MANILA, Philippines — The Food and Drug Administration (FDA) has warned the public against peanut products, including those sold by ambulant and street vendors, after receiving reports about those found to be laden with cancer-causing fungal contaminant.

In an advisory, FDA acting director general Kenneth Hartigan Go said they have tested some pre-packed peanuts positive for Aflatoxin B1, a by-product of molds.

Aflatoxin B1 is said to be one of the most naturally occurring carcinogenic mycotoxins produced by certain species of fungi.

“Aflatoxin binds proteins, vitamins, and minerals so that the body cannot absorb the nutrients. In children, aflatoxin can stunt growth and can lead to kwashiorkor, a debilitating disease of nutritional deficiency in children. If ingested over a prolonged period of time in large doses, the poison can also inhibit the immune system,” Go said.

He added that the mutations of cell DNA (deoxyribonucleic acid)  due to prolonged exposure to aflatoxin would increase the risk of developing cancer cells.

Peanuts are agricultural crops that are dried after harvesting. If not properly dried, molds can grow on the raw peanuts easily, causing them to rot. As the molds feed on the grain, they produce waste products known as mycotoxins.

The FDA did not disclose the brands of the pre-packed peanuts that they found laden with aflatoxin, as of Thursday, saying that an investigation on the possible source of the contamination has been ongoing.

from The Global Dispatch, Thursday, Jan 23rd, 2014:

Peanuts are agricultural crops that are dried after harvesting. If not properly dried, molds can grow on the raw peanuts easily, causing them to rot. As the molds feed on the grain, they produce waste products known as mycotoxins.

Aflatoxin is a mycotoxin, a natural toxin produced as a secondary metabolite to certain strains of the fungus Aspergillus, in particular Aspergillus flavus and Aspergillus parasiticus.

The toxin is then excreted onto plants or pre-processed foods, some intended for human consumption.

Aflatoxin poisoning can be broken up into acute and chronic disease depending on the amount of toxin ingested. When people (or animals) ingest aflatoxin contaminated foods, the liver is the main target for disease.

There is a direct link between aflatoxin poisoning and liver cancer. Liver cancer or hepatocellular carcinoma is an important public health concern in many parts of the world due to aflatoxin. In some countries, acute aflatoxin poisoning results in liver failure and death in up to 40% of cases.

Prevention and control of aflatoxin in developing countries is mainly focused on good agricultural practices.

Because it is impossible to completely eliminate this danger, in the United States feeds and grains are laboratory tested for levels of aflatoxins and food with unacceptable levels are removed from the market.

“Although aflatoxin makes peanuts taste bitter, some unscrupulous food processors or peanut vendors simply mix these bad peanuts with the good ones rather than throw them out,” he said, stressing that mixing contaminated ingredients with unadulterated ones has been prohibited by the FDA Act of 2009, and the Consumer Act of the Philippines.

“All food manufacturers are hereby warned against processing aflatoxin-contaminated or adulterated raw ingredients into finished products,” the acting Director General said.

“All consumers are strongly advised to buy only FDA-registered prepackaged products.”
