The European Commission asked EFSA for a scientific evaluation on the risks to human health related presence of perfluoroalkyl substances (PFASs) in food. Based several similar effects animals, toxicokinetics and observed concentrations blood, CONTAM Panel decided perform assessment sum four PFASs: PFOA, PFNA, PFHxS PFOS. These made up half lower bound (LB) exposure those PFASs with available occurrence data, remaining contribution being primarily from short half-lives. Equal potencies were...
The European Commission asked EFSA for a scientific evaluation on the risks to human health related presence of perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic (PFOA) in food. Regarding PFOS PFOA occurrence, final data set available dietary exposure assessment contained total 20,019 analytical results (PFOS n = 10,191 9,828). There were large differences between upper lower bound due methods with insufficient sensitivity. CONTAM Panel considered estimates be closer true levels....
Deoxynivalenol (DON) is a mycotoxin primarily produced by Fusarium fungi, occurring predominantly in cereal grains. Following the request of European Commission, CONTAM Panel assessed risk to animal and human health related DON, 3-acetyl-DON (3-Ac-DON), 15-acetyl-DON (15-Ac-DON) DON-3-glucoside food feed. A total 27,537, 13,892, 7,270 2,266 analytical data for 3-Ac-DON, 15-Ac-DON DON-3-glucoside, respectively, food, feed unprocessed grains collected from 2007 2014 were used. For exposure,...
Ever since the interest in organic environmental contaminants first emerged 50 years ago, there has been a need to present discussion of such chemicals and their transformation products using simple abbreviations so as avoid repetitive use long chemical names. As number concern increased, also increased dramatically, sometimes resulting different for same chemical. In this article, we propose flame retardants (FRs) substituted with bromine or chlorine atoms including functional group...
The European Commission asked EFSA for a scientific opinion on the risks animal and human health related to presence of dioxins (PCDD/Fs) DL-PCBs in feed food. data from experimental epidemiological studies were reviewed it was decided base risk assessment effects observed humans use as supportive evidence. critical effect semen quality, following pre- postnatal exposure. study showed NOAEL 7.0 pg WHO
In 2011, a joint World Health Organization (WHO) and United Nations Environment Programme (UNEP) expert consultation took place, during which the possible inclusion of brominated analogues dioxin-like compounds in WHO Toxicity Equivalency Factor (TEF) scheme was evaluated. The panel concluded that polybrominated dibenzo-p-dioxins (PBDDs), dibenzofurans (PBDFs), some biphenyls (dl-PBBs) may contribute significantly daily human background exposure to total dioxin toxic equivalencies (TEQs)....
Zearalenone (ZEN), a mycotoxin primarily produced by Fusarium fungi, occurs predominantly in cereal grains.The European Commission asked EFSA for scientific opinion on the risk to animal health related ZEN and its modified forms feed.Modified of occurring feed include phase I metabolites a-zearalenol (a-ZEL), b-zearalenol (b-ZEL), a-zearalanol (a-ZAL), b-zearalanol (b-ZAL), zearalanone (ZAN) II conjugates.ZEN has oestrogenic activity differs considerably.For ZEN, Panel Contaminants Food...

The European Commission asked EFSA to update its 2011 risk assessment on polybrominated diphenyl ethers (PBDEs) in food, focusing 10 congeners: BDE-28, -47, -49, -99, -100, -138, -153, -154, -183 and ‑209. CONTAM Panel concluded that the neurodevelopmental effects behaviour reproductive/developmental are critical rodent studies. For four congeners (BDE-47, -209) derived Reference Points, i.e. benchmark doses corresponding lower 95% confidence limits (BMDLs), for endpoint-specific responses....
Concentrations of 24 elements including metals in the 2006 UK Total Diet Study (TDS) were measured and dietary exposures estimated. Composite samples for 20 TDS food groups (bread, fish, fruit, etc.) collected from towns analysed their levels aluminium, antimony, arsenic, barium, bismuth, cadmium, chromium, copper, germanium, indium, lead, manganese, mercury, molybdenum, nickel, palladium, platinum, rhodium, ruthenium, selenium, strontium, thallium, tin, zinc. each lower than or similar to...
There is increasing concern over the toxicity and environmental distribution of a number classes brominated compounds such as polybrominated diphenyl ethers (PBDEs), biphenyls (PBBs) used flame retardants well mixed bromochloro dibenzo-p-dioxins dibenzofurans (PBDD/Fs PBrClDD/Fs). Observed ubiquity bio-accumulative characteristics coupled with dioxin-like have led to some these being classified POPs. Unlike chlorinated dioxins levels in environment shows an trend. The main pathway observed...
Tetrodotoxin (TTX) and its analogues are produced by marine bacteria have been detected in bivalves gastropods from European waters. The Commission asked EFSA for a scientific opinion on the risks to public health related presence of TTX gastropods. Panel Contaminants Food Chain reviewed available literature but did not find support minimum lethal dose humans 2 mg, mentioned various reviews. Some human case reports describe serious effects at 0.2 corresponding 4 μg/kg body weight (bw)....
The most commonly consumed shellfish species produced in Scotland - mussels, oysters and scallops were investigated for the occurrence of a range brominated chlorinated contaminants order to establish current levels estimate human dietary exposure. Flesh from individual sub-samples was representatively pooled 35 composites analysed dioxins (PBDD/Fs, PCDD/Fs), biphenyls (PBBs, PCBs), polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs) tetrabromobisphenol A (TBBPA)....

The EFSA Panel on Contaminants in the Food Chain (CONTAM) established a tolerable daily intake (TDI) for fumonisin B
Fumonisins, mycotoxins primarily produced by Fusarium verticillioides and proliferatum, occur predominantly in cereal grains, especially maize. The European Commission asked EFSA for a scientific opinion on the risk to animal health related fumonisins their modified hidden forms feed. Fumonisin B1 (FB 1), FB 2 3 are most common of feedstuffs thus were included assessment. 1, have same mode action considered as having similar toxicological profile potencies.
