A recent study has uncovered a surprising fact about organic coffee. It seems that even organic coffee samples can contain traces of AMPA, which is a residue of glyphosate. This is unexpected because glyphosate is banned for use in organic farming practices. The research indicates that the levels of these residues can vary. Several factors influence the amount of AMPA found in coffee. These include how the coffee beans are roasted, the type of packaging used, and where the coffee beans originated from.
The study found that coffee beans from Africa tend to be cleaner, meaning they had lower levels of AMPA. In contrast, coffee beans from Hawaii showed higher levels of these residues. This suggests that farming methods and environmental factors in different regions play a significant role in the presence of glyphosate residues. For consumers who are concerned about reducing their exposure to these chemicals, this information is valuable. It suggests that when choosing coffee, it might be wise to consider the roast level, the packaging material, and the geographical origin of the beans.
While the study highlights potential issues with some organic coffee, it’s important to remember that organic farming aims to minimise the use of synthetic pesticides and herbicides like glyphosate. The presence of residues could be due to various reasons, such as environmental contamination from nearby conventional farms or cross-contamination during transport and processing. The research team noted that the roasting process itself might affect the levels of AMPA. Darker roasts, for instance, might potentially reduce the amount of these residues compared to lighter roasts, though more research is needed to confirm this.
Packaging also appears to be a factor. Some packaging materials might be more prone to leaching or absorbing contaminants than others. The origin of the beans is also a key indicator, as regional farming regulations and practices can differ. Coffee drinkers seeking to minimise exposure might prefer beans from regions with stricter regulations on pesticide use and better environmental controls. Understanding these nuances can help consumers make more informed choices about the coffee they purchase and consume. The findings encourage a closer look at the entire coffee supply chain, from the farm to the cup, to ensure the highest quality and safety for consumers.
