ABSTRACT The first aim of this paper was to evaluate pesticide residue levels of berry fruit samples. The second aim was to analyze health risks associated with pesticide levels. The monitoring was conducted on samples from producers in north-eastern Poland, during the time period 2005-2010. In total, 241 samples of berry fruit were analyzed using validated and accredited multi residue methods. The studies included 7 commodities (125 strawberry, 59 black currant, 25 raspberry, 23 chokeberry, 7 red currant samples and one sample of elderberry and wild strawberry), and the analysis of 128 pesticides. Residues, mainly insecticides, were found in 47.7% of samples while 40.7% of samples contained pesticide residues below MRLs and 7% above MRLs. The pesticides were found most often in red currant (100%) and black currant (63%) samples. The most frequently detected pesticides were fenazaquin and fenitrothion. Pesticide residues at levels exceeding legally binding MRLs occurred mostly in black currant samples (12 samples). Violations of the maximum residue limits (MRLs) (15 notifications) and use of a forbidden plant protection product (8 notifications) were found in twenty-three berry samples during the six-year study. For these cases, the RASFF system (rapid alert system for food and feed) procedures were initiated. The highest number of notifications was recorded in 2008 (11 notifications). Only one of the notifications was prepared for berry fruit from an integrated production system − black currant, the remaining were for conventional fruit. Among the RASFF notifications, 17 (74%) were for black currant samples.The estimated exposure to pesticide residues detected in the analyzed berry fruit samples was shown to be very low for the general population (adults) and for the critical population of small children. Acute and chronic exposure based on residue levels did not adversely affect consumer health.

Abstract During the 2010-2011 seasons, analyses of 171 samples of fresh fruit from the south-eastern region of Poland were performed. The research program included the determination of 137 (in 2010) to 152 (in 2011) active substances, together with their metabolites and decomposition products. The analytical methods used in the research were gas chromatography (GC/ECD/NPD) and spectrophotometry (to determine residues of dithiocarbamates). The results were compared with Poland’s allowed maximum residue levels (MRLs).Residues of active plant protection product substances were detected in 85 samples (50%), while 7 (4%) samples had exceeded the MRLs.Violations of MRLs were mainly concerned with the following group of insecticides: cypermethrin (in black currant), esfenwalerate (in raspberry), and the fungicides: propiconazole, and difenoconazole (in gooseberries).

The significance of this study is reflected in proving the reliability of the ELISA test for the detection of aflatoxin in food and feed. Verification tests were based on the use of reference materials with known concentrations of aflatoxins, contamination of samples by adding known concentrations of analyte and participation in inter-laboratory studies, by different perpetrators and different laboratories. By measuring the known con?centrations of analytes it was proved that aflatoxins, in the selected samples, were determined in accordance with the requirements defined for a given method, and it was demonstrated that it is possible to determine the level / concentration of mycotoxins in relation to the MRL defined by the Regulation on amendments to the Ordinance on the maximum allowable residue levels of pesticides in food and feed and feed and feed for which maximum allowed quantities of residues of plant protection products (Sluzbeni Glasnik RS broj 28/2011 clan 2. prilog 5. tacka 2).

Abstract Extensive use of pesticides in agriculture can lead to contamination of fruit harvests and an increased risk of toxic effects on humans. A total of 123 fruit samples harvested in 2012 in the north-eastern region of Poland were analysed for pesticide residues as part of the national monitoring programme, and as part of research commissioned by private customers. Pesticide residues were found in 64.2% of the samples. There were pesticide residues below the maximum residue level (MRL) in 63 (51.2%) of the samples, while 16 (13%) exceeded MRLs set by Regulation (EC) 396/2005. The gooseberry, currant, and strawberry samples showed the most contamination. The most frequently detected pesticides were dithiocarbamates (54) followed by difenoconazole (22), boscalid (17), and alpha-cypermethrin (15). More than half of analysed samples had multiple residues (up to 8 residues), with multiple residues most common in gooseberry and currant samples. This study shows cases of non-authorised pesticide use by farmers who are trying to protect certain fruit.

The main goal of the scientific institution was and remains to improve the assortment of fruit and berry crops for the development of domestic horticulture. Black currant breeding at VNIISPK was started by A.F Tamarova and continued by the doctor of agricultural Sciences T.P.Ogoltsova and doctor of agricultural Sciences S.D. Knyazev. A long-term breeding program has been developed. The main goals of the program are to create black currant cultivars with continuous resistance to diseases, first of all powdery mildew, as wells resistance to pests, i.e. bud mite. As a result of the long-term work, over 40 black currant cultivars have been developed, 14 of them are zoned. Red currant breeding was led by the candidate of agricultural Sciences L.V. Bayanova; since 2001 the work has been continued by the candidate of agricultural Sciences O.D. Golyaeva. ‘Heinemanns Rote Spӓtlese’, the descendant of R. multiflorum Kit., was involved in the red currant breeding for the first time in Russia. On its genetic basis, a series of late maturing cultivars with long and dense racemes was created. At the Institute, in total 21cultivars of red currants have been developed, 13 of them are zoned. At present, red currant cultivars make up 25.5% of the zoned assortment in Russia. The first research on gooseberries was stated by V.P. Semakin and A.F Tamarova; since 1992 the systematic gooseberry breeding has been carried out by the candidate of agricultural Sciences O.V. Kurashev. On the basis of Grossularia robusta, we have created gooseberry forms that are resistant to powdery mildew and leaf spots. These forms are highly productive, weakly thorned, having bush habit suitable for mechanized harvest. The result of breeding activities was the transfer of 6 gooseberry cultivars to State agricultural testing: ‘Solnechny Zaychik’, ‘Nekrasovsky’, ‘Yupiter’, ‘Zemlianichny’, ‘Moryachok’ and ‘Discovery’.

The article highlights the results of research carried out in 2019-2020 to study the reasons for the drying out of the stems of black currant (Ribes nigrum L.), red currant (Ribes rubrum L.) and golden currant (Ribes aureum L.). As a result of research, the fungus Sphaeropsis malorum Peck. in the first in Russia it was revealed from the drying stems of three types of black currants, red currants and golden currants. This  pathogen inhabited currant stems together with fungi from the genus Cytospora spp., causative agents of stem drying. On red currants, it was established that S. malorum was the main causative agent of branch drying, as indicated by the high frequency of occurrence (75.0-83.3 %) of this fungus on the affected stems, compared with species from the genus Cytospora spp. (16.7-33.3 %) and Phomopsis ribesia (25.0 %). Due to the fact that the cultivation of currants in the immediate vicinity of apple and pear trees leads to infection of plants with the fungus S. malorum, it is necessary to avoid planting currants in the vicinity of fruit-bearing seed gardens.

Chemical characteristics of fruit spirits produced from three black currant cultivars (Malling Juel, Ometa, Ben Sarek) and two red currant cultivars (Rondom and Versailles) grown in Serbia were examined using gas chromatography. In addition, sensory evaluation of the spirit samples was performed using the Buxbaum model of positive rating. Fruit spirits produced from black currant cultivars displayed the highest contents of methanol (267.2 - 595.0 g/hl A. A) and amyl alcohols (74.2 - 204.8 g/hl A. A). Total sensory scores of currant brandies ranged between 17.60 and 18.40, while currant brandy produced from Ben Sarek black currant cultivar received the highest score (18.40). All tested samples of currant brandies fulfilled EU requirements as regards their content of methanol and other components such as acetaldehyde, ethyl acetate and high alcohols. The currant distillates were compared with other commercial spirits, including plum and grape brandies.
