Experts are warning that the condition of canned goods such as baked beans and tuna should be checked before consumption.
According to the UK’s Daily Mail on May 1, Paul Jackson, director at waste management company NRC, revealed that bacteria capable of causing paralysis and death might be hidden in canned foods like baked beans, tuna, and soup.
Jackson warned that if a dented or damaged can spurts liquid when opened, it could be a sign that it is contaminated with harmful bacteria.
He explained that rust on a can is a concern because it can weaken the metal and contaminate the contents. He added that even minor rust spots may indicate the food inside is no longer safe.
Jackson added that bulging is typically caused by gas buildup from bacterial activity inside the can, indicating that the food is spoiled and unsafe. He advised discarding bulging cans to reduce the risk of contamination.
While the bacteria itself is not harmful, storing it in sealed containers can cause a lack of oxygen, which can lead to the production of seriously toxic substances. Particularly, when the foodborne bacteria Clostridium botulinum proliferates, the neurotoxin it produces can lead to botulism, a condition that causes paralysis and requires caution.
Botulism symptoms include nausea, vomiting, stomach cramps, and constipation. Without quick treatment, it can cause respiratory paralysis and even death, with a mortality rate of 5-10%, which is higher than other foodborne illnesses.
To safely consume canned food, it is recommended to store it in a place with minimal temperature variation and low humidity.
Jackson advised keeping the cans in a cupboard far from the sink, where temperature changes rapidly and creates an environment where bacteria can easily thrive.
