How dangerous is aflatoxin in peanut butter?
Aflatoxin is a potent human carcinogen. It is a naturally occurring toxic metabolite produced by certain fungi (Aspergillus flavis), a mold found on food products such as corn and peanuts, peanut butter. It acts as a potent liver carcinogen in rodents (and, presumably, humans).
Should I worry about aflatoxins?
An aspergillus infection can weaken the plants enough to reduce crop yield, which is a concern for the farmers. Chronic aflatoxin exposure can lead to liver damage or liver cancer, especially in individuals with pre-existing conditions such as a Hepatitis B infection.

How do you kill aflatoxin in milk?
Chemical approaches to reduce aflatoxin M-1 Chemical processes can be used to reduce, destruct, or inactivate AF in milk. They include ammoniating, acidic treatment, oxidizing, and reducing techniques. There are several issues and risks associated with these methods.
How do Aflatoxins cause cancer?
Dietary exposure to aflatoxins is among the major HCC risk factors. Aflatoxin B1, which is a genotoxic hepatocarcinogen, which presumptively causes cancer by inducing DNA adducts leading to genetic changes in target liver cells.
Is there aflatoxin in milk?
The hydroxymetabolites aflatoxin M1 (AFM1) and aflatoxin M2 (AFM2) can be present in milk and milk products when lactating cows or other mammals ingest contaminated feed [7].
How do you test aflatoxin in milk?
While these test strip techniques are handy in testing raw cow’s milk, the preferred methods for the analysis of aflatoxin in milk remain lab-based and include enzyme-lined immunosorbent assays (ELISA), fluorescence spectrometry and high-performance liquid chromatography (HPLC).
Does coconut oil have aflatoxin?
The total aflatoxin contamination in coconut oil ranged from 2.25 to 72.70μg/kg. Aflatoxin B1 contamination in coconut oil ranged from 1.76 to 60.92 μg/kg. Aflatoxin contamination in six other vegetable oil types tested were below 0.8 μg/kg.
Why is aflatoxin bad for you?
Aflatoxin exposure can cause nausea, vomiting, abdominal pain, convulsions acutely, and its chronic exposure can also lead to various complications like hepatotoxicity, immunotoxicity, and teratogenicity. Aflatoxin is one of the major causes of hepatocellular carcinoma in developing countries.
Do Almonds contain aflatoxin?
Abstract. In a survey of California almonds, aflatoxin was found in 14% of 74 samples of unsorted, in-shell almonds as received by the processor in 1972, but it occurred at very low levels (below 20 parts per billion [ppb]) in 90% of the contaminated samples.
How do you kill aflatoxin in food?
Oxidizing agents readily destroy aflatoxin, and treatment with hydrogen peroxide may be useful. Treatment of defatted oilseed meals with ammonia can reduce aflatoxin content to very low or undetectable levels with only moderate damage to protein quality.
