Study Notes

Food Safety - Chemical Contaminants

  • Reported food poisoning incidents are linked to toxic chemicals in food and beverages.
  • Melamine, commonly used in plastics, is a significant chemical contaminant.
  • Food contamination can occur due to carelessness or ignorance.
  • Food workers who lack chemical handling knowledge can create serious risks.

Chemical Contamination Sources

  • Raw foods like wild mushrooms, red kidney beans, and green potatoes may contain natural toxins that cooking may not eliminate.
  • Pesticides used on agricultural products can contaminate food.
  • Additives in animal feed and antibiotic residues can contaminate foods.
  • Cleaning chemicals are not always safe for use in food preparation.

Effects of Chemical Contamination

  • Chemical contamination can affect taste.
  • It can cause vomiting.
  • Internal organs (esophagus, stomach, intestines) can be damaged.
  • Cancer is a possible risk.
  • Chemicals can be lethal.

Naturally Occurring Food Toxins

  • Many foods naturally contain carbohydrates, protein, and vitamins.
  • Some foods contain toxins to protect from insects or animals.

Naturally Occurring Toxins Examples – More Detail

  • Ciguatoxin: Found in contaminated tropical reef fish. Affects the body with vomiting, diarrhea, and breathing trouble.
  • Scombrotoxin: Caused by ingesting red meat fish with improper temperature control; symptoms include dizziness, burning sensation, and peppery taste.
  • Shellfish toxin: Accumulates in certain contaminated shellfish becoming toxic to humans.

Other Toxins

  • Mycotoxins: Molds, yeasts, and mushrooms release these toxins, capable of causing foodborne illnesses.
  • Aflatoxin: A type of mycotoxin linked to cancer.
  • Amygdalin: Found in some fruits, converting into cyanide within the body, causing discomfort or illness.
  • Ipomeamarone: Sweet potato component, which can be toxic if ingested in large amounts.
  • Glycoalkaloids: Found in potatoes, leading to abdominal pain, vomiting, and other symptoms.
  • Lectins: Present in certain beans, potentially toxic in raw state.
  • Trypsin: A component of raw soybeans, affecting growth of certain animals.
  • Oxalic acid: Found in rhubarb and may cause digestive problems.
  • Furocoumarins: Chemical found in parsnips can cause stomach ache and skin reactions.
  • Cucurbitacin: Wild zucchini component, causing vomiting, stomach cramps, and diarrhea.

Physical Contaminants

  • Physical contaminants such as hair, fingernails, and plastic can accidentally get in the food.
  • Other foreign objects such as metal shavings; glass; or bones can be in food.
  • Such contaminants can result in foodborne illness and/or injuries.

Food Handling Practices

  • Proper food handling practices, training, and awareness are vital in preventing contamination.
  • Using different transportation methods for food and chemicals.
  • Safe storage and food handling equipment is emphasized.
  • Use appropriate utensils and cooking methods to prevent reactions with certain foods.

Occupational Health and Safety

  • Employers must provide a hazard-free environment.
  • Employees must follow safety rules and regulations.
  • Employees have a right to refuse unsafe work environments.
  • There's a focus on maintaining accurate records of incidents and training.

Workplace Safety Improvements

  • Identifying hazards and developing a safety plan.
  • Performing regular workplace inspections.
  • Training employees on safety procedures.
  • Open communication about safety procedures in the workplace.
  • Monitoring injury rates and workplace health indicators.
