Rust in a baking pan can be unsightly and may impact the quality of your bakes, but can it make you ill? The consensus is that ingesting rust is not food-safe and should be avoided. However, the health consequences of ingesting small amounts of rust are considered minimal and unlikely to harm you. Nevertheless, rust may indicate that the non-stick coating of your pan has degraded, and particles of this coating may end up in your food, which could be harmful. Therefore, while a rusty pan may not make you ill, it is recommended that you replace it with a new one.

Rust is not food-safe and shouldn't be ingested
Rust, or iron oxide, is formed when iron is exposed to oxygen and water. While the health consequences of ingesting rust are said to be minimal, it is not a food-safe material and should not be ingested.
The presence of rust on your baking pans or cookware indicates that the rust-resistant coating has likely chipped or scratched, which means those particles may end up in your food. This is especially true for bakeware with non-stick coatings. The degradation of the coating will also compromise the non-stick power of the product.
Rust is also not very heat-conductive, so there will be areas in the bakeware that are not as hot as others during the baking process. This can negatively affect the flavour of your food.
If you notice rust on your baking pans, it is recommended to replace them with new ones. You can also try to remove the rust using various methods, such as scrubbing with a scouring pad, fine sandpaper, or steel wool, or by using a rust removal solution. However, it is important to note that some methods may damage the natural non-stick coating of your pan, so it is best to research the appropriate method for your specific type of pan.
To prevent rust from forming, it is crucial to properly care for your cookware. This includes washing and thoroughly drying your pans after each use, avoiding air-drying, and storing them in a dry place. You can also grease your pans with a thin layer of oil to protect the surface.

Breathing in high levels of iron oxide dust can cause lung issues
While the health consequences of ingesting rust are said to be minimal, it is still recommended that you clean or replace your rusty baking pan. Rust, or iron oxide, forms when iron is exposed to oxygen, and water speeds up this process. Therefore, to prevent rusting, it is important to thoroughly dry your pan after washing it.
The lungs are constantly exposed to danger from the dust we breathe. Luckily, the lungs have defence mechanisms that protect them by removing dust particles from the respiratory system. For example, the nose acts as an efficient filter, stopping most large particles. Some smaller particles may pass through the nose and reach the windpipe and the air tubes that lead to the lungs. These tubes are lined by cells that produce mucus, which catches most of the dust particles. Tiny hairs called cilia, covering the walls of the air tubes, then move the mucus upward and out into the throat, where it is coughed up and spat out or swallowed.
However, excessive inhalation of dust may result in disease. Inhalation of fine iron or rust dust over a number of years can lead to pulmonary siderosis, which is a form of pneumoconiosis. Pulmonary siderosis causes visible changes within the lungs, and any damage is permanent, although symptoms can be treated. People with pulmonary siderosis have experienced persistent breathlessness, coughing, and decreased lung function.
Therefore, it is important to take the necessary precautions to prevent exposure to iron oxide dust and to seek medical advice if you are experiencing any respiratory issues.

Rust on a baking pan may indicate that the rust-resistant coating has chipped off
Rust on a baking pan is not only unsightly but can also be a health hazard. While ingesting rust may not make you severely ill, it is still not recommended to cook with rusty pans. Rust is not a food-safe material and should not be ingested. When cooking with a rusted pan, there is a chance that some of the rust will end up in your food, which can add an unpleasant metallic flavour to your dish.
Bakeware is particularly prone to rust, and this is usually due to improper maintenance and general wear and tear. The presence of rust on a baking pan may indicate that the rust-resistant coating has chipped or scratched away, exposing the metal underneath to the elements. Metal reacts with air, water, salt, and acid, which can destroy the protective microscopic coating on the surface of the metal. This is why it is important to dry off your pans thoroughly after washing and to avoid leaving them to soak or air-dry.
If you notice rust on your baking pans, it is best to replace them with new ones. However, if you want to salvage your rusty pan, there are a few methods you can try to remove the rust. One method is to use sandpaper or a scouring pad to scrub off the rust, and then wash the pan with soap and water. You can also try using acidic products like vinegar or lemon juice to dissolve the rust. After removing the rust, it is important to season the pan again to prevent rust from forming in the future.
To prevent rust from forming on your baking pans, proper care and maintenance are essential. Always dry your pans thoroughly after washing and store them in a dry place. Avoid leaving your pans to soak or air-dry, as this can promote rust formation. Additionally, try to avoid using harsh detergents or scouring pads that can damage the natural non-stick coating of your pan. With proper care, you can help extend the life of your baking pans and avoid the potential health risks associated with ingesting rust.

The degradation of a pan's coating will compromise its non-stick power
The degradation of a pan's coating can also cause rust-resistant and non-stick particles to end up in your food. This is especially true for non-stick pans, where the degradation of the coating will compromise the non-stick power of the product. Therefore, it is recommended to replace pans with rust rather than continuing to use them.
If you want to remove rust from your pans, you can use acidic products such as vinegar or lemon juice to dissolve the rust. For pans with a non-stick coating, dilute the acidic solution with water so that the acid does not damage the pan. You can also use baking soda, scouring pads, fine sandpaper, or steel wool to scrub off the rust. After removing the rust, coat the pan with cooking oil to prevent rust from returning.
It is important to note that while the health consequences of ingesting rust are minimal, rust is not a food-safe material and should not be ingested. Therefore, it is recommended to clean or replace rusty pans, especially if the rust is difficult to remove or if the pan is non-stick.

Rust can be removed from a pan using acidic products such as vinegar or lemon juice
While the health consequences of ingesting rust are said to be minimal, it is still recommended to clean or replace a rusty pan. Rust, or iron oxide, can form when iron is exposed to oxygen. Water speeds up the rusting process, so it is important to thoroughly dry pans after washing. According to the CDC, breathing in high levels of iron oxide dust can cause lung issues.
For heavier rust, vinegar can be used. Fill your sink or a container with equal parts white vinegar and water, then soak the pan for an hour. After soaking, scrub the pan with a scouring pad or sponge. For extra cleaning power, sprinkle baking soda onto the rusty spots before adding the vinegar.
