The Hidden Dangers of Consuming Sick Pork: Don’t Take Your Health for Granted
Professor Nguyen Duy Thinh, an expert in Biotechnology and Food Technology, warns that meat from sick pigs can have serious short-term and long-term health consequences and should never be consumed. While cooking may kill most bacteria and parasites such as worms, some particularly dangerous strains of bacteria, such as Staphylococcus aureus, can survive high temperatures and cause infections if consumed.
For example, Staphylococcus aureus can form heat-resistant spores that remain in the meat even when thoroughly cooked. These spores can develop into bacteria that cause digestive issues and, in severe cases, lead to blood infections when they enter the body.
More worryingly, certain bacteria that affect pigs, such as cholera, can produce toxins that are heat-stable and not destroyed by cooking. These toxins can easily enter the bloodstream and cause dangerous complications, including sepsis, liver, and kidney damage.
Professor Thinh also emphasizes that improper handling, such as using knives and cutting boards contaminated with bacteria from sick pork, can lead to cross-contamination of other foods. This poses a significant risk to the elderly, young children, individuals with pre-existing conditions, or those with compromised immune systems, who are more susceptible to foodborne illnesses.
In addition to acute risks, consuming sick pork may also have long-term consequences. Many farms use antibiotics or medications to treat sick pigs before slaughter, and consuming meat with residual drugs can have severe health implications, increasing the risk of antibiotic resistance and cancer.
Pig Diseases That Can Affect Humans – Early Detection is Key
While diseases such as swine flu, cholera, cysticercosis, and Porcine Reproductive and Respiratory Syndrome (PRRS) may not directly affect humans, consuming meat from infected pigs can still expose individuals to dangerous bacteria and toxins.
Here are some key indicators of unsafe pork that consumers should be aware of:
Cysticercosis (Cystic Pork): The meat has oval-shaped white spots, about the size of a bean, which are cysticercus cysts.
Salmonellosis: The pig’s skin may show purple bruises or petechiae, its ears may appear purple, and the meat may be soft and lack elasticity.
Cholera: Small, red spots similar to mosquito bites appear under the skin, especially around the ears and belly.
Pasteurellosis: The meat shows distinct patches of blood and bruising.
Hepatitis: The meat has an abnormal yellow color.
Branding: The skin shows unevenly sized red or purple circular marks, resembling “branding.”
Additionally, diseased pork organs often emit a strong foul odor due to decomposition and are less likely to be sold. However, other parts of the meat, such as the shoulder, loin, and ham, can be easily mixed and widely consumed, which consumers should be cautious about.
Tips for Choosing Healthy and Safe Pork
How can you ensure that the pork you’re buying is truly fresh and hygienic? According to Professor Thinh, consumers should pay close attention to five critical factors: elasticity, color, surface, smell, and the condition of the skin (rind) of the meat.
1. Elasticity: Gently press the surface of the meat with your fingertip. Fresh meat will quickly return to its original state. If the indentation remains or disappears slowly, the meat may be old, frozen, or starting to spoil.
2. Color: Fresh pork usually has a light pink to bright red color, with a slightly sticky surface when touched. The fat is white or creamy white. Avoid meat with dark red, pale, or grayish colors, which could indicate sick or stale pork.
3. Meat Surface: Avoid meat with excessive moisture or a slippery, soft texture, which may indicate that the pig was injected with water before slaughter, or the seller is trying to increase its weight by soaking it in water. Fresh meat has a dry, slightly sticky, and elastic surface.
4. Smell: Healthy pork has a distinctive fresh meat aroma. Avoid meat with unusual smells, such as antibiotics, strong fishy odors, or unnatural fragrances, which may be used to mask spoilage.
5. Skin Condition: Healthy pig skin is bright pink, smooth, and taut, without any unusual marks or purple spots around the hair follicles. If the skin has been removed or shows signs of unusual trimming, be cautious, as this could be an attempt to hide signs of disease.
Note: Choosing safe pork requires vigilance and attention to detail. Don’t compromise your health or fall prey to cheap prices by ignoring warning signs. As a smart consumer, you play a crucial role in promoting food quality and safety in the market.

“The Ultimate Guide to Choosing Antibiotic-Free Pork”
Antibiotic-ridden pork is a growing concern due to the unregulated use of antibiotic growth promoters in animal feed. While it may be challenging to detect antibiotic residues with the naked eye, there are telltale signs to look out for. The key indicators of antibiotic residue are noticeable changes in the color and texture of the meat and fat. When cooked, the meat will not exude the usual amount of moisture, setting it apart from regular, uncontaminated pork.
