The FDA has warned of 10 pieces of cookware that may be leaching lead into food.

The Food and Drug Administration has identified more cookware that could be leaching lead into your food, it said in an expanded warning updated on Oct. 15.

The FDA published an initial notice on Aug. 13 and an update on Sept. 12 after testing pots made by an Indian manufacturer and finding that they were made with Hindalium/Hindolium or Indalium/Indolium, metal alloys that are made from aluminum, aluminum alloys and brass. These substances are common in some types of imported cookware, said the FDA, but are not used in the United States due to their tendency to leach lead into food cooked or stored within.

Since then, three more manufacturers/distributors and six more products were added to the list.

There is no known level of lead exposure that is considered safe and some people are at even higher risk of adverse effects, warned the agency, including young children, people of child-bearing age and people who are breastfeeding.

Here's what to know.

Which cookware is included in the warning?

The FDA originally identified issues with products from one manufacturer, an Indian aluminum cookware company called Saraswati Strips Pvt. Ltd, that sells products under the brand name Tiger White. In September, two more manufacturers and/or distributors were added to the list, including Indian companies Goyal Group Inc., selling under the brand name Silver Horse, and Grain Market LLC.

The October update added six new products from three new manufacturers and/or distributors:

New Reliance Traders Inc., selling products under the brand Royal Kitchen Cookware.

Win Chong Trading Corp., selling products under Town Food Service Equipment Co.

Indian Cookware & Appliance LLC, selling unbranded products.

Two other products were unbranded and identified only by the stores where they were sold.

The full list of affected cookware products as of October includes:

Tiger White brand Kadais/Karahis, or deep pots used for simmering and frying. The FDA tested two specific items at a Mannan Supermarket in Jamaica, New York, labeled "Pure Aluminium Utensils Tiger White RTM No: 2608606 An ISO 9001:2015 Certified Co. Saraswati Strips Pvt. Ltd. India."

Silver Horse brand "Aluminium Mathar Kadai 26," ID number 765542730845.

Silver Horse brand "Aluminium Milk Pan 4," ID number 765542728637. The FDA tested both Silver Horse products at a Patel Brothers market in Schaumburg, Illinois.

JK Vallabhdas brand "Aluminium Kadai India Bazaar #3," ID number 2000000772. The FDA tested the product at an Indiaco store in Hoffman Estates, Illinois.

Royal Kitchen Cookware brand "Milk Pan-size 3." The FDA tested pans sold at a Subzi Bazaar store in Rochelle Park, New Jersey.

Town Food Service Equipment Co. brand "3 qt Aluminum Saucepan."

Town Food Service Equipment Co. brand "2 qt Aluminum Saucepan." The FDA tested both Town Food products at a Best Kitchen Supply store in Washington, DC.

Dolphin Brand "Aluminum Saucepan." The FDA tested the saucepans at a DBA Diya Handicrafts store in Chicago.

Unbranded brass pots sold at a Santos Agency store in San Leandro, California.

Unbranded "Kadai/Karahi Aluminum Hammered Kadai Size 7" pans sold at an Indian Supermarket store in Sacramento, California.

The FDA warns that these are not the only potentially affected products and more could be added as the investigation continues.

What to do if you have an impacted product

Consumers should check their homes for any listed products or similar cookware and throw them away. They should not attempt to refurbish or repair the cookware.

If you are concerned about possible lead exposure, the FDA advises contacting your health care provider.

Retailers and distributors are responsible for ensuring the safety of cookware they sell, said the FDA, meaning those that may have the affected products on the market should use the FDA’s lead leach testing protocol for cookware or another testing method. They are also encouraged to consult with the FDA on the updated safety and regulatory status of food-related products.

What is the risk of lead exposure?

The FDA does not allow the use of lead in products related to food, including components of cookware and other food contact surfaces.

Lead is toxic to humans and can be ingested when a product like the cookware leaches it into items it comes into contact with. Even low levels of exposure are linked to serious health issues, including fatigue, headache, stomach pain, vomiting, or neurologic changes, according to the FDA.

Exposure is especially dangerous to developing fetuses and children, potentially causing learning difficulties, low IQ and behavioral changes. Even when they don't show obvious symptoms, babies and children can be permanently impacted by elevated levels of lead in their blood, especially due to their smaller size and metabolism.
