Biological hazards include microorganisms such as bacteria, viruses, yeasts, molds and parasites. Some of these are pathogens or may produce toxins. A pathogenic microorganism causes disease and can vary in the degree of severity. Examples of biological hazards include Salmonella, E. coliand Clostridium botulinum.
Chemical hazards vary in the aspect of production they are related to. Some potential chemical hazards could be prior to a processor receiving product, such as the improper use of pesticides or antimicrobial residues. Others could be chemicals used on processing equipment such as oils used on equipment or sanitizers. Furthermore, other potential chemical hazards may include substances that are safe or used in processing at certain levels but can cause illness or injury if consumed at too high of a concentration, such as sodium nitrite or antimicrobial solutions used in intervention steps. The HACCP team will need to evaluate in the hazard analysis the likelihood of the chemical to cause illness or injury. Generally, an operation’s Standard Operating Procedures will address the acceptable use of products which could become hazards if not properly handled and monitored.
Physical hazards include objects that are hard or sharp such as glass, metal, plastic, stones, pits, wood, or even bone. Physical hazards can lead to injuries such as choking, cuts, or broken teeth. Some foreign material in food products may not be a physical hazard but rather an undesirable foreign material such as hair, insects, or sand that are not likely to cause injuries.

· Physical hazards are conditions or situations that can cause the body physical harm or intense stress. Physical hazards can be both natural and human made elements.· Chemical hazards are substances that can cause harm or damage to the body, property or the environment. Chemical hazards can be both natural or human made origin.· Biological hazards are biological agents that can cause harm to the human body. Some biological agents can be viruses, parasites, bacteria, food, fungi, and foreign toxins.
