1 LEARNING‘S FROM FOOD SAFETY OUTBREAKS (A Consumer Perspective) Dr. Sitaram Dixit Chairman, CGSI Toll Free Complaint Number

2 WHAT IS FOOD SAFETY OUTBREAKS? Food borne illness - Commonly called food poisoning. Causes : Food or beverages contaminated with bacteria, viruses, parasites, or moulds. Pathogens or harmful microbes produce toxins / poisons. High Risk : babies, children, seniors, pregnant women, sick people, people with less resistance to illness (transplant and cancer patients, AIDS, etc.)

3 Symptoms : Diarrhea, vomiting, nausea, stomach cramps, headache, fever, etc. Duration : Days, weeks, months, etc. Outcome : mild illness, serious illness, hospitalization, even death. Contaminated food: May look, taste & smell normal. Indications : Most times symptoms do not develop immediately on consumption of food but only after some time.

4 E.coli, infection can take days to develop illness. Salmonella can take hours for symptoms. Small number of microbes sufficient to cause infection e.g., Shigella, infection and E.coli, infection. Spreading : contact, touching an animal, swimming or wading in recreation pool or dirty contaminated water. When 2 or more people have symptoms of food borne illness after eating same food it is called outbreak. Over 100 affected persons is a large outbreak.

5 Causes of food borne illness Microbes (germs) : Tiny organisms, we cannot see but live around us in plants, animals, air, soil, water, etc. Good microbes : Yogurt / Dahi, Lassi, Idli, Dokla, etc. Pathogenic microbes : Parasites, moulds, viruses, and bacteria cause harm and illness. Microbes need time and right conditions to increase in number, produce toxins or poisons to cause illness.

6 Parasites Microbes that live on or in other organisms. They do not grow on food. Giardia and Cryptosporidium, found in untreated water. Parasites are destroyed by heating and freezing. Some parasites we can see, e.g., insects & worms, roundworm, tapeworm, etc.

7 Parasites - Control Boil water to make it safe for drinking. Wash hands after using toilet. Wash hands before preparing and eating food. Cook food to safe temperatures. Use safe water supplies.

8 Wash all fresh fruits and vegetables before consuming. Check and make sure that fresh fruits and vegetables you buy are not bruised or damaged. Check that fresh cut fruits and vegetables like packaged salads and precut melons are refrigerated at the store before buying. Do not buy fresh cut items that are not refrigerated.

9 Moulds Moulds spoil food, some produce toxins / poisons. Good mould is used in cheese making, Mushrooms. Moulds grow on warm, moist, and places with good supply of air. In acidic food like oranges, tomatoes, and sugary foods like jams, etc. Avoid cross contamination.

10 Viruses - Control Wash hands after using toilet. Wash hands before preparing and eating food. Cook food to safe temperatures. Use safe water supplies. Wash all fresh fruits and vegetables before consuming.

11 Bacteria Found everywhere in our environment. Most bacteria’s are harmless. Some are useful. Some and harmful and cause food borne illness. Pathogens are found in human and animal waste, soil, raw meat, poultry and fish.

12 Food borne illness bacteria Campylobacter Clostridium botulinum (Botulism) Clostridium perifringens E.coli Listeria monocytogenes Salmonella Shingella Staphylococcus aureus (Staph)

13 CONTAMINATED WATER Bacillus cereusNausea, vomiting, abdominal pain, diarrhoea Staphylococcus aureus, Entero-toxins-A,B,C,D or E Increased salivation, vomiting, abdominal cramp, diarrhoea, severe thirst, cold sweats, prostration Clostridium. perfringens, (Welchii) type A Nausea, abdominal pains, diarrhoea, gas formation Virus of infectious, Hepatitis (virus A) Infectious hepatitis Fluoride Excess fluoride causes fluorosis (mottling of teeth, skeletal and neurological disorders) Nitrates and Nitrites Methaemoglobinaemia especially in infants, cancer and tumours in the liver, kidney, trachea oesophagus and lungs. The liver is the initial site but afterwards tumours appear in other organs. Pesticide residues (beyond safe limit) Acute or chronic poisoning with damage to nerves and vital organs like liver, kidney, etc.

14 Factors favoring bacterial growth Food : Foods rich in Proteins, vitamins, and minerals, meat poultry, fish, eggs, diary products, cooked vegetables, cooked grains, also salads and green fruits and vegetables. Potentially hazardous food should be safely stored and prepared. Acidity (pH is a measurement of acidity or alkalinity) High acidic foods stop bacterial growth, but do not kill them. Bacteria’s prefers slightly acidic foods as meat, poultry & fish. Time

15 Temperature Bacteria’s grow when temperature is between 4  C to 60  C multiplying every minutes (Danger Zone). Below 4  C : Bacteria survive but grows slowly. Above 60  C : Bacteria stops growing. Oxygen (Air) Most bacteria need air or oxygen to grow. Clostridium botulinum can grow only in absence of oxygen. Moisture (Water) Most bacteria need air or oxygen to grow.

16 Bacteria - Control Keep potentially hazardous food out of ‘Danger Zone’ temperature i.e., 4  C to 60  C (2 hours Maximum). Keep food below 4  C or above 60  C. Cook food to safe temperatures (Reheat to 74  C min). Chill hot food quickly. (Rapid cooling technique). Wash hands before preparing and eating food. Clean and sanitize utensils, container and food preparation surfaces.

17 How food borne illness spread Animals Raw meat, poultry, fish (salmonella, Camppylobacter, E.coli), Insects, mice, pests, etc. People People carry microbes in their intestinal tract (E.coli, salmonella) and spread through the fecal-oral route. Staphylococcus Aureus (Staph) is present on skin, nose, throat and spread through coughing, sneezing, touching, infected cuts and sores on hands, etc.

18 How food borne illness spread Soil Fruits & Vegetables can contain (Salmonella, E.coli), on outer surface. E.g., tomatoes. Water Untreated water from lakes, streams, are rivers carry microbes E.coli, Salmonella, Staphylococcus Aureus (Staph), and parasites like Cryptosporidium and Giardia.

19 How food borne illness spread Chemicals Naturally poisonous food, e.g., some types of mushrooms (Amanita species). Food contaminated with synthetic chemicals Excessive use of food additives (MSG). Pesticides residues. Adulterants: Contamination & Intentional.

20 CONTAMINATED WATER ArsenicDizziness, chills, cramps, paralysis, death Barium Violent peristalsis, arterial hypertension, muscular twitching, convulsions, cardiac disturbances Cadmium ‘Itai-itai (ouch-ouch) disease, Increased salivation, acute gastritis, liver and kidney damage, prostrate cancer CobaltCardiac insufficiency and myocardial failure Lead Lead poisoning (foot-drop, insomnia, anaemia, constipation, mental retardation, brain damage) CopperVomiting, diarrhoea TinColic, vomiting ZincColic, vomiting MercuryBrain damage, paralysis, death

21 Allergens Milk & Dairy products Eggs, Wheat Soy Peanuts Tree nuts (almonds, cashew nuts, Brazilian nuts) Fish Shellfish Chemicals
