The latest research shows there is no evidence that pigmentation in wild pig skins is affected by any of the pesticides commonly used on farms and fields.
The findings suggest the use of chemicals, such as chlorpyrifos, in pig skin products may actually increase the risk of pigmentation problems, according to the research published Thursday in the journal Environmental Health Perspectives.
It’s a new development, said Dr. David McEwan, an assistant professor of dermatology and ophthalmology at the University of Alabama at Birmingham.
But the finding doesn’t mean there’s no risk, he said.
Pigs that have been sprayed with pesticides for at least five years can become sensitive to the chemicals, which are also known as insecticides, McEwaing said.
The risk of skin problems from the chemicals is higher in pigs exposed to higher levels of the chemicals.
“This finding shows there’s not really a direct correlation,” McEwen said.
“This is an issue that we need to look at more closely.”
Pig skin was once considered a natural color to be used by pig farmers and other animals because of its high pigmentation and strength.
But in the past few years, some scientists have questioned whether this natural pigmentation is being lost because of environmental toxins.
A team led by McEawan used a genetically modified pig skin to study the pigmented pigmentation, which was observed on skin samples of captive wild pig farms in Wisconsin and Indiana.
The pigs were raised on farm farms for about four years.
The research team was led by a professor of genetics at the UC Davis School of Veterinary Medicine, and was funded by the National Science Foundation.
McEwaings research team found the pig’s pigmentation was not affected in this study.
The team also tested pig skin for its chemical content, which indicates whether the pig skin was treated with any pesticides.
The team found there was no difference in the pigments of pig skin treated with chlorpryifos or any other pesticides in terms of their chemical content.
But there was a significant difference in pigmented skin treated by a combination of chlorporyifos and glyphosate, which has been linked to adverse health effects.
Glyphosate, also known by the brand name Roundup, has been used since the 1950s to control weeds, and is widely used on farm fields and in other areas.
A large number of studies have linked glyphosate to human health issues including cancer and birth defects.
“We didn’t see any change in the skin pigmentation when the farmers were treated with a combination,” McElwain said.
“The skin pigments in our study were unaffected by chlorpysulfonamides or other pesticides.
So this is a promising result, and it’s one of the first ones we’ve seen.”
But other research has suggested that the natural pigments may not be as strong as we thought.
A 2012 study in the Journal of Applied Toxicology suggested that glyphosate may be a neurotoxin.
“It’s not clear that the skin may be affected more than the pig, but it is possible that they might have more skin pigment than we thought,” McEllaing said in a statement.
“We’ll be looking at more of this in future studies.”
