Swiss farmers battle litterers to save herds

Plastic bags and aluminum cans tossed from cars can be picked up and shredded by harvesting machines, making it easy for cows to eat the shards — with sometimes fatal results

Before he mows the hay he feeds his dairy cows, Hansueli Wyss performs a new ritual: He scours the fields of his 26 hectare farm amid the rolling hills of Switzerland’s Solothurn farming region, dotted with steep-roofed homes like his 150-year-old farmhouse, for junk such as empty bottles, soda or beer cans, hamburger cartons and much else.

“It’s plastic bags, aluminum cans,” said Wyss, 50, who raised three children on the farm. “I make an effort to keep an eye on the cows, on the fields, but my machines shred this stuff in with the hay and the silage. That’s where the problem begins.”

Hard as it might be to believe, the orderly Swiss have a littering problem. Oddly enough, it is not in their towns and cities, where you might sooner stumble over a meteorite than a flattened soda can or empty cigarette pack.

However, out in the countryside southwest of Basel it is another story. So much litter is tossed out of cars that Swiss farmers have launched a campaign to fight it. They complain not just about the mess, but about the danger the refuse poses to livestock.

Litter can be fatal to ruminants. Four years ago, when one of Wyss’ cows died, he was convinced the cause was litter she ingested by accident.

“The problem is a cow’s stomach cannot always handle metal or glass,” he said.

Farmers or their veterinarians sometimes use magnets to draw out metal objects like screws or nails before they damage a cow’s stomach, but magnets are useless with shredded aluminum, he said.

The problem persists, he said, and the litter basket overflowed in July of last year when six cows of a neighboring farmer had to be slaughtered after ingesting something that caused fever and a sharp drop in their milk output.

“It was never proven scientifically, but the assumption was that it was the result of an aluminum can, or something similar,” said Urs Schneider, deputy director of the Swiss Farmers Union, in the capital, Bern, a half hour’s drive south of Solothurn. “There was enormous national attention, even lacking hard proof.”

Farmers hereabouts are convinced that aluminum cans, or even glass bottles, tossed onto a field are picked up by harvesting machines, shredded and mixed in with hay or silage. Once swallowed by the unsuspecting cows, the shreds can prove fatal.

“We get an awful lot of reports,” Schneider went on. “In the last four to five years, particularly along heavily trafficked roads, the problem has gotten continuously worse.”

After the slaughter of their neighbor’s six cows, farmers like Wyss, who keeps about 40 cows, a mixed breed of Simmental and red Holstein, demanded action.

A local farmers union, a branch of Schneider’s national association, hatched the idea for a campaign against litter in the countryside and the idea attracted followers everywhere.

“What was essential for me,” local branch secretary Peter Brugger said, “was the way the public reacted to the news of the cows’ slaughter, and now in all of Switzerland.”

He contacted two neighboring cantons, whose farmers immediately supported the idea for a campaign, which soon spread nationwide.

The idea of cows dying of litter hit a nerve.

Certainly, the Swiss cow does not enjoy the aura of sanctity of her Indian counterpart. Yet cows produce the cheeses, like Emmentaler and Gruyere, that are central to the Swiss way of life; cows dot the Swiss countryside as assuredly as do charming chalets and pointed church steeples.
