Final answer:
No, the bitter taste and surface mold are not signs of botulism infection in foods. Proper sterilization and canning procedures have reduced the incidence of botulism.
Step-by-step explanation:
No, the statement is not true. Bitter taste and surface mold are not necessarily signs of botulism infection in foods. Botulism is caused by the toxin produced by the bacterium Clostridium botulinum, which can grow in anaerobic environments like improperly processed canned foods or homemade preserves. While it is important to discard foods with surface mold, this is due to the risk of other types of foodborne illnesses, not specifically botulism.
In the past, botulism was more common due to improper sterilization and canning procedures, which allowed the bacterium to thrive. However, with better sterilization and canning practices, the incidence of botulism has reduced significantly.
If you suspect that a certain food item may be contaminated with botulism, it is best to err on the side of caution and dispose of it. Signs of botulism infection include bulging or leaking cans, swollen containers, or abnormal smells or tastes in preserved foods.
