The Food and Drug Administration is proposing rules to make pet food and animal feed safer.

This decision is partially due to the deaths of nearly 600 dogs from eating pet jerky treats imported from China.

The FDA still cannot determine the cause of death.

The new proposed rules would require stores selling pet food and manufacturers to practice safe sanitation and follow food safety plans.

The rules also plan to improve human health, as food borne illnesses from pets can be spread to humans.

If stores fail to prove their food is safe to sell, the FDA can halt their shipments.

The FDA is taking comments for four months before its final ruling and will hold public meetings to explain changes.

It could cost the pet food industry roughly $130M annually to comply with the changes, but smaller businesses will have more time to comply.
