Penny, my granddog.A six-year study conducted at Tufts University’s Cummings School of Veterinary Medicine links lawn pesticides to canine malignant lymphoma (CML) with an increased risk for CML as much as 70 percent in dogs exposed to professionally applied pesticides and herbicides, or lawn care products containing insect growth regulators.

And another study published at the US National Library of Medicine National Institutes of Health shows the detection of herbicides in the urine of pet dogs following home lawn chemical application and indicating that exposure to herbicide-treated lawns has been associated with significantly higher bladder cancer risk in dogs.

In an article titled “The Seasonal Cancer Danger to Steer Your Dog Clear Of” Dr. Becker writes:

“In the study, urine samples were obtained from dogs in homes where herbicides were used, and from dogs in untreated homes. Chemicals were detected in the urine of dogs in 14 of 25 households before lawn treatment, in 19 of 25 households after lawn treatment, and in 4 of 8 untreated households. Researchers discovered the presence of herbicide in untreated lawns, leading them to conclude the chemicals can “drift” from treated to untreated properties. This means dogs can potentially be exposed in their own yard even if the yard is untreated, and from other properties if they travel from yard to yard.”

Encinitas bans Roundup weed killer in parks

The use of Roundup and other glyphosate-based, weed-killing products will no longer be allowed in Encinitas city parks starting next week.

Roundup is often referred to as the world’s most frequently used herbicide, both in agricultural areas and in residential yards. Publicity material from Monsanto, the multinational corporation that produces Roundup, states that when the product is applied correctly according to label directions, it “does not pose an unreasonable risk to human health, the environment or non-target animals and plants.”

Environmental health advocates disagree, contending that glyphosate has been linked to human health problems, including cancer and illnesses involving the central nervous system. Countries including Mexico, Russia and Netherlands recently have banned its use.
