Food at risk from toxic packaging, says new report

Supermarket food is at risk of being contaminated by a ‘highly toxic’ chemical found in the glue of packaging labels, according to a new study.
The chemical, which is in the same class of toxicity as mercury, asbestos and hydrochloric acid, can seep through and contaminate food, says the research, and is found in high levels on some of the sticky labels attached to packages of fresh meat, vegetables and tubs of sauce.
The study follows previous research that found chemicals in a wide range of products that may cause infertility in women, cancer, immune system disorders and neurological problems.
Strict EU safety regulations mean that certain materials can not come into direct contact with food, but there are no rules about the chemicals in label adhesives.
The study, published in the Royal Society of Chemistry’s Journal of Materials Chemistry, showed that toxic compounds on four label glues can seep through paper and plastic packaging and contaminate the food inside.
The researchers from the University of Zaragoza in Spain studied four different acrylic adhesives commonly used on food labels.
They examined in detail 11 compounds found in the glues, four of which seeped through the packaging.
Three of these had low toxicity while the remaining compound belonged to the highest risk category.
“This work brings significant breakthroughs in the study of compliance with regulations of food-contact materials,” says Valerie Guillard, an expert in food technology and packaging at the University of Montpellier, France.
