National Animal Health Forum (NAHF)

Release for all Media from the NAHF

Brucellosis is a disease destroying the Livestock industry which can also be transmitted to Humans 

Brucellosis is spreading unabated in a number of SA Provinces. The Department of Agriculture , Forestry and Fisheries together with industry’s National Animal Health Forum are combining efforts in an action to control and eventually eradicate Brucellosis from South Africa. This will necessarily mean that all parties ie. Farmers, Livestock production organisations, DAFF and South African Veterinary Association through RuVASA practitioners will all have to be committed to this cause if progress is to be made over the next few years to bring Brucellosis under control.
The NAHF in conjunction with DAFF will be issuing press releases over the next few months to increase awareness of this disease among all stakeholders. We urge all media to become involved in our combined efforts to keep all parties well informed. We look forward to a fruitful relationship with the media and ask that you submit any queries to Marzanne Polydorou (admin@csvet.co.za). 

Yours sincerely 

Dr Pieter Vervoort (BVSc)
Chairman NAHF

Note to Journalists :
South African Feedlot Association
The SA Feedlot Association is an umbrella organisation that addresses collective interests of the South African Feedlot industry which collectively markets close to 80% of the total beef production in South Africa.
Following the recent deregulation of the South African Meat Industry, a number of the larger feedlots have now vertically integrated into processing, wholesaling and even retailing their own quality beef products.  For more information go to www.safeedlot.co.za.
Ms Thoko Didiza, Minister of Agriculture, announced on 31 May in Parliament, that the OIE declared South Africa free of Foot-and-Mouth disease.
"How safe is our Beef" is a topic of media attention which increases or decreases according to issues and incidents in the world beef industries.
Very rarely are either the media or consumers at large, sufficiently knowledgeable to make any kind of intelligent judgement on potential foodborne hazards and their stance on the subject is traditionally emotional and void of any scientific substantiation while falling prey to eloquent food fear-mongers.
As stated by Dr. Dixie Le, Governor of Washington State 1989, "despite all the evidence of our physical wellbeing - beyond the dreams of all previous generations - we seem to have become a nation of easily-frightened people.  Perhaps we can be classified as the healthiest hypochondriacs in the world."
The use of anabolic steroids in animal production to enhance the well-being of animals while maximising feed efficiency is one such perceived hazard which warrants objective comment.
The growth of all tissue body parts is under the direct control of hormones,  They are found everywhere in the animal kingdom and are secreted and consumed by man and animal daily in varying amounts.
Vegetables contribute close to 90% of all compounds with hormonal activity ingested in man's diet.
Vegetables contain specific phyto hormones which are also found in fodder consumed by domestic animals.
Phyto hormones with an ostrogenic activity are also found in natural vegetable products consumed daily by man, for example, potatoes, cherries, apples, cabbage, beans and hops used in the preparation of beer as well as in soya and sunflower oils.
Interestingly enough, beer contains more than ten times the hormone level of beef which means that eleven steaks of 300 grams each will have the same amount of hormones as a 340ml can of beer.
It is also interesting to compare the levels of hormones in beef with some other commonly used "natural" foodstuffs, specifically comparing 500 grams of product.
Equivalent amounts :
Soyabean Oil: 1 000 000 ng /500g
Cabbage: 12 000
Wheat germ: 2 000
Peas: 2 000
Eggs: 7 500
Ice cream: 3 000
Milk: 65
Beef from non-implanted cattle: 8
Beef from implanted cattle 11
It is worthy of note to compare estrogen levels in healthy humans :
Pregnant woman:: 900 000 000 ng / 500g
Non-pregnant woman : 5 000 000
Adult man 100 000
Pre-puberal children 40 000
Hormones are used by livestock producers to increase lean meat production and to improve the efficiency of conversion of feed energy to lean meat.
When they are used, it is only done on the recommendation of a specialist veterinary physician and the withdrawal periods prescribed by the manufacturers are always allowed before the cattle are sent to the abattoir.
Five hormones have been approved for use in beef production by our Registrar under Act 36 of 1947, after many years of extensive local and international trials and human safety tests were presented.  These are estradiol, progresterone and testosterone, which are the natural hormones and two synthetic hormones, zeranol and trenbalone acetate.  Studies in the US indicate that any increase above the natural level of these naturally-occurring hormones in implanted cattle is so minute it is insignificant and residues from an implant cannot be differentiated from naturally-occurring hormone levels.
The US Food and Drug Administration - one of the strictest human health safety organisation throughout the world - has approved the use of properly administered hormonal implants for beef production.
Implant safety is also implied by the fact that in 40 years of application, no safety problem has ever arisen.
Advertising strategies around "Natural Beef" have been structured to convince consumers that "Normally Produced Beef" is unhealthy and inferior while the "natural" product is from an "uncontaminated, pure" background which raises concerns in the consumers' minds regarding the safety and healthiness of normal beef.  Studies conducted by the centre for Red Meat Safety found that it is highly unlikely that there is any difference in the presence of harmful chemical residues between "normal beef" and "natural beef".
The "Hormone Ban" is one of the better known non-tariff barriers implemented by a country to protect its domestic market.
The "Hormone Ban" implemented by EU member countries is often cited as being scientifically based proof of the "dangers" involved in consuming hormone treated products.
It is a well-established fact that the whole "Hormone Ban" issue was for two reasons :
  • To prevent EU producers contributing even more to their over-production of beef and adding larger volumes to the large Intervention Stockpile to keep US Beef exports out.
  • The banning of US Hormone Beef was taken to the International Court and the European community lost its case with the conclusion that there were no scientific grounds whatsoever to substantiate the EU claim that beef ex-America was a hormone health hazard.
It was concluded that the attempts to ban US hormone-implanted beef were not based on any scientific evidence whatsoever and the US has been granted commensurate trade relief.
1. Growth hormones occur naturally in all animals and humans.
2. Growth hormones occur in higher levels in other food products classed as natural and wholesome.
3. The following prominent agencies renowned for their concern for human food safety concluded that growth hormones used in beef production pose no safety risk to humans consuming the beef.
  • US Food and Drug Administration
  • World Health Organisation (WHO)
  • Food and Agriculture Organisation (FAO)
  • Codex Alimentarius
  • European Economic Community (EEC)
  • Scientific working Group on Anabolic Agents (1981)
  • European Community (EC) Scientific conference on Growth Promotion in Meat Production (1995)
One can only conclude that any fears relative to risk to human health because of implantation of hormones in beef production units are totally unfounded.
