Food Contamination Still Exists

Food Contamination

Trial and error over time has seen foods that have an obvious toxic effects be excluded from the human diet. Today acute poisoning from any food uncontaminated by bacteria is rare, the contamination is from bacteria in foods that when handled, stored and cooked properly are not toxic.

This means that the far more important risk to our health is contamination of food by toxic biological substances such as bacteria and fungi. Bacterial contamination of food has been a major problem throughout human history. Acute illness from food contamination is characterized by symptoms, which may include: diarrhea, cramps, fever and vomiting.

The risk of death from food contamination is much higher for the elderly, people who have a weak immunity system and the very young. Long term affects may also be present due the infections caused by the contaminated food that can weaken the immunity system, thereby make the body more prone to contracting other disease and illnesses.

Although the refrigeration of food has greatly improved the situation, outbreaks of bacterial poisoning are still occurring today. This is happening principally as a result of inadequate cooking of food, improper cleaning of equipment, cross contamination of cooked and raw food and preparation of food too far in advance.

Illness is caused by bacteria multiplying in the intestines and by toxic proteins that the bacteria liberate there. The popularity of defrosting and cooking meat in microwave ovens often results in incomplete cooking and incomplete destruction of bacteria. Microwave ovens can have an uneven heat distribution, which results in both over cooking and under cooking.

A common food contaminant is e.coli, which is especially found in hamburger. It causes server diarrhea, which can be fatal. Bacterial contamination on the outside of the meat, which will be cooked, is normally harmless, since the heat will destroy the bacteria.

However when the meat is transformed from its original structure, some of the bacteria are transferred to inside the hamburger patty and if the cooking is inadequate the bacteria can survive and cause food poisoning.

In recent years there has been a rapid increase in food poisoning in most countries. The demise of home cooking and the popularity of fast food outlets and restaurants have contributed to this increase in food poisoning. In the US there are about 30 million cases a year, leading to about 10,000 deaths and an annual cost of $6 Billion dollars to the economy.

Since publication of the previous edition of this successful book, there have been many advances in the field of food science and metal analysis and these have been taken into account of in compiling this new edition. Data on metal levels in foods and diets have been updated with information gathered from recent international literature. More than 80% of the text has been completely rewritten and, as the addition of a new subtitle suggests, greater account is taken than in earlier editions of the importance of the nutritional properties of many of the metals that we consume.

In the compilation of this cutting-edge new edition, full account has been taken of the significant advances in the ready availability of multi-element analysis, improved sample preparation procedures and a growing interest in the content of chemical species in foods. Details of several metals, not considered in depth in previous editions but now widely used in the electronic and chemical industries, have also been included.

The third edition of Metal Contamination of Food is an essential reference book for food industry personnel, including those working in food processing, formation and ingredients, packaging, quality control and food safety. Nutritionists, public analysts and chemists will also find much of great use within the covers of this book. Libraries and laboratories worldwide in all universities and research establishments where food science and technology, nutrition and chemistry are studied and taught should

The Safe Food Handbook is an essential guide for everyone, especially those most vulnerable to unsafe food—pregnant women, older adults, young children, those with serious health conditions—and anyone who cooks for them. Dr. Heli Perrett provides clear guidance on how to:

Recognize the riskiest foods and places to eat
Protect yourself from dangerous microbes like E.coli and Salmonella
Reduce toxins that build up in your body
Learn which corners you can cut—and which you shouldn’t
Enjoy your favorite foods without hurting your health or your budget

Helpfully organized by food group, The Safe Food Handbook demystifies the perils in our food—infectious bacteria, deadly molds, hormones, antibiotics, toxins, irradiation, and even wax on produce. Risks lurk in . . .

Fruits and Vegetables • Fish and Shellfish • Meat and Poultry • Dairy • Eggs • Grains, Legumes and Nuts • and even Herbs and Spices

. . . but Dr. Perrett answers your questions on shopping (“What exactly does this label mean?”), eating out (“What should I avoid in restaurants?”), and food preparation and storage (“How long can I save these leftovers?”)—so you don’t have to worry. You’ll have the inside story on what’s really in your shopping bag—and on your fork.
