Common Contamination
What are some common causes of foodborne illnesses ?
Food safety is a major concern for consumers, and there are several types of contaminants that can make food unsafe to eat. Bacterial contamination is the most common type, with Escherichia coli (E. coli), Listeria monocytogenes, Salmonella, Staphylococcus aureus, and Campylobacter jejuni being some of the most common bacteria that can cause foodborne illness. Viral contamination is also a concern, with norovirus, rotavirus, hepatitis A virus (HAV), and enteroviruses being some of the most common viruses that can cause foodborne illness. Parasitic contamination is less common but still a concern, with Giardia lamblia and Cryptosporidium parvum being two of the most common parasites that can cause foodborne illness. Chemical contamination is also a concern, with heavy metals, pesticides and herbicides, dioxins and PCBs being some of the most common chemicals that can contaminate food. Finally, there have been several outbreaks of foodborne illness in recent years, including outbreaks of E. coli O157:H7 in spinach in the United States in the late 1980s and early '90s, outbreaks of Listeria in deli meats in Canada in the late '90s and early '00s, and outbreaks of norovirus in cruise ships in recent years.
How can cross-contamination be prevented in a commercial kitchen ?
Cross-contamination is a significant concern in commercial kitchens, where food safety and quality are paramount.

What are some common electrical hazards ?
Electrical hazards are a common occurrence in homes, workplaces, and public areas. They can cause serious injuries or even death if not handled properly. Here are some of the most common electrical hazards: ## Overloaded Circuits An overloaded circuit occurs when too many appliances are plugged into a single outlet or circuit. This can cause the circuit to overheat, leading to a fire. It is important to distribute the load across multiple outlets and avoid using extension cords as permanent solutions. ## Faulty Wiring Faulty wiring is another common electrical hazard. This can occur due to poor installation, wear and tear, or damage to the wires. Faulty wiring can cause short circuits, sparks, and electrical shocks. Regular inspections and maintenance by a licensed electrician can help prevent this hazard. ## Water and Electricity Water and electricity do not mix. If water comes into contact with electrical devices or wiring, it can cause electrocution or electrical fires. It is important to keep electrical devices away from water sources and ensure that all electrical appliances are properly grounded. ## Ungrounded Outlets Ungrounded outlets lack a third prong that grounds the outlet to the earth. This can lead to electrical shocks and increase the risk of electrical fires. It is important to have all outlets in your home or workplace grounded for safety. ## Damaged Cords and Plugs Damaged cords and plugs are also common electrical hazards. If a cord is frayed or cracked, it can expose live wires and cause electrical shocks. Similarly, damaged plugs can cause sparks and short circuits. It is important to replace damaged cords and plugs immediately. ## Improper Use of Extension Cords Extension cords should only be used temporarily and never as a permanent solution for powering appliances. Overloading an extension cord can cause it to overheat and start a fire. It is important to use extension cords sparingly and ensure they are rated for the amount of power being drawn through them.
