“…According to the Ministry of Agriculture, Forestry, and Fisheries, Japan (MAFF), concentration less than 10 Bq/kg in drinking water, less than 50 Bq/Kg in milk and infant foods, and less than 100 Bq/Kg in meat and fish are acceptable for human consumption ( Manabe et al , 2016 ). The results are somehow consistent with the findings of Brandhoff et al (2016) , who reported that different food samples, including dairy and meat, were subjected to the analysis of selected radionuclides in meat but are less than the acceptable limit. The results were further supported by the findings of Miyazaki et al (2013) who depicted that about 300 samples were determined for the presence of radioactive iodine ( 131 I) and cesium ( 137 Cs and 134 Cs) and it was found that only few samples showed some contamination, but below the regulatory limits.…”

Animal-origin food products pose serious threat to public food safety due to high microbial loads. The microbial and radioactive contaminations in commercial cold duck meat products were evaluated. Ten different lots of commercial samples (C1-C10) were classified based on type and smoking process. All samples were highly contaminated (< 4-7 Log CFU/g) with total aerobic bacteria (TAB), yeasts and molds (Y&M), and 7 samples (C1-C7) were positive for coliforms. Furthermore, three samples were contaminated with Listeria monocytogenes (C4-C6) and one with Salmonella typhimurium (C6). No radionuclides (131I, 137Cs, and 134Cs) were detected in any sample. The results of DEFT (direct epifluorescent filter technique)/APC (aerobic plate count), employed to screen pre-pasteurization treatments of products, indicated that smoked samples were positive showing DEFT/APC ratios higher than 4. Notably, the samples showed a serious threat to microbial safety, thus were irradiated with electron-beam (e-beam). The D10 values for S. typhimurium and L. monocytogenes were 0.65 and 0.42 kGy, respectively. E-beam application at 3 and 7 kGy resulted in reduction of initial TAB, Y&M, and coliform populations by 3 and 6 log cycles, respectively. Thus, e-beam was proven to be a good decontamination approach to improve the hygiene of cold duck meat.

“…This method is suitable for separating radioactive material from the whole sample; vi) in chemical separation, different methods such as deposition, ion exchange, distillation, and electrolysis are used (Harley, 1979 ). In this case, when the level of some actinides such as Pu, Th, and U isotopes is less than the 0.1 maximum permitted levels, and the sample size is large, the separation will be done by ion exchange or chromatography column (Caroli et al , 2013 ; Brandhoff et al , 2016 ).…”

“…Accurate chromatography separation is essential so that the signals are separated and do not interfere with one another, as they reduce the detection limit (Brandhoff et al ., 2016 ). In certain cases, selective solvents used to extract the radioactive isotopes are employed to increase the analysis rate.…”

Contamination of food and water with radioactive substances is a serious health problem. There are several methods to detect and measure radioactive materials, some of which have been developed in recent years. This paper aims to discuss the methods of detecting and measuring radioactive substances in food and water. The principles and the advantages and disadvantages of each method have been discussed. The results showed that some of these methods, such as spectrometry γ-ray high purity germanium, portable radon gas surveyor SILENA, RAD7, and inductively coupled plasma mass spectrometry, have a higher sensitivity for detection and measurement. Also, the spectrometry γ-ray high purity germanium method has attracted more attention than other methods because it can measure a wide range of radionuclides with high resolution.

“…An overview of samples taken between 2010 and 2013 showed that only 7 out of 585 vegetable samples (not specified which vegetables) contained radionuclides. Again these positive samples concerned wild mushrooms with levels below the EU limit (Brandhoff et al, 2016).…”

A risk-based approach helps focus on the most relevant food safety hazards for human health to be included in a monitoring program. These can be identified based on information on the occurrence and severity of the hazards. For this purpose, a long list of hazards that may occur was established and prioritised based on frequency of detection and levels found. When this prioritised list is combined with information on the severity of a hazard (which is based on toxicological information) and Dutch consumption data, a short list of hazards can be compiled to include in a monitoring program. This report describes the results of a literature study performed to identify chemical hazards in leafy vegetables. The report is part of a series of reports on chemical hazards in food crops for which previously mushrooms, fruits and cereals, seeds and nuts were investigated. Long list of chemical hazards that might occur in leafy vegetablesA long list of chemical hazards possibly present in leafy vegetables was established by performing a literature study using pre-set search terms in Scopus and Web of Science. In total, 420 hits were evaluated for their relevancy resulting in 169 papers that were read in full and for which information was extracted in an Excel document. Additionally, a Google search was performed in four websites to obtain reports on the occurrence of chemical hazards in leafy vegetables, resulting in 31 relevant hits that were also summarised in the Excel document. Furthermore, for hazard groups that retrieved a limited number of papers, an additional literature search was performed resulting in 27 relevant papers. Based on the papers obtained, a long list of chemical hazards was extracted, which contained heavy metals, nitrate and nitrite, polycyclic aromatic hydrocarbons (PAHs), pharmaceuticals, personal care products and endocrine disrupting compounds, flame retardants, perfluor compounds, radionuclides, nanoparticles, plant protection products (PPPs), mycotoxins, plant toxins, cyanotoxins, processing contaminants, and cleaning agents and disinfectants. The majority of the papers described experimental studies on the possible uptake and accumulation of chemical hazards from the environment into leafy vegetables and most information was available for lettuce followed by cabbage and spinach. Intermediate list of prioritised chemical hazards in leafy vegetablesThose hazards that were frequently found in leafy vegetables, detected above (EU) legal limits, or reported to lead to exceedances of health based guidance values were included on the intermediate list.The following substances were included on the intermediate list from the heavy metals and elements section: aluminium, cadmium, copper and lead. These substances either exceeded the EU maximum limit (ML) or leafy vegetables were seen as major contributor to the substance's acceptable daily intake (ADI). Manganese (Mn) was identified as knowledge gap, since an experimental study, in which lettuce was hydroponically grown in Mn contaminated medium, resulte...
