L. sativae has been repeatedly intercepted in the EU, especially in basil (Ocimum spp.). Climatic conditions and the wide availability of host plants provide conditions to support establishment in the EU, both in open fields and greenhouses. Impacts on field vegetables and ornamentals as well as hosts in greenhouses would be possible. Phytosanitary measures are available to reduce the likelihood of entry. L. sativae satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. Although human-assisted movement of vegetables is considered the main spread way for L. sativae, this agromyzid does not meet the criterion of occurring in the EU for it to be regarded as a potential Union regulated non-quarantine pest.The EFSA Panel on Plant Health performed a pest categorisation of Nemorimyza maculosa (Malloch) (Diptera Agromyzidae) for the European Union (EU). N. maculosa is an oligophagous pest; cultivated hosts include Chrysanthemum, lettuce and other Asteraceae although there is little evidence of recent impacts. N. maculosa occurs widely in the Americas and is present on the island of Madeira (Portugal), where it is under official control. N. maculosa is not known to occur in mainland Portugal based on surveys. N. maculosa can have multiple overlapping generations per year. Eggs are inserted into the leaves of host plants. Developing larvae feed within leaves causing blotch mines. Pupation takes place in the soil or under debris on the ground. Immature stages on leafy host plant material such as Chrysanthemum cut flowers provide potential pathways for entry into the EU. Human-assisted movement of cut flowers, fresh leafy hosts for consumption and plants for planting with foliage are considered the main pathways for entry. Climatic conditions and the wide availability of cultivated and wild host plants provide conditions to support establishment in the EU in the open and in greenhouse. The extent of potential impacts on hosts such as ornamental Asteraceae and lettuce in the EU is uncertain. N. maculosa is regulated in the EU by Commission Implementing Regulation 2019/2072 (Annex IIA) where it appears using a synonym, Amauromyza maculosa. Within the Regulation, the import of soil or growing medium, from third countries other than Switzerland is regulated and therefore prevents the entry of N. maculosa pupae. All criteria assessed by EFSA above for consideration either as a potential union quarantine pest or as a potential regulated non-quarantine pest were met.The Panel on Food Additives and Flavourings (FAF) provided a scientific opinion re-evaluating the safety of stearyl tartrate (E 483) as a food additive. The previously evaluated toxicological studies were not available, in addition to no genotoxicity data being available. Thus, adequate toxicity data on stearyl tartrate were not available for its re-evaluation. In addition, adequate data demonstrating the complete hydrolysis of stearyl tartrate (E 483) in the gastrointestinal tract and/or presystemically, that could allow read-across from data on its constituents, were lacking. Therefore, the safety of the use of stearyl tartrate as a food additive could not be assessed and the acceptable intake established by the Scientific Committee on Food (SCF) in 1978 could not be confirmed. Exposure to stearyl tartrate (E 483) was calculated using the maximum level exposure assessment scenario as neither use levels nor analytical data were available. Mean exposure to stearyl tartrate (E 483) as a food additive ranged from 0.1 mg/kg body weight (bw) per day in infants to 82.5 mg/kg bw per day in toddlers. The 95th percentile of exposure ranged from 0 mg/kg bw per day in adults to 192.7 mg/kg bw per day in toddlers. The Panel also noted that information from the Mintel's GNPD indicates that only two products have been labelled with stearyl tartrate (E 483) since 1996. Some recommendations were proposed by the Panel.The Panel on Food Additives and Flavourings (FAF) provided a scientific opinion re-evaluating the safety of acetic acid, lactic acid, citric acid, tartaric acid, mono- and diacetyltartaric acids, mixed acetic and tartaric acid esters of mono- and diglycerides of fatty acids (E 472a-f) as food additives. All substances had been previously evaluated by the Scientific Committee for Food (SCF) and by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). Hydrolysis of E472a,b,c,e was demonstrated in various experimental systems, although the available data on absorption, distribution, metabolism, excretion (ADME) were limited. The Panel assumed that E472a-f are extensively hydrolysed in the GI tract and/or (pre-)systemically after absorption into their individual hydrolysis products which are all normal dietary constituents and are metabolised or excreted intact. No adverse effects relevant for humans have been identified from the toxicological database available for E472a-f. The Panel considered that there is no need for a numerical acceptable daily intake (ADI) for E 472a,b,c. The Panel also considered that only l(+)-tartaric acid has to be used in the manufacturing process of E472d,e,f. The Panel established ADIs for E 472d,e,f based on the group ADI of 240 mg/kg body weight (bw) per day, expressed as tartaric acid, for l(+)-tartaric acid-tartrates (E334-337, 354) and considering the total amount of l(+)-tartaric acid in each food additive. Exposure estimates were calculated for all food additives individually, except for E 472e and f, using maximum level, refined exposure and food supplements consumers only scenarios. Considering the exposure estimates, there is no safety concern at their reported uses and use levels. In addition, exposure to tartaric acid released from the use of E 472d,e,f was calculated. The Panel also proposed a number of recommendations.The Panel on Food Additives and Flavourings (FAF) provided a scientific opinion re-evaluating the safety of metatartaric acid (E 353) when used as a food additive.  https://www.selleckchem.com/products/apx2009.html  Metatartaric acid (E 353) had been previously evaluated by the Scientific Committee on Food (SCF) and Joint FAO/WHO Expert Committee on Food Additives (JECFA). Based on the presumption that metatartaric acid is fully hydrolysed pre-systemically to l(+)-tartaric acid, the Panel concluded that metatartaric acid (E 353) should be included in the group acceptable daily intake (ADI) of 240 mg/kg body weight (bw) per day, expressed as tartaric acid, for l(+)-tartaric acid-tartrates (E 334-337, 354) which was established by the EFSA FAF Panel in 2020. Exposure estimates were calculated for metatartaric acid (E 353) using a maximum level and refined exposure assessment scenario. The Panel also concluded that there is no safety concern for the use of metatartaric acid (E 353) at the reported use and use level. The Panel made a number of recommendations.
