NORTH PLATTE, Neb. (AP) — Livestock producers are being warned to watch out for plastic, insulation and other debris in pastures and in feed from Sunday night’s tornado that hit North Platte.

Randy Saner is the extension agent for Lincoln and McPherson counties with the University of Nebraska. He says insulation and plastic are apparently spread across a wide area and can cause problems if eaten by cattle, sheep or goats.

Saner says fiberglass isn’t toxic, but it can block the digestive system.

Saner recommends picking up insulation and plastic found in fields and discarding hay and other feed heavily contaminated with tornado debris.

An EF3 tornado, with winds up to 165 mph, hit North Platte, injuring four people, damaging homes and vehicles and derailing railroad cars.

The weather service says the strongest damage in North Platte appears to be to homes along a city street on the west side and to power line trusses southwest of the city.

Another tornado was reported Sunday night in the northern Nebraska town of Valentine. No injuries or damage were reported.
