- This papercontainsbrief information on other actions takensubsequent tocompletion of recent COT discussions. This should be read in conjunction with the draft text of the Annual Report (paper TOX/2026/02), which provides the background.
COT ܲپDzԲ
2.During 2025, COT statements have been published onginger, mercury and citrinin in the maternal diet. These have been shared withScientific Advisory Committee on Nutrition(SACN)colleagues. The outcomesof earlier reviews have been incorporated into theirposition statementon the maternal diet whichis due to bepublishedlater this year.The nutrition and maternal weight outcomes report is the first of 2 publications on SACN’s assessment of nutrition and maternal health. This report considers SACN’s assessment of nutrition and maternal weight outcomes. A further position statement will consider wider UK dietary recommendations for women of childbearing age. This will include details of the COT statements describing COT’s assessments,findingsand associated advice.
3. A statement of advice on the risk to human health from consumption of bivalve molluscs (shellfish) harvested from UK waters associated with marine biotoxinswas also published.This has been provided to policy colleagues to support their work in this area.
4.COT opinions arefrequentlycited by the relevant Government Departments and Agencies in dealing with correspondence.
5.The Food Standards Agency (FSA)ԻUK Health Security Agency (UKHSA)routinely uses the Committee’s conclusions and opinions in risk assessments following food safety incidents,drinking water exceedances,responding to queries from consumersormembersof the publicand in assessing emerging risks. For instance,COTadvice was usedby the FSAinan incident involvinghigh levelsof bisphenol A(BPA)in piping tips for buttercream decoration. The tolerable daily intake(TDI)of0.2 µg BPA/kg bw/day set bythe German Federal Institute for Risk Assessment (BfR) and adopted by COT in2024 was usedtoconduct the risk assessment.
Other Committee activities
Regulated Products
6.TheCommittee has commented on number of AEJEG and FCM JEG opinions on various regulated products.
7.ճ FSA are now using the Scholastica publication tool for theto publish all FSA science reports.In2025,RP1702 (Calcium tert-butylphosphonateused as an additive for use in the manufacture of plastic food contact materials and articles)and RP1245 (Modification of Specifications ofRebaudiosideD (E960c) to Include Manufacture by Enzymatic Conversion)werepublished. Several applications are being held at the publication stage given applicant interest or completion of final comments, due to be published in March or in the first quarter of thenewfinancialyear; theseinclude RP507 (blue microalgae as a food additive),RP41(extension of use of curcumin), and 3 smoke flavouring assessments.
COTɴǰDZ
8.ճ COT held a workshop in October 2025in London, United Kingdom on“Exploring AI in Chemical Risk Assessment”.The workshop set out to explore the complex readiness of the data ecosystem andstate of the artAI technologies. Opportunities as well as challenges associated with application of AI in chemical safety assessment were reviewed and discussed.
9.TheɴǰDZreport will be publishedin due course.
10.Thereportof the 2024 COT workshop– Gut Reactions: xenobiotics and the microbiome was published.
Working GroupsԻSubgroups
Joint SACN-COT Working Group on plant-based drinks
11.ճ COT statementsfrom 2021fedinto the work of the joint COT–SACNWG onplant-baseddrinks. The WGundertooka BRAFO analysisofalmond, oat and soyadrinks compared tocows’milk.Thefinal report waspublished in2025with alargely positivereception.
12.The reportmade recommendations to government and industry.The Department of Health and Social Care is considering the recommendations made in the SACN/COT report carefully.Updated advice for consumerswill beprovided on NHS.uk
13.The government considered the report’s findings, alongside consultation responses and a range of evidence, to inform the decision to include plant-based and milk-substitute drinks in the Soft Drinks Industry Levy.
Cannabidiol (CBD)
14.Thejoint COT/Advisory Committee on Novel Foods and Processes(ACNFP)on cannabidiol (CBD) and hemp-based foodscontinues to support FSA activity onthese products.In 2025 they published a position paperon establishing a Safe Upper Limit for delta-9-tetrahydrocannabinol (Δ9-THC) and its precursor as contaminants of hemp-derived products including CBD novel foodalong witha statementon theconclusion of areview of aproposal under “REACH” by the French Agency(ANSES)to classify CBD through all exposure routes.This work continues to support the FSAin its approach to these products.
BTS and publications
15. Posters presenting the COT’s work onginger in the maternal dietand marine biotoxinswere presented at the BTS Annual Congress in April 2025.Posters onOcean-BoundPlastic and ashwagandhawere presentedat the 2025 AnnualEurotox congress
ʳܲپDzԲ
16.The report by RSM UK Consulting LLP on the Safety of Nitrates and Nitrites as Food Additiveswas published in Autumn 2025; COT Members provided peer review and general comments on the report. While therewassomecriticism fromcampaignersconcerned about nitrate use, the report forms part of the package of evidenceused by the FSAto informits position on nitrates.
17.ճ COT held a workshop“Gut reactions: xenobiotics and the microbiome” in October 2024.
18. The workshop set out to explore the complex current state of the science of the microbiome pathophysiology and the possible impact of xenobiotics on host microbiome interactions and vice versa, includingpossible mechanismsand health implications, with a particular emphasis on the gut microbiome and dietary exposure.
19. In addition, the aim was to enable new insights, review the science,initiatediscussions todeterminewhere the data gaps are in research, what effects are of concern, and how might xenobiotics be evaluatedpractically forsuch effects in the future.
20. The workshop report is now availableԻ.
