milk and milk products containing antibiotics especially penicillin may present a health hazard to individuals who are super sensitized to penicillin. a total of 620 samples of raw milk which were delivered to tehran pasteurization plant were examined. 294 samples were antibiotic-negative and 326 samples showed to contain antibiotic. considering the results obtained, certain recommendations wer...

Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...

The control of veterinary drug residues in milk is performed in Slovenia. The monitoring of antibiotic residues in milk began in 1977. In the last four-ye­ ar period (1995-1998) a total of 3358 samples were analysed and the majority of them (99.4 %) were negative. Antibiotics were found in only 19 samples. De­ termination of sulfonamides in milk was introduced in 1995. In four years we examined...

AIM The present study was conducted to find the organochlorine pesticide (OCP) and organophosphorus pesticide (OPP) residues in fodder and milk samples along Musi river belt, India. MATERIALS AND METHODS Fodder and milk samples collected from the six zones of Musi river belt, Hyderabad India were analyzed by gas chromatography with electron capture detector for OCP residues and pulsated flame...

The content limit for allatoxin B1 in feedstuffs of the European Common Market Commission can result in the presence of aflatoxin in milk, Traces of aflatoxin have been found in milk, depending on the feedstuff used, feeding conditions and the season of the year. These results were confirmed by thin-layer chromatography, by chemical reactions and by fluorescence spectra. Metabolic investigation...

Mastitis is known as the most common disease syndrome in the dairy industry. Treating mastitic lactating animals with antibiotics is a veterinary practice to cure the disease. However, the antibiotic used may persist in the milk for a period of time depending on drug selected, dosage applied, route administered, body weight of the animal treated, etc. Antibiotic residues in milk are of great co...

BACKGROUND AND AIM There are global public health and economic concerns on chemical residues in food of animal origin. The use of antibiotics in dairy cattle for the treatment of diseases such as mastitis has contributed to the presence of residues in dairy products. Penicillin residues as low as 1 ppb can lead to allergic reactions and shift of resistance patterns in microbial population as we...

INTRODUCTION Tetracyclines (TCs) are widely used in animal husbandry and their residues in milk may resultin harmful effects on human. The aim of this study was to investigate the presence of TCs residues in various bovine milk samples from local markets of Ardabil, Iran. METHODS One hundred and fourteen pasteurized, sterilized and raw milk samples were collected from markets of Ardabil. Tetr...

Thirty-one batchor continuous-flow milk pasteurizers used on commercial dairy and custom calf-feeding operations were surveyed. One sample of raw waste milk (RWM) immediately prior to onfarm pasteurization and one sample of pasteurized waste milk (PWM) immediately after on-farm pasteurization from daily waste milk pools were evaluated. The RWM and PWM samples were evaluated for nutrient composi...
