The European Commission asked EFSA for a risk assessment on complex organoarsenic species in food. They are typically found in marine foods and comprise mainly arsenobetaine (AsB), arsenosugars and arsenolipids. For AsB, no reference point (RP) could be derived because of insufficient toxicity data.

Genetically modified strain MXY0541 was developed to produce soy leghemoglobin by introducing the coding sequence encoding leghemoglobin from soybean (). The molecular characterisation data and bioinformatic analyses do not raise any safety concerns. The safety of soy leghemoglobin as a food additive has already been assessed by the EFSA FAF Panel (EFSA-Q-2022-00031).

Genetically modified maize DP51291 was developed to confer control against susceptible corn rootworm pests and tolerance to glufosinate-containing herbicide; these properties were achieved by introducing the and expression cassettes. The molecular characterisation data and bioinformatic analyses do not identify issues requiring food/feed safety assessment. None of the identified differences in the agronomic/phenotypic and compositional characteristics tested between maize DP51291 and its conventional counterpart needs further assessment, except for phosphorus in forage and manganese, proline, oleic acid (C18:1) and linoleic acid (C18:2) in grain, which do not raise safety and nutritional concerns.

Article Synopsis
  • The European GMO Panel reviewed new information regarding a genetically modified soybean application (MON × MON 87708 × MON 89788) after a request from the European Commission.
  • A 90-day feeding study demonstrated that diets containing the GM soybean did not show any adverse effects in rats, meeting regulatory requirements.
  • The panel concluded that the GM soybean is as safe as its non-GM counterparts and does not present nutritional concerns for humans or animals based on the findings from both earlier assessments and the recent study.

Article Synopsis
  • The gut microbiome is crucial for our body's functioning, but the effects of non-nutritious food components on it are often ignored.
  • Certain food additives and microplastics may negatively impact the gut microbiome and human health, and understanding the mechanisms behind this is essential.
  • Recommendations include integrating gut microbiome research into food safety assessments to better evaluate the risks of food additives and contaminants.

The European Commission requested EFSA to provide an update of the 2012 Scientific Opinion of the Panel on Contaminants in the Food Chain (CONTAM) on the risks for animal health related to the presence of ergot alkaloids (EAs) in feed. EAs are produced by several fungi of the and genera. This Opinion focussed on the 14 EAs produced by (ergocristine, ergotamine, ergocornine, α- and β-ergocryptine, ergometrine, ergosine and their corresponding 'inine' epimers).

The European Commission asked EFSA to update its 2009 risk assessment on arsenic in food carrying out a hazard assessment of inorganic arsenic (iAs) and using the revised exposure assessment issued by EFSA in 2021. Epidemiological studies show that the chronic intake of iAs via diet and/or drinking water is associated with increased risk of several adverse outcomes including cancers of the skin, bladder and lung. The CONTAM Panel used the benchmark dose lower confidence limit based on a benchmark response (BMR) of 5% (relative increase of the background incidence after adjustment for confounders, BMDL) of 0.

Article Synopsis
  • - Genetically modified maize DP23211 was engineered to resist specific pests and tolerate a certain herbicide, with no critical safety issues found in molecular and bioinformatic analyses.
  • - Differences in nutrient levels were noted but did not pose safety or nutritional concerns, and the GMO Panel deemed the new proteins and RNA from the modification to be safe for consumption.
  • - Overall, maize DP23211 is considered just as safe for human and animal health as conventional maize, and no additional monitoring for safety or environmental impact is required.

In 2004, the EFSA Panel on Contaminants in the Food Chain (CONTAM) adopted a Scientific Opinion on the risks to animal health and transfer from feed to food of animal origin related to the presence of ochratoxin A (OTA) in feed. The European Commission requested EFSA to assess newly available scientific information and to update the 2004 Scientific Opinion. OTA is produced by several fungi of the genera and .

Mineral oil hydrocarbons (MOH) are composed of saturated hydrocarbons (MOSH) and aromatic hydrocarbons (MOAH). Due to the complexity of the MOH composition, their complete chemical characterisation is not possible. MOSH accumulation is observed in various tissues, with species-specific differences.

Genetically modified cotton COT102 was developed to confer resistance against several lepidopteran species. The molecular characterisation data and bioinformatic analyses do not identify issues requiring food/feed safety assessment. None of the differences in the agronomic-phenotypic and compositional characteristics between cotton COT102 and its non-GM comparator needs further assessment, except for levels of acid detergent fibre, which do not raise safety or nutritional concerns.

Genetically modified maize Bt11 × MIR162 × MIR604 × MON 89034 × 5307 × GA21 was developed by crossing to combine six single events: Bt11, MIR162, MIR604, MON 89034, 5307 and GA21, the GMO Panel previously assessed the 6 single maize events and 27 out of the 56 possible subcombinations and did not identify safety concerns. No new data on the single maize events or the assessed subcombinations were identified that could lead to modification of the original conclusions on their safety. The molecular characterisation, comparative analysis (agronomic, phenotypic and compositional characteristics) and the outcome of the toxicological, allergenicity and nutritional assessment indicate that the combination of the single maize events and of the newly expressed proteins in the six-event stack maize does not give rise to food and feed safety and nutritional concerns.

Article Synopsis
  • A genetically modified maize called MON 89034 × 1507 × MIR162 × NK603 × DAS-40278-9 was created by crossing five existing maize events, all of which have been previously assessed for safety.
  • The GMO Panel found no new safety concerns regarding these maize events or their combinations, indicating the new genetically modified maize poses no additional risks to food safety or health.
  • Furthermore, the panel concluded that the five-event maize stack and its combinations are as safe as traditional non-GM maize varieties, and potential accidental environmental releases would not create safety issues.
