“…Results of this study are similar to the results obtained by Atanda et al [18], but higher than that estimated by previous studies of Zinedine et al [19], Heshmati and Milani [20]. Though these studies were on AFM 1 levels and occurrence in livestock milk not in livestock livers.…”

Liver as an organ of metabolism is disposed to toxins deposition and Livestock liver contributes to food security as major source of protein. Aflatoxin M1 (AFM1) is a carcinogenous metabolite aflatoxin B1 resulting from hydroxylation. To elucidate aflatoxin M1 incidence and levels in livestock livers from Minna-Nigeria, 24 hours fresh liver samples (n=122; 72 cow livers and 50 goat livers) were collected from five abattoirs and subjected to standard aflatoxin extractions via column chromatography and quantification by high performance liquid chromatography. Data showed the presence of AFM1 in some livestock livers. However, detected toxin levels in mean percentages and correlation of variation amongst the individual livestock livers was evident, with a 83.3% (60/72) incidence and a mean detection level of 1.464 µg/kg in cattle livers, as compared to 58.0% (29/50) incidence and a mean of 0.425 µg/kg in goats livers. Contamination in some samples; 52% (26/50) of goat liver and 62.5% (45/72) cow liver exceeded the EU, US and FDA limit of 0.05 µg/kg, indicating human exposure to animal liver with high level aflatoxin contamination. Therefore, there is a need to limit the exposure to aflatoxin by enforcing regulatory limits on animal feed.

“…Only 5.53% decrease was recorded with the control (Sc) samples. This slight decrease in the level of AFM1 in Sc samples could be attributed to binding of the AFM1 with the trace levels of dead bacterial cells as previously reported by different researchers [34,35]. It is trace because the milk sample was immediately sterilized after collection, and no time was allowed for the proliferation of the bacteria that might probably present.…”

“…bulgaricus, and Bifidobacterium lactis), alone or in combination, in UHT (ultrahigh temperature) skim milk. On the other hand, other researchers showed that the binding ability of AFB1 to LAB is strain specific [18,34,41]. Regarding the effect of pH change during ergo fermentation, Elsanhoty et al (2014) [18] considered the pH change during fermentation as a factor affecting the binding interaction and showed an increase in the level of AFM1 reduction by the decrease in pH during bacterial treatment.…”

In this study, the reduction of aflatoxin M1 (AFM1) levels during lab-scale ergo production was investigated through determination of the residual levels of AFM1 using Enzyme Linked Immunosorbent Assay. The results showed gradual and incubation time dependent reduction of AFM1 level in the raw milk samples being fermented to ergo. The maximum reductions of 57.33 and 54.04% were recorded in AFM1 in natural and LAB inoculums initiated fermentations, respectively, in 5 days of incubation. Although a significant difference ( = 0.05) in the AFM1 decrease in the two types of fermentations was recorded, such findings could vary with milk samples depending on initial load of the microorganisms as determined by hygienic conditions. However, the level of AFM1 in control (sterilized) samples showed only a 5.5% decrease during the entire period of incubation. Microbiological investigation showed increasing LAB counts with incubation time. A gradual decrease in pH of the milk samples was observed during fermentation. Considering the fact that both viable and dead bacterial cells could remove AFM1 during ergo production, the mechanism is proposed as predominantly involving noncovalent binding of the toxin with the chemical components of the bacterial cell wall.

“…[20] investigated 85 pasteurized milk samples were analyzed for aflatoxin M1 with the ELISA technique. Seventy-five samples were found to be contaminated with aflatoxin M1and the range of aflatoxin M1 was (27-48 ppb), While [21] revealed that the level of aflatoxin M1 ranging from 0.001 to 0.117 ppb. [22] measured aflatoxin M1in pasteurized milk samples from the School Milk Project in Thailand and The highest concentration of aflatoxin M1 found in school milk samples was 0.114 ppb, whereas [23] revealed that the range of aflatoxin M1 in pasteurized milk ranging from (0.023-0.154 ppb).…”

Abstract--The current study was designed to investigate the presence of aflatoxin M1 in 25 samples of pasteurized canned milk which collected randomly from some Iraqi local markets using ELISA technique.Aflatoxin M1 was present in 21 samples, the concentration of aflatoxin M1 ranged from (0.25-50 ppb). UV radiation (365nm wave length) was used for detoxification of aflatoxin M1 (sample with highest concentration /50 ppb of aflatoxin M1 in two different volumes ((25 & 50 ml)) for two different time (15 & 30 min) and 30, 60, 90 cm distance between lamp and milk layer were used for this purpose). Results showed that distance between lamp and milk layer was the most effective parameter in reduction of aflatoxin M1, and whenever the distance increase the effect also increase.
