• …Say some preserve meat with chemicals used for corpses

 

Experts have observed that preserved meat is common in the market.

Dr Isaiah Okere, a meat scientist at the Institute of Agricultural Research and Training (IAR&T), Ibadan, has warned against the use of chemicals for the preservation of meat and other food items.

Dr Okere gave the advice in an interview with the News Agency of Nigeria (NAN).

He said chemicals such as formaldehyde or its derivative, formalin, used to preserve corpses were sometimes used to preserve meat and fish.

According to him, such chemicals are known to be carcinogenic (can lead to cancer) affecting vital organs like kidney, liver and lungs. 

How to identify fresh meat

Dr Okere said meat or fish preserved with formaldehyde/formalin could be easily identified as it was always stiff and odourless.

He said, “To know fresh meat, one should examine the colour; red meat should be bright red, but if it turns a bit purple, it’s still ok, but it means it has been exposed to some oxygen.

“Ensure to press the meat firmly with your finger, if it springs back nicely, it is fresh, if not, it is most likely old because it is losing its firmness.

“Meat should never smell like bleach, ammonia or anything foul.”

On meat preservation, Dr Okere recommends refrigeration, stressing that typically refrigerated storage life for fresh meat is five to seven days.

He, however, said with erratic electricity supply it was advisable to limit refrigerated storage to between two to three days.

Dr Okere said, “Freezing is a better option in the face of erratic supply of electricity, and storage life can last longer (running into months) than refrigerated storage.

“Meat can be vacuum-packaged (packaging free of oxygen), which extends the storage life under refrigerated condition to approximately 100 days.

“Since vacuum packaging is free of oxygen, it minimises the oxidation of the unsaturated fatty acids and slows the development of rancid meat.

“Also, drying is another method of meat preservation, as it removes moisture from meat products so that microorganisms cannot grow.

“Dry sausages and frozen-dried meat are examples of dried meat capable of being stored at room temperature without rapid spoilage.”

He also said smoking meat, as well as currying with a mixture containing salt and other natural preservatives, decreased the available moisture in the surface of meat products, preventing microbial growth and spoilage.

The meat scientist underscored the need to protect oneself by observing these precautions, adding that a good risk reduction measure was to wash all food (meat) thoroughly under running water to get rid of contaminants.

Dr Okere said, “Meat should be cooked thoroughly before consumption because temperatures of 75°C or above aid removal of formaldehyde.

“It is advisable to purchase meat and fish products when they are fresh and have the meaty or fishy smell characteristics.”

Also, Dr Mutiu Oladele-Bukola, a veterinary doctor at IAR&T, said a slice of good meat would have a clear marble-like pattern and should feel slightly hard when cold.

Dr Oladele-Bukola said, “The colour of fresh meat should be bright red, the redder the meat, the fresher it is.

“If the meat is turning reddish-brown, that means it has been exposed to air for at least half an hour.”

According to him, consumers determine quality meat as one with desirable colour, firm texture, less drip, high marbling and moderate visible fat with fresh meat smell.

He said, “Discoloration, soft texture, large amount of drip, less marbling, excessive visible fat and abnormal meat odour are considered poor quality traits for fresh meat.

“It’s, therefore, highly recommended that consumers should watch out, buy and eat fresh meat for a healthy life.” (NAN)
