PCBs in these eggs were four-fold higher than the EU standard and 171-fold more elevated than the standard for dioxins and dioxin-like PCBs.

An adult eating just one egg from a free-range chicken foraging in the Agbogbloshie scrap yard and slum would exceed the European Food Safety Authority (EFSA) tolerable daily intake (TDI) for chlorinated dioxins by 220-fold. The typical daily egg consumption per person in Ghana is less than one egg a day, but even eating 2.5 grams of an egg per day would exceed the EFSA TDI by more than 15-times. 

Weak controls allow the dangerous export of e-waste

Researchers from BAN have tracked shipments of used electronic devices from Europe to Ghana. The 2018 BAN report Holes in the Circular Economy: WEEE leakage from Europe revealed how e-waste from homes and businesses in Europe were fitted with electronic trackers and traced to developing countries. In Africa, the European e-waste was illegally dumped in Ghana along with locations in Nigeria and Tanzania.

Weak controls in international treaties allow developed countries to export e-waste to developing countries, leading to dangerous food chain contamination.
