BACKGROUND The major contaminants usually encountered in milk and milk products include pesticide residues, heavy metals, and aflatoxin M1 (AFM1). Primarily, milk get contaminated before milching, from the cattle feed, from sources/materials used during the processing of milk as well as improper handling of the milk during the pre- and postprocessing period. OBJECTIVE The purpose of this stud...

Despite of beneficial effects of antibiotics in treatments of infectious diseases, antibiotic residues in meat, milk, eggs and another products can cause serious side effects for human health. It is clear that, antibiotic residues in food stuff, cause bacterial resistance, allergic reactions, toxicity, carcinogenic effects and change of natural micro flora of intestine in consumers. So, the aim...

AIM The study was conducted to detection and determination of concentration or level of antibiotic residues in milk and egg of local and commercial farms at Chittagong during December 2011 to June 2012. MATERIALS AND METHODS A total of 400 (200 milk and 200 egg) samples were collected from local and commercial dairy cows and local scavenging and commercial poultry farms, respectively. Microbi...

Prevention of antibiotic residues in milk is an important aspect in milk production to ensure health protection for the consumer and high quality of milk for dairy processing. Limited information is available on the potential impact of milking frequencies associated with Automatic Milking (AM) on excretion of veterinary drugs in milk. Under experimental conditions the excretion of antibiotics i...

The aim of this work was to study possibilities of using microbiological broadspectrum inhibitor test (Delvotest T) for express estimation of antibiotic residues in bovine milk. For quantitative estimation the waste-milk samples were stepwise diluted (dilution array) by antibiotic-free milk until negative test result was achieved. Another objective was to evaluate heat treatment efficiency of w...

Milk is a food rich in nutrients, which makes it widely consumed Brazil. Its quality vital for the safety of consumers. Antimicrobial residues may be present milk if proper management not performed administering veterinary drugs to treat dairy cattle, thus representing risk human health and generating losses manufacturing products. Therefore, this study aimed evaluate presence antimicrobials na...

The veterinary drugs residues are also important pollutants found in milk, since veterinary drugs are commonly used in cattle management. Considering the role of milk in human nutrition and its wide consumption throughout the world, it is very important to ensure the milk quality. A quantitative structure–retention relationship (QSRR) was developed using the partial least square (PLS), Kernel P...

A previous study carried out by the Center for the Biology of Natural Systems (St. Louis) in Guatemala (OLSZYNA-MARZYS et al. 1973) reported abnormally high concentrations of DDT in samples of mother's milk from donors in three rural Pacific coast communities. In that survey of forty-six donors, total DDT was found to be as high as 12.2 ppm, 244 times the maximum permissible concentration for m...

In this study, antibiotic residues in raw milk and pasteurized milk products sold in AnkaraTurkey investigated. For this purpose; a total of 240 milk samples, which contains 10 raw and 10 pasteurized milk samples per month collected from various markets in Ankara between April 2003 and March 2004 were analyzed in terms of penicillin G, oxytetracycline, gentamicin, streptomycin and neomycin by u...
