This study was conducted to evaluate and compare the levels of aflatoxin M1 in raw and pasteurized milk samples during different seasons by Enzyme- Linked Immuno Sorbent Assay in Sanandaj, Iran. In 257 (94.49%) out of 272 milk samples the presence of aflatoxin M1 was detected in concentrations ranging between 0.007 and 115.930 ng/l. AFM1 level in 12 (4.4%) of positive samples were higher than t...

The dairy farmer has the responsibility of producing milk under clean and hygienic conditions, employing appropriate techniques to clean and disinfect the milking equipment and the milking parlour. The ability of raw milk to retain its quality under storage, and the safety of the product for the consumer, can both be directly related to the bacterial content of the milk. In most countries, bact...

During the past three years we have had a considerable number of cases of scurvy develop in infants being fed on pasteurized milk. In 1912, when the first cases were noted, we were pasteurizing the milk in our own diet kitchen, heating it to a temperature of 165 F. for twenty minutes. At this time several cases of scurvy developed, owing to the fact that through an oversight orange-juice was no...

During a recent outbreak of listeriosis, we examined 121 raw milk samples and 14 milk socks (filters). Listeria monocytogenes was recovered from 15 (12%) of 121 milk specimens and 2 (14%) of 14 milk socks. The optimal processing method consisted of cold enriching diluted milk for 1 month with culture to selective broth, followed by plating.

Escherichia coli O157:H7 is a potentially lethal pathogen which has been responsible for several outbreaks of milk-borne illness in recent years. The objective of this study was to evaluate the survival and metabolic activity (indexed by bioluminescence) of a chromosomally lux-marked strain of E. coli O157:H7 in raw, pasteurized and microfiltered pasteurized milk at 4 and 20°C for up to 14 d.
