Arsenic-laced Chicken
Ask someone to name a poison and arsenic will be one of the first things to come to mind. Oddly enough, it is fed to chickens because it makes their blood vessels appear pinker and, therefore, fresher. On top of this, arsenic-laced chicken manure is commonly used to feed cows, spreading the substance to their meat as well.
Found in: Poultry and manure fed cows
Health Hazards: Cancer
Banned in: European Union

Why all the concern about the safety of using carrageenan in foods? Starting in the 1960s there have been research studies showing that if excessive doses of carrageenan are consumed in animal trials inflammation can be induced in the small intestine. Likewise, inappropriate methods of introducing the carrageenan into the animals, i.e. in the animals’ only source of drinking water, have induced an inflammatory response in the small intestine. However, there has never been a validated inflammatory response in humans over the seventy plus years carrageenan has been used in foods. The anecdotal “upset tummies” reported in blogs as coming from consuming a food containing carrageenan are hardly
reliable sources of information on the safety of carrageenan.
Inflammatory responses in animals only occur when carrageenan can cross the blood membrane barrier of the small intestine. This only occurs when the extreme feeding conditions mentioned above are employed. Normal feeding regimes induce no such response.
Over the last decade a group of molecular biologists at the University of Illinois at Chicago lead by Dr Joanne Tobacman have been exploring the in vitro interaction of carrageenan with various genes and conclude that carrageenan can cause inflammation in the gut via a binding mechanism involving TLR-4 receptors. This group also concluded that carrageenan degrades in the gut and the degraded carrageenan can permeate the membrane barrier. Recent studies refute both of these claims, and furthermore this recent research questions the validity using in vitro studies to mimic the in vivo events in the GI tract when a human consumes a food containing carrageenan.
The bottom line on the safety issue is that in spite of all the efforts to downgrade or question the safety of carrageenan, particularly by bloggers, carrageenan is a safe food ingredient in all of the major regulatory jurisdictions of the world.
