Can you Get Cancer from Leather Handbags and Shoes? Allergies from Jewellery? – The German Federal Office of Consumer Protection and Food Safety (Bundesamt für Verbraucherschutz und Lebensmittelsicherheit or BVL) has identified Excessive Chromium 6 and Nickel Levels in items made from leather and some pieces jewellery.

The German Federal Office of Consumer Protection and Food Safety (BVL) addresses the management of risks and coordinates monitoring for the Federal States (Bundesländer) of tobacco products, cosmetics and other goods which either come directly into contact with people or with food intended for human consumption. Under the heading of goods they include leather articles like handbags, shoes and gloves as well as jewellery and items used in body piercings.
Since 2014 the BVL has been investigating the levels of the carcinogen Chromium 6 in leather products and the amounts of allergen Nickel being taken up by the human body from jewellery and body piercing products. These are risk areas considered by the BVL to be of particular concern to human heath due to the linkage of chromium 6 with cancer and the potential for nickel to elicit serious contact allergies. I explained more about allergic contact dermatitis and its various causes in my recent article on this subject which described how I became an unwilling guinea pig to an allergy caused by laundry additives.

Allergenic Nickel in Jewellery and Clothing Accessories
The BVL published its latest research results in a German report on the 23rd November 2015. The report presented the findings of its investigation into whether products were exceeding the permitted maximum levels of Nickel which can be absorbed into the human body. It highlighted that jewellery articles on sale in Germany continue to exceed the permitted levels of this serious allergen. Nickel causes contact allergies when the nickel ion enters the human body – the potential to enter the body increases when the item containing the nickel is frequently or constantly being worn like a ring, an ear ring or other piercing item.
Highlights from the BVL study of nickel uptake from jewellery/accessories:
- 556 Samples were tested
- 17.4 percent of the earrings and other piercings tested exceeded the permitted maximum limits (Nickel uptake of 0,35 µg/cm²/week)
- 4.9 percent of jewellery, fasteners, accessories exceeded the permitted limits (0,88 µg/cm²/week)
- There had been no improvement in results since an earlier study in 2008
The results indicated that it is not simply the cheapest fashion items that lead to a serious risk of an allergic reaction. An item made from 18-carat white gold for example can contain 20% nickel as an alloy. Such items of jewellery or wrist watch casings can cause allergic skin contact reactions in about 1 in 8 people. The problem with nickel is made worse if the body’s immune system is sensitized to the metal through pronounced exposure. Once sensitized even a low level exposure can lead to a severe allergic reaction. Some samples tested by the BVG had levels of nickel which were 10 times the permitted maximum level.
Cancer Causing and Allergenic Chromium 6 in Leather
The investigation by the DVG also uncovered continuing high levels of another nasty contaminant – chromium 6 (or hexavalent chromium) – in leather products. They summarised their results as follows:
- 386 Samples were tested
- 16 Percent had chromium 6 concentrations exceeding the maximum permitted limit (3 mg/kg)
- Main culprits were leather gloves (33% exceeded) , bags (25%), work clothes (23%) and footwear (13%)
- 12 percent of samples of products produced in Germany exceeded the permitted level. For products produced in China this increased to 33%.
In addition to causing allergic reactions chromium has also been identified as a carcinogen. The form of chromium investigated by the BVG is the highly dangerous 6 or hexavalent form of the chemical. Some forms of chromium used in processing leather are relatively harmless but even these can be converted to the 6 form if appropriate precautions are not taken during the tanning process. In addition to causing severe skin contact allergies chromium 6 in high concentrations is a very toxic chemical and known genotoxic carcinogen. In leather chromium 6 compounds are sometimes used to produce a red or pink colouration.
These days we purchase many of our fashion items on-line and sometimes the origins of such goods are unclear. In addition, imported goods may not follow the strict product content requirements demanded by our local legislation. One way we can try to use our consumer power to reduce these risks is to require suppliers to confirm in writing that their goods fully conform with local laws and regulations concerning levels of chromium 6 (for leather) and nickel (jewellery, clasps, piercings, buttons, wrist watch cases). Good luck!

Chris Duggleby started his scientific career studying Bacteriology, Virology and Immunology at the Manchester University Medical School. From there he went on to spend over 35 in the chemicals and oil industries which included setting up a polymers research and development group in Geneva, Switzerland for a major international chemicals company. Following an MBA from Warwick University he went on to lead a number of international manufacturing and marketing operations in the Chemicals, Plastics and Oil industries. His work involved living and working in Europe, Asia, the USA, the Middle East, and Russia. More recently he was invited to take on a senior leadership position in the Audit Department of the BP International Oil Group. Here he used his global change and risk management experience to help the group reshape its management structures and processes following a major environmental disaster in the Gulf of Mexico. He has now retired to focus on writing about risk management and producing music in his studios near London, in the Alps and Cape Town.
