Final answer:
Preserving foods in jars or cans with lids and hot wax creates a seal that prevents the entry of bacteria, molds, fungi, or yeast, reducing the risk of foodborne illnesses.
Step-by-step explanation:
Preserving foods in jars or cans with lids and hot wax helps to prevent foodborne illnesses by creating a seal that prevents the entry of bacteria, molds, fungi, or yeast.
The hot wax and lid create a barrier that protects the food from contamination during storage.
Additionally, the heat used in the preservation process helps to kill any existing bacteria or microorganisms that may be present in the food, further reducing the risk of foodborne illnesses.
