   <dc:description>A total of 1 105 samples of animal- and plant-derived products, including milk and milk products, eggs, meat&#xd;
and meat products, (herbal) teas and (herbal) food supplements were analysed for the presence of 28 or&#xd;
35 pyrrolizidine alkaloids (PAs). Samples were collected in supermarkets, retail shops and for a small proportion&#xd;
via internet between January 2014 and April 2015, in six European countries (France, Germany, Greece, Italy,&#xd;
the Netherlands and Spain). The samples comprised 268 milk and milk products (including yoghurt, cheese and&#xd;
infant formula), 205 eggs, 273 meat (including beef, pork and poultry meat, and liver of beef, pork and chicken),&#xd;
168 teas (including black, green, rooibos, chamomile, peppermint and mixed herbal tea) and 191 food&#xd;
supplements. All samples were analysed by liquid chromatography coupled to tandem mass spectrometry. The&#xd;
limit of quantification depended on the matrix (from ≤ 0.1 µg/L in milk to 5-10 µg/kg in oil-based food&#xd;
supplements) and was considered fit-for-purpose. One or more PAs were detected in 2 % of the animal-derived&#xd;
products, in 91 % of the (herbal) teas and in 60 % of the food supplements. Eleven milk samples (6 %) contained&#xd;
PAs, but the levels were relatively low (between 0.05 and 0.17 µg/L). Only two egg samples contained trace&#xd;
amounts of PAs (0.10-0.12 µg/kg), and no PAs were detected in the other animal-derived products. In contrast,&#xd;
all types of (herbal) teas investigated were found to contain PAs, with a mean concentration of 6.13 µg/L in&#xd;
(herbal) tea infusion (corresponding to 460 µg/kg dry tea). The highest mean concentrations were found in&#xd;
rooibos tea (7.99 µg/L tea infusion) and the lowest in chamomile (3.65 µg/L tea infusion). Occurrence of PAs in&#xd;
food supplements was found to be highly variable, with the highest concentrations present in supplements&#xd;
containing plant material from known PA-producing plants.</dc:description>
