Food Safety and Regulatory Compliance of Sachet Alcoholic Beverages: Evidence from Heavy Metals, Labelling and Alcohol Content Discrepancies

In many parts of Sub-Saharan Africa, a specific type of drink has become a staple of daily life. These are alcoholic beverages sold in small, flexible plastic pouches, often called sachets. They are cheap, easy to carry, and available in nearly every corner store. Because they are so accessible, people from all walks of life, including young adults and commercial drivers, consume them regularly. However, the way these drinks are made is often unregulated. Unlike mass-produced bottled drinks that undergo strict factory checks, sachet alcohol is frequently produced in small batches where the ingredients and equipment are not closely monitored. This lack of oversight raises a serious question: what is actually inside these pouches? While the label might promise a certain strength of alcohol, the liquid inside could contain harmful substances like heavy metals—dense, toxic elements such as lead or iron that can damage the body over time—or it might simply be a much weaker drink than advertised. Understanding the true contents of these popular drinks is vital for public health, as millions of people rely on them without knowing the potential risks they face.

A team of researchers set out to investigate the safety and accuracy of these sachet alcoholic beverages in Abeokuta, Nigeria. They focused on three critical areas: the presence of dangerous heavy metals, the actual amount of alcohol in the drink compared to what the label claims, and whether the packaging followed official government rules. To do this, they purchased fifteen different brands of these sachet drinks from local markets. The selection included popular varieties like gin, schnapps, bitters, and rum. Once in the laboratory, the scientists broke down the liquid samples to look for specific chemical elements. They used a highly sensitive machine that can detect tiny traces of metals, checking for six essential trace elements and eight toxic heavy metals. They also measured the exact amount of alcohol in each sample and compared it to the percentage printed on the front of the sachet. Finally, they examined the labels to see if the manufacturers had included all the required safety information, such as registration numbers and warnings.

The results revealed a troubling picture of inconsistency and potential danger. When the team measured the actual alcohol content, they found a massive gap between what was on the label and what was in the bottle. The labels claimed the drinks contained an average of 37.35 percent alcohol, but the laboratory tests showed the real average was only 13.35 percent. In many cases, the difference was extreme. One brand of bitters claimed to be 35 percent alcohol but tested at just 0.1 percent, which is barely any alcohol at all. Another brand of gin claimed 43 percent but contained only 21.8 percent. This means that consumers are often misled into thinking they are drinking a much stronger product than they actually are. Conversely, one brand of schnapps was slightly stronger than advertised, but the overwhelming trend was that the labels lied about the strength, usually by a large margin.

Beyond the alcohol content, the study found evidence of contamination that could harm human health. While the researchers did not find any of the most dangerous toxic metals like lead, mercury, or arsenic in the samples, they did find high levels of iron in several brands. Iron is a metal the body needs, but too much of it can cause serious health problems. Two of the brands tested contained iron levels that exceeded the safety limits set by the World Health Organization. One brand had 519 micrograms of iron per liter, and another had 395 micrograms, both surpassing the safe limit of 300 micrograms. This suggests that the equipment used to make these drinks, or the water used as an ingredient, might be contaminated. The presence of these metals indicates that the production process lacks the quality control found in regulated factories.

The investigation also uncovered significant failures in how the products were labeled and regulated. Although every brand displayed a government registration number, only a small fraction of them were actually valid. When the researchers checked the official government database, they found that many of the numbers on the sachets were expired or did not exist at all. Furthermore, nearly half of the brands made false health claims on their labels. They advertised that their drinks could cure diseases like malaria or back pain, or improve sexual health, which is strictly forbidden for alcoholic beverages. Some labels also failed to list all the ingredients or did not include the mandatory warning that the drink is not for people under eighteen years old.

These findings highlight a system where the safety of the consumer is not being protected. The drinks are being sold with inaccurate information about their strength, potentially leading people to drink more than they intend in an attempt to feel the effects they expect. At the same time, the presence of excess iron and the lack of valid registration numbers suggest that the production environment is unsafe and unmonitored. The researchers concluded that the current regulations are not being enforced effectively. They argue that authorities need to step in to ensure that these beverages are made safely, that the labels tell the truth about what is inside, and that the products are actually registered with the government. Without these changes, the people who rely on these affordable drinks remain at risk of both alcohol-related harm and exposure to toxic metals.
