Signs And Symbols On Food Packs And Their Meaning

Many people just want to eat and do not care to know about what they are eating. This is one of the reasons people gain weight and later wonder why they are accumulating fat. We need to know the composition of the foods we eat so that we choose what is good for us and what is not. Some people have eaten foods that landed them in hospitals because they have refused to check the precautionary statements written of food packs.

Food laws have made correct and complete labeling a very important part of food manufacturing. Manufacturers are required by law to add labels to food packages to be a source of information that consumers like and trust. Since 2006, the major food allergens are required to be specifically noted on the Information Panel of the food label (i.e., fish, milk, soybeans, wheat, eggs, shellfish, tree nuts, and peanuts).

There are symbols that are printed on food packs to pass information to the consumer but often we either don’t check them or simply disregard them. This article will show you ten symbols or signs that you may have come across on food packages in the past. If you have not seen any of them before, you would likely come across it in the future. If and when you do, you would know the meaning.

11 Signs And Symbols On Food And Their Meaning

1. Microwavable or Microwave Safe Symbol

Manufacturers may use any of the above terminologies as they both mean the same thing. In one of my previous articles where I answered the question of “if microwaved foods are safe to eat or not“, I mentioned that there are plastics that are safe for use in the microwave. These plastics do not have toxic components that migrate into the food during microwaving.

microwavable symbol

So, how do you know if a plastic container is microwavable? The easiest way to confirm that a plastic container is safe for the microwave is to look for the Microwave Safe symbol on it. This stamp of approval, which includes three wavy lines to symbolize radiation (image above), basically says that the container can withstand the heat of the microwave without melting or releasing harmful amounts of chemicals.

2. Nutritional Compass or Nutritional Facts

Apart from the list of ingredients that make up a food product, most packaged food must have a listing of nutrients and related information on the Information Panel that is usually on the side or rear of the package. These would normally include such information as serving size, calories, fat, carbohydrates, sodium, protein compositions.

nutritional compass or facts

Claims such as “low fat,” “high fiber,” “reduced calories,” and “cholesterol-free” are also included on food packages as information to consumers who may have concerns about these components.

3. Suitable for Vegetarians Symbol

The Vegetarian Society defines a vegetarian as ‘someone living on a diet of grains, pulses, nuts, seeds, vegetables and fruits with or without the use of dairy products and eggs (preferably free-range).’ Having defined this, you should know that vegetarians try to stick with their veggies without adding animal foods to eat.

Since they are not part of the manufacturing of some of the foods they eat, they want to be sure that what they want to buy or eat is suitable for vegetarians’ consumption.

vegetarian label

However, the ‘Suitable for Vegetarians’ logo is not regulated. It is a ‘voluntary claim’, which means it is illegal for the labeling information to include anything that is false or likely to mislead. The symbol is shown above.

4. Treated with Irradiation (Radura logo)

For foods that have been treated with ionizing radiations, the Radura symbol comes along with the statement “Treated with radiation” or “Treated by irradiation” on the food label. With this, identifying irradiated food has been made very easy by binding food laws. These laws are also very strict.

There are many concerns over the consumption of irradiated foods and one of such is this that I shared on one of my recent posts assessing the safety of irradiated foods;

It states, “When food is exposed to high doses of ionising radiation, the chemical composition and nutritional content of food can change. Radiolytic by-products are often formed in irradiated food. Very few of these chemicals have been adequately studied for toxicity. One such chemical – 2-DCB – can cause DNA damage in rat colon cells at high doses.”

Whether irradiated foods are safe or not is not the subject of this article, you can read further on that by clicking here. Whatever decision you make for yourself on irradiated foods – whether to eat it or not, identifying irradiated foods is easy with the above logo.

5. Allergen declaration

Allergen declarations are mostly precautionary statements on food informing consumers that the food may have a component that one could be allergic to. I wrote on allergies not long ago and also mentioned some of the common allergens in food.

Gluten in wheat flour could be an allergen, people could be intolerant to lactose and find it difficult to digest milk. Other common food allergens include Crustaceans, Eggs, Fish, Peanut, Soybeans, Tree Nuts, and Sesame seeds. You can read more about that here.

gluten free logo

There are instances where symbols are used to declare the absence of an allergen. For example, gluten-free symbol (above) is relatively common.

6. Organic labelling

These are used on organic foods and its use is totally voluntary. The food must be organic up to a particular percentage before an organic claim or statement could be made on the label. For example, In Canada the use of the organic logo is only permitted on products that have an organic content that is greater than or equal to 95% and have been certified according to the requirements of the Canada Organic Regime.

Above, is the organic food label! There are food that the manufacturer will want you to keep frozen. There is a logo that indicates that. See on next page.

7. Keep Frozen symbol

This symbol tells you to keep food frozen in order to keep the quality and shelf life for longer period. Some food materials will deteriorate rapidly if stored at normal room temperature. This symbol usually looks like the one below.

keep food frozen

Food such as butter and margarine can be frozen for 3 months. Grated cheese can be frozen for up to 4 months and can be used straight from the freezer. These are examples of common foods that we may see the symbol on.

8. Waste Disposal Symbol

This symbol is used on many products other than food packages also. It is usually called the Tidyman. It tells you to dispose of this packaging carefully and thoughtfully. Do not litter. Throw them in thrash cans after you and not litter the ground with it.

waste disposal logo

Above is the symbol telling you to properly dispose of your food packaging.

9. The Mobius Loop (Recycle)

The Mobius loop can be used for two different terminologies that should not be confused with each other because they both refer to recycling. I will explain the two briefly and put the symbol too.

recycle symbol - mobius loop

The Mobius loop indicates that an object is capable of being recycled – not that the object has been recycled or will be accepted in all recycling collection systems. Sometimes this symbol is used to indicate that the packaging is a product of recycling. It could come with a percentage figure in the middle to explain that the packaging contains x% of recycled material.

10. Halal logo

According to the Codex Alimentarius (Food Laws) of the Food and Agriculture Organization (FAO), Halal food means food permitted under the Islamic Law. The animal to be slaughtered should be lawful according to Islamic law. The food should be prepared, processed, packaged, transported and stored in such a manner that it complies with the Codex General Principles on Food Hygiene and other relevant Codex Standards.

Muslims don’t eat pork, Halal logo may also indicate that the food does not contain pork or a product of it such as fat. It generally tells Muslims that the food does not contain anything they are prohibited from eating.

halal logo

When a claim is made that a food is halal, the word halal or equivalent terms or symbol (as above) should appear on the label.

11. Bar Code on Food Pack

Just about every package of food you have ever purchased or seen has a bar code printed on it but we just don’t bother to check them or see the information they contain. The bar code has more information beyond what many people think.

barcode on foods

When the barcode is scanned, the computer system automatically determines if the product need re-ordering. This is a piece of information that could be very useful to supermarket owners. The price of the product appears when the barcode is scanned. It can also be used to determine if the product is genuine.

These are some of the important and relatively common symbols on our food packages that we should pay more attention to.

Is It Safe To Consume Irradiated Foods? Answers!

“When food is exposed to high doses of ionising radiation, the chemical composition and nutritional content of food can change. Radiolytic by-products are often formed in irradiated food. Very few of these chemicals have been adequately studied for toxicity. One such chemical – 2-DCB – can cause DNA damage in rat colon cells at high doses.” This is just one of the numerous claims I came across in an article titled “Food Irradiation – the problems and concerns” on www.foodcomm.org.uk.

I am a graduate of Food Science & Technology and I studied Food Irradiation a little extensively at Masters level. I read a lot of reports and I know that consumer perception of foods treated with irradiation is more negative than those processed by other means. As a Food Scientist, I know that every food processing method changes the composition of our food material, loss of nutrients, binding of different components and/or formation of toxic substances in food.

The Important Benefits of Irradiating Food Materials

Before I address the issue of whether irradiated foods are safe or not, let me tell you why we irradiate foods and what advantages it comes with.

  1. We irradiate our foods to prevent food-borne illness. During irradiation, the genetic materials of illness-causing microorganisms in our foods are destroyed.
  2. Irradiation is being used to destroy or inactivate organisms that cause spoilage and decomposition of food. This extends the shelf life of foods.
  3. Irradiation can effectively replace the use of pesticides to get rid of insect pests in tropical fruits. Irradiation destroys insects and their eggs in fruits, thereby preserving the food material.
  4. Irradiation can also be used to prevent sprouting in food such as yam, potatoes, onions and delay ripening of fruit to increase longevity.

Irradiated food is a cold process unlike pasteurization and other thermal processes: hence the food is still essentially “raw or fresh”, because it hasn’t undergone any thermal process.

To cap it all, food can be subjected to irradiation to make them sterile for people with very poor immune system to consume. People who have poor immune system would have complications when they consumed food with even mild contamination. Irradiation can create the appropriate and essential foods for them.

Are irradiated foods safe or should you avoid them?

Let us get the the issue of whether it is safe or not. As far as people like me are concerned, food irradiation is a processing and preservation technique with similar results to freezing or pasteurisation. I have read many arguments for and against food irradiation – research has shown that when food are exposed to the right amount of dose, they are safe to consume. This is just like taking prescription drugs; there is dosage and when you take more than the right amount of dose, problem starts.

Also, the exposure time matters a lot. This is the length of time for which a food material was exposed to radiation treatment.

The opponents of irradiated foods have not been able to prove that irradiated foods will cause adverse health effects. What they all say is that “science has not been able to prove that irradiated foods do not cause adverse health effects after long term consumption”.

Studies have shown that foods are not significantly changed in nutritional value and they don’t become dangerous as a result of irradiation. For example, at irradiation levels approved for use on specific foods, levels of the thiamine are slightly reduced, but not enough to result in vitamin deficiency. This occurs in other forms of processing where heats destroys nutrients,  vitamins are leached when we cook in water and so on like that.

Let me use this opportunity to make it clear that irradiation does not make food radioactive. In food processing, the radioactive sources permitted do not generate gamma, electrons or x-rays of sufficient high energy to make food radioactive. Radioactive energy does not remain in food after treatment.

To conclude my argument for irradiated foods, the FDA website states on irradiated foods: “The FDA has evaluated the safety of irradiated food for more than thirty years and has found the process to be safe. The World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA) have also endorsed the safety of irradiated food.”

How To Know A Food That Has Been Irradiated

What are irradiated foods? Are irradiated foods safe? Is it safe to consume microwaved food? What foods are irradiated? How do I know if the food I purchased has been irradiated? These are all the questions that I will definitely answer, but not all in this post. This post is just to show you how to identify irradiated food, so, it is going to be very short and straight to the points. There are just two ways to know irradiated foods and I will share them below.

How Will I Know if My Food Has Been Irradiated?

Many people in different parts of the world have shown serious concerns when it comes to the issue of irradiated foods and genetically modified foods. Many of them agreed that irradiated foods are not safe and hence, should not be consumed. We all have the right to determine what to eat. Food manufacturers are also bound by law to reveal some special treatments foods are subjected to, so it is easy to know an irradiated food. You can then decide whether you want to eat it or not.

Here are the two things to look out for;

1. International food laws and food laws in countries where irradiated foods are packaged, shipped to, and consume require that foods that have been exposed to ionizing radiations be labelled with the Radura symbol. So, you can look for the Radura symbol (shown below) on food packages.

2. The food must also, in addition to the Radura symbol, come along with the statement “Treated with radiation” or “Treated by irradiation” on the food label. With this, identifying irradiated food has been made very easy by binding food laws. These laws are also very strict.

For example, bulk foods, such as fruits and vegetables, are required to be individually labelled or to have a label next to the sale container.

In my upcoming posts, I am going to address the questions I asked us at the beginning of the article. What are irradiated foods and are they safe for consumption? Many of us consume microwaved food everyday and we would like to know if this is safe. I will definitely answer that too.
