Jar lids raised as a cancer concern

LONDON — Europe’s food safety agency recommended Wednesday that baby food manufacturers change the lids on their jars as soon as possible because of cancer concerns regarding a chemical found in some food packed in bottles and jars.

However, the European Food Safety Authority said there was no need for parents to stop using infant food because any cancer risk was extremely low and the jars have an excellent safety record for germs and other contaminants.

The chemical, semicarbazide, has been found in very small quantities in certain foods packaged in jars with metal lids incorporating plastic vacuum seals, a type of packaging used worldwide for more than 20 years.

Semicarbazide, or SEM, belongs to a family of chemicals known to cause cancer in animals. One study has shown it can cause tumors in mice. No human studies have been conducted. The European Food Safety Authority is the first organization to have taken a close look at the risks posed by the chemical.

Scientists investigating on behalf of the European food agency concluded the danger is very slight.

"The risk to consumers resulting from the possible presence of semicarbazide in foods, if any, is judged to be very small, not only for adults but also for infants," said Dr. Sue Barlow, chair of the European Food Safety Authority expert panel.

"Nevertheless," the agency said in a statement, "experts believe it would be prudent to reduce the presence of semicarbazide in baby foods as swiftly as technological progress allows."

The agency also recommended the industry change the lids for other products, after baby foods have been tackled.

Besides baby food, bottled foods found to have traces of semicarbazide included fruit juices, jams, sterilized vegetables, pickles, mayonnaise, mustard, sauces and ketchup. However, baby food had by far the strongest concentrations, probably because the contact between the food and the seal is more significant — the jars are small, but the cap still has to be big enough to fit a spoon in.

American manufacturer Heinz, which makes baby food and other products in jars, said it is already testing alternative caps and hopes to have new jars — free of the chemical — on supermarket shelves worldwide within six months.

The U.S. Food and Drug Administration said consumers should not avoid food packaged in glass jars.
