The Food and Drugs Authority vs COA FS Brouhaha

“It’s like they are trying to collapse the company. The fact that two bags of the product was contaminated does not mean all the products in the market was not good for our consumers”… Prof. Samuel Ato Duncan, The Chief Executive Officer of COA Herbal Center said in an interview on April 22, 2020.

The above statement gives me goose pimples and sends shivers down my spine! It either depicts absolute ignorance or complete misunderstanding of the point the Food and Drugs Authority (FDA) is making. Now, if one capsule (not even a bag/container, just one capsule) shows microbial contamination, you will have to pull the batch off the shelves and if more than one batch is implicated, you will have to pull the entire product from the market. The FDA may even ask for everything to be pulled off the shelves even if one batch was implicated! This is normal practice for all regulatory organizations around the World.

Also, for Prof Samuel Ato Duncan to go testing samples from some bottles at a different lab (shouldn’t any such lab be accredited?) and use the resultant negative results to chastise the FDA is just not acceptable. Why do I say this? Test A may show negative results while Test B will be positive (e.g. growing microorganisms on agar plates vs using PCR based technique).

Secondly, the fact that bottle A shows positive microbial contaminants does not mean that bottle B will do the same (though they may come from the same batch). Also, being the defendant, he could deliberately have provided the lab with ‘good’ samples! This is not acceptable!

Microbial contamination can degrade products or, more concerning, can infect and injure patients. According to the US Pharmacopeia (USP), dietary supplement ingredients should be entirely devoid of Escherichia coli, Salmonella, Staphylococcus aureus, or Clostridium species!

These are some of the bugs identified in COA FS on the Ghanaian market. A strain of E coli, O157:H7 is very dangerous. This strain causes severe diarrhea leading to renal damage and other serious complications including death. We are talking about something that can kill!

Pharmaceutical product recalls occur on regular basis all around the World and there are stringent conditions for manufacturers to satisfy before such products are allowed on the market again. Let me give you a few examples from other parts of the World.

Not quite long ago, two dietary supplements, “Zero For Him” and “Arthri-D” were recalled for possible Salmonella contamination in the United States. No illnesses had been reported to date in connection with this issue.

Zero for Him is a supplement that is distributed through Amazon. The product had 150 capsules in a 400 cc Light Amber PETE bottle. Routine testing by the company discovered the potential for contamination found Salmonella bacteria in one bottle. The product was tested and re-tested and no more bacteria were found, but the supplement was recalled out of an abundance of caution. Distribution of the product was suspended while the US FDA and the company investigated the problem.

Arthri-D was recalled for the same issue. This product was distributed nationwide through mail order. It is in a 225 cc, white plastic HDPE bottle. Routine testing by the company revealed the presence of Salmonella bacteria in one bottle. Again, the product was tested and retested and no more bacteria were found, but the recall was issued to protect consumers. The company stopped distribution of the product while an investigation continued.

Dietary supplement contaminated with bacteria/fungi/mold/yeast have been linked to patient harm. Below are three examples -

A bone marrow transplant recipient began taking multiple oral naturopathic supplements and developed hepatic mucormycosis. Fungi, including Aspergillus, Rhizopus, and Mucor, were identified in four of 10 different supplements, but it was Mucor indicus from the patient’s liver aspirate that DNA sequencing found to be identical to one of the contaminated dietary supplements.

A 10-year-old girl developed appendicitis and liver abscesses from mucormycetes (Absidia corymbifera), which DNA sequencing identified from a probiotic she used.

A fatal case of gastrointestinal mucormycosis occurred in a premature neonate given a dietary supplement. DNA sequencing identified Rhizopus oryzae in a tissue sample that matched the dietary supplement.

I disagree with the argument that the FDA is being too harsh on the manufacturer of COA FS. Before you jump to their defense and say negative things about the FDA, please ask yourself if you will knowingly take a contaminated drug or give one to your child!

Also, those who argue that the product should not have been approved initially for sale are speaking from a point of ignorance of protocols/procedures.

Now, if one submits an application to register a product as a food supplement, there is no need for clinical trials. This is a standard registration procedure. Once the active ingredients are known (herbs listed), you get a market authorization after toxicity tests have been done to ascertain safety profiles. These were all done and the product passed! The fact that a product has passed such tests does not mean the FDA is done with their job. They have a responsibility to monitor every product on the market. Postmarketing surveillance (PMS) (also post market surveillance) is the practice of monitoring the safety of a pharmaceutical drug or medical device after it has been released on the market and is an important part of the science of pharmacovigilance.

It was during one of such monitoring episodes that the FDA detected microorganisms in more than one batch of the product and immediately notified him to recall the product. Unfortunately, he didn't comply and resorted to an outmoded strategy of pitching the public against the FDA.

Microbial contamination of pharmaceutical products is a common problem which has been reported and dealt with professionally. Contamination of Pharmaceuticals with micro-organisms can bring about changes in their physical characteristics, including the breaking of emulsions, the thinning of creams, fermentation of syrups, and appearance of turbidity or deposit, besides producing possible off odors and color changes.

These changes will not only make the product aesthetically unacceptable but can also affect the therapeutic potency and dosage delivery. The presence of microbial contaminants in pharmaceutical products has also proved to be a potential health hazard to the consumer. The extent of the hazard will vary from product to product and patient to patient, depending on the types and numbers of organisms present, the route of administration, and the resistance of the patient to infection (immunocompromised patients/clients). The majority of contaminants of pharmaceutical products and ingredients are bacteria, yeast and filamentous fungi (mould).

The FDA has a Safety Monitoring Department that derived their mandate to ensure the safety of regulated products from the Public Health Act, 2012, Act 851, Part 7, Section 125. The Department is mandated to continually monitor the safety of the products regulated under the Public Health Act 851 by analysis of the adverse effect or event reports and by any other means and take appropriate regulatory action when necessary.

Science may not have all the answers to our questions or problems, but we need to allow our institutions to work. The FDA has a mandate to protect the public, and we should allow and support them to do their job! Let us take a step back and leave out the emotional stuff and let the FDA do what is required of them!

Please ask yourself if you will knowingly take a contaminated drug or give one to your child, parents or a loved one? At the end of the day, drug recalls are in the interest of public health and safety!

Disclaimer – I have NO interest in the Ghana FDA and do not import/manufacture any product that competes with COA FS.
