What You'll Learn
Ingesting rust is unlikely to harm you, but large amounts can be dangerous
Cooking in a rusty pot is generally considered unsafe and not recommended. While ingesting small amounts of rust is unlikely to harm your health, it is important to note that consuming large quantities can be dangerous.
The primary concern with ingesting rust is the potential presence of bacteria, particularly if the rusty cookware has been left outside and exposed to the elements. The bacteria that cause tetanus, for example, can collect on rusty items. However, unless your rusty cookware has been left outside, it is unlikely to harbour this bacteria.
Additionally, the U.S. Environmental Protection Agency (EPA) states that ingesting small amounts of rust will not harm your health unless you have a rare disease called hemochromatosis, which causes the body to retain iron. Similarly, the United States Department of Agriculture (USDA) and the United States Food and Drug Administration (FDA) have stated that ingesting small amounts of iron oxide (rust) is safe and can even provide health benefits, such as preventing anemia and addressing iron deficiency.
However, it is important to note that consuming large amounts of iron can lead to iron toxicity. This risk is particularly relevant for individuals with hemochromatosis, as their bodies are unable to regulate iron absorption effectively. Therefore, while ingesting small amounts of rust from a rusty pot is unlikely to cause harm, it is essential to address and remove the rust to prevent accidental ingestion of large quantities.
Furthermore, cooking in a rusty pot can negatively impact the flavour of your food, as rust can impart an unpleasant metallic taste. Additionally, the lack of seasoning on a rusty pot can cause food to stick, making cooking more difficult.

Rusty pots may negatively affect the flavour of your food
While it is unlikely that ingesting rust from a rusty pot will harm your health, it may negatively affect the flavour of your food. According to the United States Department of Agriculture, rust is not food-safe and should not be ingested. When cooking in a rusty pot, there is a chance that some of the rust will end up in your food, adding an unpleasant, metallic flavour. Food may also be more likely to stick to the rusty parts of the pot.
Some people claim that cooking in a rusty pot can add iron to your diet, which can help prevent anaemia. However, it is important to note that consuming too much iron can be dangerous. The FDA suggests an iron intake of 8 mg/day for men and 18 mg/day for women, while iron toxicity occurs at about 45 mg/day. Additionally, there is a rare disease called hemochromatosis, or haemochromatosis, in which iron accumulates in the body. Therefore, it is best to avoid cooking in rusty pots, as it may negatively affect the flavour of your food and potentially cause health complications for certain individuals.

Rust can make using your pot more difficult
While cooking in a rusty pot may not hurt you, it can make using your pot more difficult. Firstly, rust can cause food to stick to the pan, making it harder to cook and clean up afterward. For example, flipping pancakes or searing steak may become a frustrating task. Additionally, rust can negatively affect the flavor of your food, adding an unpleasant metallic taste. Even if you cannot taste the rust, it is still not ideal to ingest it. While small amounts of ingested rust are unlikely to harm your health, it is still not recommended to cook with rusty cookware.
Furthermore, if you are particularly sensitive to rust or have a rare disease like hemochromatosis or haemochromatosis, ingesting even small amounts of rust can cause health complications. Hemochromatosis causes the internal organs to retain iron, leading to iron accumulation in the body. While it is true that a little extra iron in your diet from cooking with a rusty pot can help prevent anemia, it is important to be cautious. Ingesting too much iron in the form of dietary supplements can be dangerous. Therefore, it is best to avoid cooking with rusty pots and use safe and effective rust removal products instead to keep your cookware in good condition.
Although it may seem wasteful to discard a rusty pot, it is essential to consider the potential health risks and the impact on your cooking experience. Rusty pots can make cooking and cleaning more challenging, affect the taste of your food, and potentially cause health issues for sensitive individuals or those with specific medical conditions. By investing in rust removal products or purchasing new cookware, you can ensure a safer and more enjoyable cooking experience.
While it is generally not recommended to cook in a rusty pot due to the potential impact on taste and the increased difficulty in cooking and cleaning, it is essential to note that the presence of rust may indicate a more significant issue. Rust often develops when there is no layer of seasoning on the surface of the pot, which can lead to food sticking and an unpleasant cooking experience. Therefore, it is crucial to address the underlying cause of the rust and take preventive measures to avoid further rust development. This may involve properly seasoning the pot, ensuring it is thoroughly cleaned and dried after each use, and storing it in a dry environment.
In conclusion, while cooking in a rusty pot may not cause immediate harm, it can negatively impact your cooking experience and, in some cases, pose potential health risks. To ensure the best results in the kitchen and maintain the longevity of your cookware, it is advisable to address the rust issue and create a safe and functional cooking environment.

Tetanus-causing bacteria may be present on rusty items
Rusty items are often associated with tetanus, a nervous system infection caused by bacteria that collect on items like nails or scrap metal left outside and exposed to the elements. While it is unlikely that rusty cookware will contain tetanus-causing bacteria unless it has been left outside, ingesting even small quantities of rust can cause health complications for those who are particularly sensitive.
The U.S. Environmental Protection Agency (EPA) asserts that ingesting rust in small amounts is generally not harmful to one's health, unless one has hemochromatosis, a rare disease that causes the body's internal organs to retain iron. Similarly, the FDA-approved food colouring, iron oxide, is safe for consumption in small quantities, as the average person is likely iron deficient. However, it is important to note that ingesting large amounts of rust can lead to iron toxicity, and inhaling large amounts of rust can cause respiratory issues.
While cooking in a rusty pot may not pose a significant health risk for most people, it can negatively affect the flavour of the food. Rust can add an unpleasant metallic taste and make food more likely to stick to the pan, impacting the cooking process and the overall taste experience. Therefore, it is recommended to remove rust from cookware and prevent its development through proper care and maintenance.
To remove rust, one can use steel wool or an abrasive scrubber with vinegar, lemon juice and salt, or baking soda and a potato. Thoroughly scrub the rusty areas, rinse with warm water, and repeat if necessary. Ensure the cookware is completely dry before applying a thin coat of oil and baking at a high temperature to create a protective, non-stick layer.

People with hemochromatosis should avoid rusty pots
Cooking in a rusty pot can have adverse health effects on people with hemochromatosis, a rare disease that causes the body to absorb too much iron. While ingesting small amounts of rust may not be harmful to most people, it can lead to serious health issues for those with this condition.
Hemochromatosis causes internal organs to retain iron, leading to a buildup of iron in the blood. This buildup can result in iron overload, causing gastrointestinal issues such as nausea and vomiting, and potentially more serious health complications over time. Therefore, it is crucial for individuals with hemochromatosis to avoid ingesting additional iron from external sources, including rusty cookware.
Rust is composed primarily of iron oxide, which can leech into food during the cooking process. While iron is an essential mineral, the form present in rusty cookware differs from dietary iron and can cause irritation to the stomach lining, even in small amounts. For individuals with hemochromatosis, this can further contribute to the excessive iron levels in their bodies.
Additionally, cooking with rusty pots can negatively affect the taste of food and compromise the integrity of the pot, leading to potential contamination. The rust may also increase the iron content of the food, as seen in studies where food cooked in cast iron pots showed a significant increase in iron content.
To maintain optimal health, individuals with hemochromatosis should avoid using rusty pots and pans for cooking. Instead, they should opt for ceramic or glass cookware, which are recommended by The Iron Disorders Institute. Proper maintenance of cookware, such as thorough drying and storage in a dry place, can also help prevent rust formation.
