“MEAT” Superbugs

Antibiotics controversies

In North America, about 23,000 deaths are reported every year due to superbug infections (antibiotic resistant infections). Antibiotics are given as drugs to treat bacterial infections. When the bacteria become resistant to three or more types of antibiotics, they lead to the rise of superbugs (Consumer Reports, 2015). Many factors can contribute to the cause of these antibiotic resistant superbug infections, one of which is the abuse of antibiotics in animal farm practices. Consumer Reports did a 3-year investigation on raw meat products revealing superbugs present in four major types of raw meat: turkey, chicken, beef, and shrimp. Samples taken in for testing showed superbugs present in: 84% of turkey samples, 57% of chicken samples, and 14% for both beef and shrimp samples (Consumer Reports, 2015). There may be a big gap between certain meat types, but this study was done over three years, and the sample size ranged from 168 to 304. As it is shown above, the presence of superbugs in raw products indirectly proves the overuse of antibiotics in animal farm, which leads to the death of superbug infected patients.

On the other hand, according to the Consumer Reports, the meat and poultry industries claim that drugs (antibiotics) were not widely overused and the use of drugs are important to ensure animal’s health, welfare and food safety to a certain extent. However, the science behind it suggests otherwise.

How does antibiotic resistant occur?

DNA mutations often occur naturally in bacteria, but when a gene that is responsible for the bacterium’s survival is mutated, antibiotic resistance may appear. Antibiotic resistance happens when a pathogen manages to escape from being killed by antibiotics and therefore, is able replicate in numbers. However, it does not need a daily routine of antibiotic applications to encourage superbugs to flourish as there is also another mechanism in promoting the multiplication. Gene transfer is a common mechanism that happens as a DNA of an organism is passed onto another organism that is nearby; consequently, infecting neighboring organisms.

Will it cause extreme harm?

No, as long as you cook the meat to the appropriate temperature, harmful pathogens should not be able to survive and infect us. However, if we do get superbug infections from eating meat that were not cooked properly, it would become a life-threatening situation since superbugs are resistant to all known antibiotics. If there are people who are very concerned with superbugs in the meat, switching to meat products that are labeled “Organic” or “No Antibiotics” will minimize the chances of superbug exposures.

(Meat) European parliament votes to ban cloning of farm animals

What is your opinion on human cloning? Have you ever thought about having another identical self? Not only the surface but genetically identical? To certain extent, many would feel leery even thinking about it.

Then what are your opinions on animal cloning of animals? Unlike human cloning, there seems to be distinct split opinions between different countries. Some countries suggest a positive perspective toward the idea of cloning animals for meat productions. In 2008, FDA has ultimately concluded that meat from cloned animals and offspring of clones are safe to be consumed by consumers. They added that it is as safe as those foods from conventionally bred animals. Since then, products of cloned animals, which include cow, goat and pig, are allowed to be sold in the market without any labelling that differentiate cloned animals from conventionally bred ones.Screen Shot 2015-11-06 at 11.10.41 PM

How did this issue on cloned animals arise in the first place?

The history of cloning started with a female domestic sheep named Dolly in Scotland in 1996. Cloning of animals is a technique that involves use of adult somatic cell by replacing the nucleus of unfertilized ovum to nucleus of the somatic cell and produces an embryo. After its first introduction from Scotland, cloning of animals has been studied and practiced ever since.

Ironically, in 8th of September 2015, the European Parliament voted to ban animal cloning completely including all farm animals, their descendants, and products derived from them that include imported products into the Europe. With issues regarding animal welfare and ethical considerations, the European Parliament has decided to fully ban the practice of cloning animals. In addition, despite FDA’s claim that cloned animals are safe to consume by human, there are several concerns associated with consumption of cloned animals. Cloned animals tend to have problem delivering live young and produce lameness and in order to overcome this issue, they are treated with hormones and antibiotics. With consumption of these heavily dosed cloned animals, number of health risk may arise such as allergenicity, development of antimicrobial resistant microbes, toxicity, carcinogenicity and much more. To add to this notion, European Food Safety Authority has stated that there are still uncertainties in the risk from the lack of studies and evidence available for information on safety of cloned animals except cattles and pigs.

WiScreen Shot 2015-12-02 at 2.09.54 PMth two very different opinions toward consumption of animals from North America and Europe, it is hard to choose which studies are true. The controversy of having cloned animals for meat production and other consumption is still unresolved as no one possess enough evidence to fully back up their opinions.

How do you feel about animal cloning now? Did this persuade to change your mind to be against cloned animals or not?

Let me know on the comments below!

(Meat) Pet Food Safety is As Important As Human Food Safety

Cute Cat

Surprise! Human is not the only species on earth that consume meat. Cats and dogs we have at home consume meats as well. As raising pets in the family become more and more popular, pet food becomes a high demand in the market. Industrialization comes along and a lot of companies try to lower their price by using many different methods.

Chemical Structure of Melamine Cyanurate

 

One of the method was to lowering the protein content by substituting meat with wheat gluten. Wheat gluten itself does not cause any harm to animals, however, the additional of melamine and cyanuric acid does. Melamine contains 66% nitrogen and it is used for plastic production (Suchy et al., 2009). Cyanuric acid is a bleaching agent and it contains non-protein nitrogen like melamine (Suchy et al., 2009). The combination of melamine and cyanuric acid forms melamine cyanurate and it is an insoluble compound that can block renal function (Suchy et al., 2009). Eventually, it causes renal failure in animals and eventually death (Suchy et al., 2009).

 

At late 2006 and early 2007, gluten suppliers in China decided to add melamine and cyanuric acid into the wheat gluten to higher the nitrogen value (FDA, 2009). Most protein analyses were based on amount of nitrogen in sample so a higher nitrogen value could trick buyers by claiming a high protein value for their product (FDA, 2009). Buyers would not know that they were buying wheat gluten with non-protein nitrogen chemicals like melamine and cyanuric if the chemicals were not listed out. Pet food companies purchased the wheat gluten and added into their pet food products without knowing the danger of it (FDA, 2009).

“cut and gravy” style pet food

 

In many affected brands, Menu Foods Limited had the highest impact. Menu Foods Limited was a company based in Canada and it sold pet foods across Canada and United State (Smith, 2007). The company “cut and gravy” style pet food was first reported to cause renal failure and death (FDA, 2009). It was also the first company began to recall and had the largest recall in comparison with other companies (Smith, 2007).
Although there were 8500 animal deaths reported to FDA in related to this incident, there were no specific number of affected animals according to FDA (U.S. Food and Drug Administration) because of lack of surveillance network (FDA, 2009; Heavey, 2007).

 

After the incident, FDA developed a network called Pet Event Tracking Network (PETNet) to improve surveillance (Dangin et al., 2015). The database allows FDA and state agencies to share information about potential outbreaks and pet-food related incidents instantaneously (Dangin et al., 2015). The system was finally finalized at 2011 (Dangin et al., 2015). You might think surveillance would improve after this tragedy, however, nothing has really changed.

Jerky Dog Treat That Required to Be Recall at 2015

 

In September 2015, a jerky dog treat has reportedly contaminated with amantadine and required to be recall (FDA, 2015a) . Amantadine is an antiviral drug to treat Parkinson’s disease (FDA, 2015b). Certain farms and plants used it to treat avian flu (FDA, 2015b). Although it is allowed to use as a medication for animal in certain countries, it is not approve to be in pet food in the U.S. (FDA, 2015b). This is not the first time that happen in human history. In 2014, there were more than 4800 complaints in regarded of jerky pet treats (Desk, 2014; FDA, 2015b). More than 1000 dogs were reportedly dead because of jerky pet treats from China (Desk, 2014; FDA, 2015b). Although there is no definite correlation with amantadine and the 2014 incident, it is one of the potential cause (Desk, 2014). In term of the source of illness, it is still unknown according to a report given out by FDA in February 2015 (FDA, 2015b). Moreover, complaints in regard of jerky pet treat is still continuing in 2015 (FDA, 2015b).

 

Dogs and cats cannot choose what they eat. Human have a great responsibility on what they provide to their pets. In 2015, nothing has really improved in term of pet food safety. In the future, we should really make sure that no more poor animals are dead because of our greediness; therefore, we should continue to improve our regulations and surveillance program to protect them.
