Do you know the expression “Open the Pandora’s Box“? The phrase came from a myth and expresses that mischief takes place, as the saying goes, ” when you open the box”.
Today you could say you should not open a tin can.
Bisphenol A, or BPA for short, is one of the most widely used (millions of tons) of industrial chemicals in the world. The fact that the hormone bisphenol A is contained in many everyday products is well known, but it can be found, as samples showed, even in canned foods.
Bisphenol A in canned foods
BPA is used for the production of epoxy resins. These plastics are often lined with cans to prevent corrosion.
Various investigations wanted to determine how much BPA from these coatings goes from the inner side of the can to food.
Cans of fish, vegetables (especially tomatoes), corn, sauerkraut and coconut milk were examined with a frightening result.
About 74 percent of the food samples tested were contaminated!
The harmful substance BPA has been detected in the often purchased cans of large retail chains in 5 out of 7 canned tuna. In four of 7 canned tomatoes and 3 of 5 cans of coconut milk. The lowest value was 7.4 the highest 510 micrograms per kilogram. The tomato and tuna concentrations were between 9 and 28.5 micrograms per kilogram.
Various influences such as Storage temperature, heating, fat content, acidity can influence the migration behavior of BPA. It can come to different concentrations and it is therefore difficult to calculate how much BPA is in a can.
At the same time as the federal investigation, Global 2000 investigations were carried out, with a similar outcome. In these studies, a value of 318 micrograms per kilo of coconut milk was found. Tuna found a weert of 140 micrograms
Parallel investigations of Global 2000 led to similar results: here too the highest value of 318 micrograms per kilogram was found in a coconut milk preserve,
It is reported that health damage caused by consumption of a contaminated can is not to be feared. However, the risk increases with frequent consumption of preserved foods.
As informed by the European Food Safety Authority (EFSA), the consumer first and foremost takes up BPA through canned food. The burden of other BPA-containing products as is to be considered. Thermal paper (Kassabons), various adhesives u.a. these include. In addition, the burden of other BPA-containing products, such as thermal paper (receipts), adhesives, div. Dishes.
The effects of BPA (similar to the hormone estrogen) have been reported in all media.
A ban on the hormone drug BPA in the EU is required. Not only politicians but also manufacturers should take responsibility.
