The most popular goat milk products, including coconut milk and powdered milk, contain a preservative known as ammonium hydroxide, which has been linked to liver and kidney problems, kidney problems and other adverse health effects.
The USDA is investigating whether the ingredient can cause health problems for consumers.
In the past, the USDA has approved ingredients to contain the preservative.
The agency said it was reviewing the ingredient’s safety for the purpose of deciding whether it could be used in goat milk and goat soap products, which are made by companies that make goat milk.
The ingredient is a preservatives used to help protect the skin and mucus membranes from bacteria and fungi that can cause skin irritation, such as from rashes, blisters and skin infections.
It is not found in all goat milk or goat soap.
The preservative can cause liver and blood problems for people who have eaten the product, and it can cause kidney and liver damage for those who consume it in large amounts.
Agency spokeswoman Heather Anderson said the agency has not yet reviewed the ingredient in goat and coconut milk.
She said the ingredient is in the final stages of testing.
