This study was conducted to examine the usefulness of adding final probing step (step3) in dietary assessment by 24-hour recall method among Korean adults. One-hundred fifty five adults (37 males and 118 females) above 30 years of age who visited hospitals for health examination were recruited at three hospitals in Korea. One day dietary intake was obtained using 24-hour recall method from each subject. Dietary interview was conducted in 3 steps, (1) quick list of foods eaten during the previous day, (2) detailed information of all the foods eaten, (3) the final probing for any items forgotten. Items added at the step3 were identified and contributions of energy and nutrient intakes were calculated. The average duration of interview was 10.5 min, and time spent for each step was 4.12 minute for step 1, 5.62 minute for step 2, and 38 second for step 3. The average number of dishes reported by the subjects added at the step 3 was 2.2. (Males = 2.6, Females = 1.6) Frequently reported dishes in the step 3 were Beverage, Tea, alcohol (37.1%) and Fruits (31.8%). From mean total energy intake of 1,589 ㎉ (Men = 1,846 ㎉, Women = 1,509 ㎉), 179 ㎉ (11.3%) was added at the step 3. In the step 3, nutrient intakes increased significantly except retinol in total subjects and except retinol and cholesterol in males but all nutrients increased significantly in females. The final probing step can add significant information on intakes of foods and many nutrients with only about 38 seconds of interview time. Confirmation of the results with larger samples of different age groups is needed.

Chlorpyralid belongs to picolinic acid herbicide family targeting broadleaf plant such as clover and thistles. The action of this chemical is reducing or prohibiting the germination of grass, broadleaf weeds, and seedlings. An analytical method for the determination of Chlorpyralid residue in agricultural commodities was developed by Ministry of Food and Drug Safety (MFDS). For the analytical method verification, five representative commodities were chosen; chilli pepper for vegetable group, hulled rice for grain group, mandarin orange for fruit group, potato for root vegetables group and soybean for legume group. Briefly, sample were extracted with 5% formic acid in acetonitrile and partitioned by citrate buffer. To remove the interferences, dispersive-SPE using C18 and alumina neutral was used before LC-MS/MS (Liquid Chromatography -Tandem Mass Spectrometry) analysis with C18 column. The linear standard calibration curve was confirmed (coefficient of determination with calibration range). Mean average accuracies were shown 71.2~104.3 %. The precision were also shown less than 9.9% for all five samples. Is sum, the proposed method for Chlorpyralid residue determination developted by MFDS can be suitable for CODEX guidelines CAC/GL 40) and useful as official method.

Fluxametamid (IUPAC name: 4-[5-(3, 5-dichlorophenyl)-5-(trifluoromethyl)- 4, 5-dihydro-1, 2-oxazol-3-yl]-N-[(methoxyimino)methyl]-2-methylbenzamide) is isoxazoline insecticide and acarcide. An analytical method for the determination of fluxametamid residue in foods was developed as Ministry of Food and Drug Safety (MFDS) method. After extracting with acetonitrile, samples were partitioned and concentrated with dichloromethane. To remove the interferences, silica SPE cartridge was performed before LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry) analysis with C18 column. Five agricultural commodities (mandarin, potato, soybean, brown rice, and hot pepper) were used as group representative to verify. The linear matrix-matched calibration curve were confirmed (coefficient of determination > 0.99 with calibration range 0.01-2.5 mg/kg). Fluxametamid from sample with recoveris range from 82.24~115.27%. The precision were also shown less than 9.54% for all five samples. These spiked recoveries fall well within the recommened mean values in CODEX guideline for residue analysis (CAC/GL 40). Thus this method successfully processes food samples for Fluxametamid utilizing LC-MS/MS method.
