date show that environmental and genetic factors affect plant metabolomics profiles. In contrast, the plant biotechnology process used to make GM crops has little, if any consequence, unless the inserted GM trait is intended to alter food or feed composition. The nutritional value and safety of food and feed from GM crops is well informed by the quantitative, validated compositional methods for list of key analytes defined by crop-specific OECD consensus documents. Untargeted metabolic profiling has yet to provide data that better informs the safety assessment of GM crops than the already rigorous Codex-defined quantitative comparative assessment. Furthermore, technical challenges limit the implementation of untargeted metabolomics for regulatory purposes: no single extraction method or analytical technique captures the complete plant metabolome; a large percentage of metabolites features are unknown, requiring additional research to understand if differences for such unknowns affect food/feed safety; and standardized methods are needed to provide reproducible data over time and laboratories.

Aldioxa is a heterocyclic organic compound used in cosmetic products as an astringent and skin conditioning agent. The oral LD50 for mice exceeds 23 mg/kg, and 8 g/kg for rats. All of the toxicologic parameters investigated in a 94-day subchronic feeding study in rats were similar in the test and the control group. No significant macroscopic adverse results were obtained in a three generation study in which rats were fed diets containing 10% Aldioxa. A suspension containing 25% Aldioxa was not a sensitizer when applied to the shaved backs of 3 male guinea pigs, nor when 10 animals were given intradermal injections of a 2% Aldioxa suspension on alternating days for a total of 10 applications and challenged after a 10-day nontreatment period. A hydrophilic unguent containing 4% Aldioxa was neither an irritant nor a sensitizer when evaluated on 200 human volunteers. The safety of Aldioxa has not been completely documented and substantiated. It cannot be concluded that this ingredient is safe for use in cosmetic products until the appropriate needed safety data cited in the report have been obtained and evaluated.

Abstract This paper evaluates the potential hazards of food and feed derived from RNAi plants including: adverse changes of plant metabolism; mechanisms and potential for non-target gene silencing in humans and livestock, including gut microbiome; bioinformatics tools for predictionof off-target sequences of interfering RNA; the possible non-specific effects of dsRNA and siRNA in mammals; and the comparison of data requirements for safety assessment of food and feed from RNAi plants and from plants expressing recombinant proteins. It also discusses exposure and RNAi-specific risk assessment.
