Succintă analiză comparativă între obiectele lumii tradiționale, ca elemente identitare, și obiectele lumii postmoderne, ca bunuri de consum

This paper aims to present the influence of the consumer society on the way we relate to objects. Comparing the way of reporting to the object of the traditional world and of the consumer society we can observe significant changes. The consumer society promotes a certain standard of life that you can only access through consumption. In the paper I pointed out that the objects of the traditional Maramureș world have profound meanings, they represent a symbol between generations. The traditional object is characterized by sustainability as opposed to that of the consumer society whose life is very short. The consumer society creates artificial needs that deepen the dissatisfaction of not owning enough. In a society that incites to unlimited consumption, building a moral attitude based on discernment is of utmost importance

Research regarding the qualitative assessment of the contamination with antibiotic residues from the milk sold in the agro-food markets and in the commercial network in Iași

The marketing of antibiotics directly to animal owners and the intensification in recent years of the use of these drugs without the recommendation of a veterinarian has led to the increasingly frequent presence of antibiotic residues in milk that is intended either for human consumption or for obtaining dairy products. The use by processors of milk with antibiotic residues is difficult to achieve. According to European Union food safety legislation, milk harvested from cows treated with antibiotics must be collected separately, and isolated. It cannot be given for processing or human consumption. Applying thermal treatment, especially pasteurization, to milk with antibiotic residues above the maximum allowed limit has insignificant effects, processors have been convinced of this over the years. The interest of the study for the detection of antibiotic residues in milk is very current, even if the waiting period after treating the cows with antibiotics is recommended, often this period is not respected, the consideration being the significant economic losses. The rapid strip test method was done with strip tests AuroFlow, which are designed for the simultaneous detection of beta-lactams and tetracyclines. The working samples were represented by processed milk sold in supermarkets and raw milk sold in agro-food markets in Iasi. The distribution of processed milk samples was 1 positive sample each in 2 of the supermarkets where the samples were collected, these being in the percentage of 4%. UHTtreated milk in all 5 supermarkets did not show any positive tests. On the other hand, the sale of raw milk in the agrifood markets showed a percentage of 20% positive samples, out of several 25 samples examined, the rate is much higher compared to processed milk

Microbiological quality of chicken meat: Campylobacter relevant public health problem

Campylobacter is undoubtedly an important public health problem that European legislation (Directive 2003/99 / EEC) establishes as zoonotic agent to be monitored, with mandatory notification of the number of isolates, registration of cases, and the provision of information to Member States. However, despite its high prevalence, so far they have not established measures for its reduction or the obligation to implement control plans. Unlike Salmonella, which, most likely, thanks to community prevalence reduction targets and national control plans, still, for years, a marked downward trend in the number of cases in the EU. Consumption of contaminated chicken meat, mainly by Campylobacter jejuni is the leading cause of human campylobacteriosis in Europe, so it EFSA considered necessary to establish measures to reduce Campylobacter in chicken flocks. According to the European Food Safety Agency (EFSA), a real incidence of 9 million annual cases of campylobacteriosis in the EU is estimated. The average prevalence of Campylobacter in broiler flocks at Community level is 71.2%, with 75% in the case of Romania, it is therefore a major problem. A lot of birds that come to slaughter excrete the bacteria in their feces and is very difficult to prevent, during processing, contamination of carcasses and abattoir equipment occurs. Therefore it is important to reduce the bacterial load in birds before arrival at the slaughterhouse. As the reports of the EFSA and the European Center for Disease Prevention and Control (ECDC), based on the results of monitoring activities of zoonoses (diseases transmitted naturally from vertebrate animals to man diseases), carried conducted in 2015 in 32 European countries (28 Member States and four non-Member States), campylobacteriosis is the most commonly reported zoonosis. In view of this trend, the European Union is preparing a draft regulation that will come to amend the current legislation for the control of Campylobacter. Those rules shall establish a process hygiene criterion for Campylobacter in broiler channels to control possible contamination with this bacteria during the slaughter stage. This draft European regulation also establishes a contamination value above which corrective action is required to maintain hygiene, according to food legislation (20% of chicken carcasses with a level of Campylobacter ≥ 1000 cfu / g, for 2025). The European Commission considers that this approach should be implemented gradually and tighter over time

Correlations between the adaptive capacity in Bucovina of Limousine cows and the nutritional quality of the milk

The Limousine breed is spread on all continents in 64 countries, and Romania will be the 65th country in which it is trying to adapt this breed of cattle. Limousine is currently ranked No. 1 in England and is highly regarded in other countries, including France, No. 2, Canada, No. 2, Italy, and the United States. 3rd place. The main objective of this project is to observe the adaptability of the Limousine breed to the geo-meteorological conditions recorded in northern Romania, the Bukovina region. The aim of the paper is to evaluate from a nutritional qualitative point of view the raw milk obtained from this breed. The investigations were carried out to establish the degree of freshness, integrity and we monitored some physical-chemical and hygienic parameters of the raw material milk. Sampling was done directly from the collection vessels after milking and filtration mainly in the hot season, and their processing was done in the Food Control Laboratory of the Faculty of Veterinary Medicine Iasi, where a number of 38 milk samples were processed. Following the analysis of the samples, a number of 8 samples were inadequate in terms of organoleptic examination and integrity. Deviations from the organoleptic characteristics of the parameters of appearance, color, smell, and taste represented a percentage of 21.05%. The determinations of the Physico-chemical parameters were classified as inappropriate a number of 10 samples which represents a percentage of 26.31% of the total samples collected

Necrotic enteritis in meat chicken raised at the ground in permanent bedding

Poultry necrotic enteritis is an acute clostridial infection characterized by severe necroses of intestinal mucosa. The disease begins suddenly, with a sharp increase in death rate and dehydration. Clostridium perfringens, a sporulated, anaerobic, Gram-positive bacterium is commonly found in the environment and in the gastrointestinal tract as part of the normal intestinal flora. Frequent presence in the digestive tract of healthy birds is associated with necrotic enteritis in broilers. The research was conducted on 323 samples (120 live chickens, 89 corpses, 104 feed samples and 10 water samples) collected from a farm with 32 253 hybrid Ross 308 broilers (21 days), raised at the ground on permanent bedding, where there was a significant increase in mortality above the permissible limit. The necropsy performed on 980 chicken corps revealed a different prevalence of intestinal tract lesions: bleeding wall (28.37%), mucosal necrosis (23.22%), gas content (18.57%), mucosal inflammation (15.73%) and red orange mucus in the intestines (14.10%). Bacteriological examination identified Clostridium perfringens in 11.66% of live broilers, 10.11% of chicken corps, 61.53% of feed samples and 3.09% of water samples. Increased percentage this species isolation suggests that feed taken from the hall was an important source of infection for broilers reared on the ground

Fish meat – a potential danger for consumers`health

Fish is an excellent source of Omega 3 protein and fatty acids, which have the property of reducing cholesterol, maintaining a healthy heart, and even helping to prevent depression. Also, meat fish is a lean meat with low calorie but delicious assortment of meat, and is recommended in the consumer's diet . The fish content vitamins (A, D, E, B12), minerals (phosphorus, iodine, potassium) and healthy fats that can not be synthesized in the human body and must be fed through food. How healthy the fish meat is, the more dangerous it can be in terms of its safety for the consumer, and more precisely the presence of parasitic hazards. The main objectives of this paper are to describe the parasitic hazards of fish meat to indicate the proper preparation of fish meat and to increase consumer awareness of the risks associated with the consumption of this type of meat, threats of parasitic nature. Avoiding the consumption of untreated or poorly treated fish meat is one of the preventive measures that need to be taken to avoid fish parasites

Preliminary study on the impact of non-thermal plasma activated water on the quality of Triticum aestivum L. cv. Glosa sprouts

The present study aimed to investigate the effects of non-thermal plasma-activated water (PAW) on Triticum aestivum L. cv. Glosa sprouts. Two types of PAW were generated by exposing distilled water to a high-voltage electric discharge. Wheat caryopses were treated either with PAW1 (25 mg/L NO3 −, 4 mg/L NO2 −, and 6 mg/L H2O2 ) or PAW2 (35 mg/L NO3 −, 5 mg/L NO2 −, and 7.5 mg/L H2O2 ) for 8 days, with samples being collected at days 1, 2, 3, and 8. The germination rate, growth parameters, protein, photosynthetic pigments, total phenolic contents, antioxidant activity of free and bound phenolic fractions, and activity of antioxidant enzymes were evaluated. Both PAW1 and PAW2 had positive effects on Triticum aestivum L. cv. Glosa sprouts. PAW2 had a better impact on sprouts with respect to growth parameters, free phenolic content, and antioxidant activity of the free phenolic fraction (day 3), the accumulation of proteins, and photosynthetic pigments (day 8). In conclusion, exposure to PAW increases the quality of Triticum aestivum L. cv. Glosa sprouts. Further optimization of PAW treatment is required for the most favorable impact on the accumulation of biomass and health-promoting compounds in sprouts

Effect of sea buckthorn and vitamin E on growth performance of Acipenser stellatus (Pallas 1771) juveniles

Addition of natural additives (prebiotics, probiotics, phytobiotics) in fish feed is a benefic method because it leads to improved growth performance of fish reared in intensive production systems. Sea buckthorn is one of the most commonly phytobiotics used in aquaculture because of its antioxidant, antimicrobial, immunostimulant, anti-stress, cytoprotective, liver and tissue regeneration properties. Sea buckthorn berries are rich in vitamins (B, C, E and K), flavonoids, carotenoids, tocopherols and many volatile compounds. In this context the aim of this study was to evaluate the effects of dietary vitamin E (500 mg/kg diet) and sea buckthorn on growth performance and survival of the A. stellatus juveniles reared in a recirculating aquaculture system. The experiment took place in the recirculating pilot system of “Dunărea de Jos” University of Galați. In order to emphasize the influence of the above mentioned immunostimulants on sevruga fingerlings with different genetic background, four experimental groups from different genitors (V1: ♀2 Danube x ♂1 Aquaculture, V2: ♀1 Danube x ♂1 Danube, V3: ♀1 Danube x ♂2 Aquaculture and V4: ♀2 Danube x ♂2 Danube) have been used. At the end of the experiment no significant differences (p>0.05) were observed in terms of final mean weight, individual growth rate, SGR, FCR, PER, between the sevruga fingerlings obtained from wild genitors, comparing with those obtained from aquaculture genitors

Staphylococcus aureus isolated from intramammary infection in immunologically protected goats

In a goats farm with 86 goats immunologically protected by vaccination against gangrenous mastitis, evolved clinical and subclinical intramammary infections. 30 milk samples from goats with clinical mastitis evolving and 16 milk samples from apparently healthy goats were collected. Following bacteriological exams 36 Staphylococcus aureus strains were isolated and identified using standard protocols, 25 (69.44%) being isolated in pure culture and 11 (30,55%) in association with other bacteria: Escherichia coli, Pasteurella haemolytica, Klebsiella oxytoca. Bacterial strains were morphologically identified using Gram staining and biochemical tests. The antibiotic susceptibility was tested for 15 strains of Staphylococcus aureus on 10 antibiotics and showed similar patterns
