As Arsenal will probably find out this evening against Barcelona, sometimes you just can’t win.

Food companies and the mults are usually first in the firing line from environmental campaigners when it comes to packaging. And when Del Monte starts wrapping individual bananas, you can kind of understand why.

But much of the criticism ignores the great strides being made by the industry to lessen its environmental impact – as well as the simple commercial reality that you don’t spend millions unnecessarily forcing expensive packaging on consumers that don’t demand it.

Today boffins in Switzerland are reporting that while recycled cardboard might be kinder to Mother Earth than pulping the rainforest, it’s not so good for people eating cereal packaged in recycled boxes.

They say ink from newspapers that are recycled into cardboard contains mineral oils that can then leach into foodstuffs boxed in the card. In sufficient quantities, the oils could prove carcinogenic.

Before you start choking on your afternoon bowl of cornflakes, it’s only long-term exposure that presents a risk. But the findings emphasise the Catch-22 situation for manufacturers caught in an ethical crossfire between health campaigners and the green lobby.

Jordans has “reluctantly” stopped using recycled card, while Kellogg’s is now “looking at [its] packaging” in response to the problem.

It gives an unfortunate extra dimension to the saying about today’s news becoming tomorrow’s fish and chips wrappers.
