This document describes a procedure for the determination of aflatoxins B1, B2, G1 and G2 and total aflatoxins (sum of B1, B2, G1 and G2) in spices for which EU maximum levels are established, other than paprika, by high performance liquid chromatography (HPLC) with post-column derivatization (PCD) and fluorescence detection (FLD) after immunoaffinity column clean-up.

The method is applicable to the spices capsicum, pepper, nutmeg, ginger, turmeric and mixtures thereof.

The method has been validated for aflatoxins B1, B2, G1 and G2 and total aflatoxins in a range of test samples that comprised: ginger, pepper, nutmeg, chilli, turmeric as individual spices and mixed pepper+chilli+nutmeg (90+5+5, m+m+m), mixed spice+ginger (6+4, m+m) mixed spice, mixed turmeric+ginger (2+8, m+m).

The validation was carried out over the following concentration ranges: aflatoxin B1 = 1 μg/kg to 16 μg/kg and total aflatoxins = 2,46 μg/kg to 36,1 μg/kg.

This document describes a method for the determination of the sum total of six ergot alkaloids (ergocornine, ergometrine, ergocristine, ergotamine, ergosine and ergocryptine) and their -inine epimer pairs by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) after clean-up by dispersive solid phase extraction (SPE).

The method has been validated for cereals and cereal-based food products.

The method has been validated in the range 13,2 μg/kg to 168 μg/kg for the sum of the twelve ergot alkaloids, in rye flour, rye bread and cereal products (breakfast cereal, infant breakfast cereal, and crispbread) that contained rye as an ingredient, as well as seeded wholemeal flour and a barley and rye flour mixture.

Method performance was satisfactory in the range 24,1 μg/kg to 168 μg/kg, however at lower concentrations RSDR values were greater than 44 %, and HorRat values exceeded 2,0, indicating the method may not be fully suitable at concentrations below 24 μg/kg for sum of ergot alkaloids, although it is suitable for screening at these concentrations. Method performance may be improved by inclusion of an isotopically labelled internal standard, but this was not available at the time of the method validation study.

1.1 This document specifies requirements for design, performance, safety and hygiene of refrigerated bulk milk coolers and the related methods of test.

NOTE The informative Annex J gives some elements regarding the estimation and calculation of energy consumption.

This document deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farm, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

It applies to refrigerated bulk milk tanks with air-cooled condensing units and automatic control intended for installation on farms or at milk collection points. It applies to tanks for two milkings (24 h), four milkings (48 h) and six milkings (72 h), in which the cooling takes place totally (non-pre-cooled milk) or partially (in case of pre-cooled milk) within the tank. It also applies to tanks in combination with a continuous system of milking (e.g. milking with robot).

1.2 This document does not cover:

— mobile tanks;

— tanks intended to be tilted for drainage;

— equipment for delivering the milk to the tank;

— equipment for pre-cooling of the milk;

— the hazards due to the use of other energy than electrical energy;

— pressure aspect of vacuum tanks (i.e. tanks where the inner part of the vessel is designed to operate at a pressure below atmospheric pressure).

1.3 Noise is not considered to be a significant hazard, but relevant for bulk milk coolers. This document therefore includes information in 7.1 and in Annex A concerning the manufacturer's declaration of the noise emission level of the cooler.

1.4 This document does not cover the calibration requirements for the tank to be used as a system for payment purpose.

1.5 This document is not applicable to bulk milk coolers on farm which are manufactured before the date of its publication as EN.
