When it comes to meat, most people have an opinion about which proteins are cleaner or dirtier. The old adage says that chicken is filthy while pork is unclean. But does science support these preconceived notions? Let’s dig into the details of contamination rates and cleanliness for chicken versus pork.
Why Chicken Has a Reputation for Being Dirty
For years, consumers and food experts have considered chicken one of the dirtiest meats you can buy. Several factors contribute to this perception:
-
Salmonella prevalence: Chicken is the meat most commonly associated with salmonella contamination. Up to 25% of raw chicken sold in stores may harbor salmonella bacteria.
-
Campylobacter risk After salmonella, campylobacter infections are the second most common foodborne illness linked to chicken consumption
-
Messy living conditions Chickens often live crowded together, walking through and pecking at feces. Their close quarters are breeding grounds for pathogens
-
Feces contact: During processing, chicken carcasses may come in contact with fecal matter, contaminating the meat.
-
Extensive handling Chicken requires more handling and intervention during slaughter than pigs, offering more chances for contamination
The high prevalence of foodborne pathogens and less-than-sanitary living conditions contribute to chicken’s dirty reputation. Proper cooking kills bacteria, but mishandling raw chicken can spread germs.
How Clean Is Pork in Comparison to Chicken?
Pork also faces safety concerns, but benefits from some advantages:
-
Lower salmonella rate: Only about 6-10% of pork may contain salmonella, a significantly lower prevalence than chicken.
-
Single stomach: Pigs have a simple single stomach, compared to the dual stomachs of chickens, reducing harbor points for bacteria.
-
Shorter supply chain: Pork typically travels from farm to table quicker than chicken, reducing handling and contamination risks.
-
Fewer interventions: Pork carcasses undergo fewer intervention steps during slaughter, lowering chances for cross-contamination.
-
Better living conditions: Pigs are typically housed indoors on concrete floors rather than dirt, and have less physical contact than chickens.
While pork faces its own cleanliness challenges, the meat overall may contain lower levels of common foodborne pathogens than conventionally raised chickens. However, organic, free-range and pasture-raised chickens can deliver much cleaner meat.
Best Practices for Keeping Chicken and Pork Safe
Proper handling in the kitchen is crucial for keeping all meats safe, whether chicken, pork or other proteins:
-
Cook to safe internal temperatures (165°F for chicken; 145°F for pork)
-
Prevent cross-contamination by separating meats from other foods
-
Use separate cutting boards, utensils and plates for raw meats
-
Never place cooked meat back on a surface/plate that held raw meat
-
Refrigerate promptly; freeze for longer storage
-
Thaw in the refrigerator rather than on the counter
-
Marinate meats in the refrigerator
-
Wash hands thoroughly before and after touching raw meat
-
Take care not to splash chicken/pork juices around the kitchen
While more contamination risks may exist inherently with chicken, smart handling and cooking of all meats reduces foodborne illness risks significantly.
Common Pathogens in Chicken and Pork
Let’s take a closer look at the typical pathogens that may be present in chicken and pork if contaminated:
Common Chicken Pathogens
-
Salmonella – The most widely distributed foodborne pathogen linked to chicken. Causes salmonellosis.
-
Campylobacter – Leading bacterial cause of foodborne diarrheal illness. Usually not life-threatening.
-
E. Coli – Potentially deadly Shiga toxin-producing E. coli is a severe hazard.
-
Listeria – Causes listeriosis, a serious infection in high risk groups. Rare in properly cooked chicken.
Common Pork Pathogens
-
Yersinia – Causes gastrointestinal issues. Improper cooling and reheating may increase risks.
-
Toxoplasma – Protozoan parasite causing toxoplasmosis. Problematic in immunocompromised people if undercooked.
-
Salmonella – Not as prevalent in pork as chicken but still a concern.
-
E. Coli – Shiga toxin-producing strains are uncommon but would be especially virulent.
Proper cooking destroys all of these pathogens, but cross-contamination of utensils and surfaces can still spread bacteria if raw meat is handled carelessly.
The Impact of Farming Methods on Cleanliness
For both chicken and pork, farming approaches can significantly impact cleanliness:
-
Cage-free/free-range – Allowing chickens room to move lowers feces contact risks. Pasture access further reduces contamination.
-
Organic – Organic production protocols emphasize sanitation, pathogen testing and antimicrobial interventions.
-
Antibiotic-free – Reducing antibiotic use promotes better immunity in animals to resist pathogens.
-
Small local farms – Shorter supply chains and care taken by smaller producers boosts safety.
While organic, local and sustainable practices don’t automatically equal safer meat, they do emphasize approaches that lower risks.
The Takeaway: Cook Thoroughly and Handle Carefully
While chicken may carry higher baseline levels of common foodborne pathogens, pork also requires caution during handling and cooking. Following best practices in the kitchen is more pivotal for safety than the inherent cleanliness of the raw meat itself. The bottom line? Cook meats thoroughly, employ cross-contamination prevention measures, and handle raw proteins carefully. If in doubt, remember the sage advice of Julia Child: “Be careful when you’re handling chicken, and whatever you do, don’t cross-contaminate!”
Frequently Asked Questions About Chicken and Pork Cleanliness
Here are answers to some common questions consumers have regarding chicken versus pork safety:
Is chicken more likely to make you sick than pork?
Yes, chicken is more likely to contain foodborne pathogens, especially salmonella and campylobacter bacteria. However, pork can also harbor dangerous germs if undercooked or mishandled.
Should you wash chicken before cooking it?
Washing raw chicken is not recommended, as it can spread pathogens via splashing. Cooking to a safe internal temperature is the only way to kill bacteria present.
Is organic chicken cleaner than conventional chicken?
Organic chicken may have lower contamination rates due to production protocols focused on sanitation and disease prevention. But proper handling is still essential.
Is pork safe if it’s slightly pink after cooking?
No, pork should always be cooked to 145°F internally and allowed to rest for 3 minutes. Any residual pink indicates undercooking and the potential for surviving bacteria.
Which has more antibiotic resistance – chicken or pork?
Overuse of antibiotics in conventional chicken production has promoted more antibiotic-resistant strains of salmonella and campylobacter in chicken than in pork.
Does brining chicken or pork help sanitize the meat?
Brining using salt, sugar and spices may reduce microbial populations slightly but does not constitute a full sanitation wash. Thorough cooking is still required.
Can you get food poisoning from touching raw pork or chicken?
Yes, handling raw pork or chicken can result in food poisoning if germs are transferred to your mouth directly or via cross-contamination of kitchen surfaces.
