Bacteria
There are several bacteria that can affect ham, but the most common are those of the genus Clostridium. These bacteria produce toxins that can cause a disease known as botulism.
Botulism is a serious illness that can cause muscle weakness, difficulty in speaking and swallowing, blurred vision and even paralysis. This disease can be fatal if not treated properly.
To prevent bacterial contamination of ham, it is important to follow proper food processing and storage practices. This includes maintaining proper hygiene in the kitchen, storing ham at the proper temperature and avoiding contact between raw and cooked foods.
It is also important to ensure that the ham you purchase is properly processed and has been inspected by the relevant health authorities.
