You’ve probably noticed that the plastic food lidders that come in pet food boxes are always shiny and squeaky.

That’s because they are made with a high-density plastic coating that is made to withstand a wide range of weather conditions.

But a new study finds that this coating can cause a leaky lid that could lead to bacteria in your pet’s food.

Read moreIn a new report by researchers from Cornell University and the University of Texas Southwestern Medical Center, they report they found a number of bacterial outbreaks in pet foods that were produced in 2013, 2014 and 2015.

In one example, the researchers found that the lids of some pet food packages they analyzed leaked.

They were made from a high polyethylene plastic material that was designed to withstand the harsh winter climate and other harsh environments.

In addition, the material was also coated with an antibiotic that could damage the food’s microbial ecosystem.

“The food was manufactured under conditions where there was some microbial degradation in the liddings,” lead author Jessica Hern, a postdoctoral fellow in microbiology and molecular microbiology at Cornell University, said in a press release.

“We observed that this was caused by a bacterial degradation reaction.

We have shown that it is a possible cause of the leaky lids, but it could be caused by other conditions that could have caused the bacterial degradation.”

The team analyzed pet food labels in the study and found that, of the 2,732 pet food packets they tested, 466 contained the same type of bacterial degradation in their lids.

“It was very clear from this study that we have a high risk of food contamination from food lidding,” Hern told Healthline.

“We have to make sure that we’re not exposing our pets to these chemicals or any chemicals in the environment that could be toxic,” she said.

In an effort to reduce the risk of bacterial contamination, the team found that they were able to use a method called microbial filtration to eliminate any remaining bacteria in the food.

That process is similar to a filter that filters food that comes in the mail.

It is designed to remove bacteria that are not important to the food but that could cause problems in the process.

Hern said it’s important to note that the food manufacturers did not report the extent of bacterial growth in the pet food.

“The manufacturers didn’t have the data that we did, and we don’t have that data, so we don, as an industry, know how to be more aware of our food,” she explained.

“This is the first time that we’ve been able to look at this.

We want to make our pet food safer for the environment.”

The researchers say their findings could have an impact on the way pet food is sold.

The FDA does not require food manufacturers to report the bacteria in their food.
