Bacteria are ubiquitous in nearly all environments we inhabit and are essential to the ecosystem. They serve various functions, impacting human health in both positive and negative ways. For instance, beneficial bacteria like those in the Lactobacillus group are renowned for promoting intestinal health and bolstering the immune system.
Conversely, harmful bacteria can lead to severe infections; examples include Salmonella and Campylobacter, two of the most prevalent foodborne pathogens that affect millions globally, often resulting in outbreaks that cause debilitating—and in some cases, fatal—illnesses. Foods often implicated in these outbreaks include raw or undercooked eggs, unpasteurized milk, and different types of meat, particularly poultry. Contamination can occur at any stage, from production to food preparation, underscoring the importance of safe food handling practices.
After consuming contaminated food, symptoms of infection generally appear within 12 to 36 hours, manifesting as fever, headache, nausea, vomiting, severe abdominal pain, and diarrhea that can persist for 2 to 7 days. This situation not only affects individuals’ health and well-being but also presents a continuous challenge to public health systems. Thus, increasing awareness of food safety practices is crucial for preventing contamination and safeguarding community health.
Man is the only animal that can remain on friendly terms with the victims he intends to eat until he eats them.

What World Agencies Are Saying

The World Health Organization (WHO) estimates that each year around 600 million, or 1 in 10 people worldwide, become ill due to food poisoning, resulting in a tragic loss of 420,000 lives. The situation in the United States is similar, with approximately 1.35 million individuals infected annually by Salmonella, one of the most common bacteria associated with food poisoning. Among the most vulnerable groups, the elderly and children under 5 years of age stand out as the primary victims of this concerning reality, accounting for about 125,000 deaths each year.
A report prepared by the World Bank in 2019 highlighted the alarming economic burden of foodborne diseases, with annual losses estimated at US$95.2 billion. Additionally, the costs associated with treating these illnesses are roughly US$15 billion, worsening an already serious public health issue. Foodborne illnesses are largely the result of cross-contamination, which occurs when pathogenic microorganisms are transferred from contaminated food, utensils, or surfaces to other foods, utensils, or surfaces that were previously uncontaminated.
One common practice in meat preparation, especially with chicken, is washing it before cooking. However, this apparent concern for hygiene can be extremely harmful. Washing chicken, for instance, can create unwanted splashes that spread thousands of bacteria, such as Salmonella and Campylobacter, which can easily transfer to clothing, hands, arms, utensils, surfaces, and nearby food. A study by the United States Department of Agriculture (USDA) revealed that these contaminated droplets can travel up to 50 to 70 centimeters from the sink where the meat was washed, creating an environment prone to additional contamination.
According to the Australian Food Safety Information Council, 60% of home cooks in Australia admit to washing poultry before cooking. Similarly, the UK Food Standards Agency found that over two-fifths of cooks in England routinely wash chicken during preparation. Justifications for this practice often range from the influence of family members who also do it to the desire to remove visible blood, impurities, or germs from food. However, all the agencies mentioned unanimously agree that washing poultry or other meats before cooking poses a significant risk to human health.
The belief that this practice is safe or prevents disease is, in fact, a misconception; it can lead to the further spread of bacteria rather than eliminating them. It’s important to understand that when handling raw chicken, for example, you are almost certainly dealing with bacteria like Salmonella and Campylobacter, if not both. Recognizing that washing raw poultry or other meats before cooking is a genuine problem is a crucial step in promoting food safety and preventing foodborne illness. Addressing inappropriate cooking practices is essential for protecting public health and reducing the alarming incidence of food poisoning cases worldwide.
What the Experts Are Saying
Experts in food safety and culinary practices have consistently advised against the common misconception that rinsing chicken with hot water, soap, vinegar, or lemon juice is an effective method for eliminating harmful bacteria that can potentially lead to foodborne illnesses. Despite the intention behind these practices, the reality is that using hot water, even at elevated temperatures, is generally insufficient to kill most bacteria typically found on raw meat. The levels of heat reached during a simple rinse, regardless of how hot the water is, do not meet the required thresholds needed to effectively neutralize harmful microorganisms.
Furthermore, the practice of soaking chicken in acidic substances such as vinegar or lemon juice has also been shown to be ineffective in killing bacteria. While these substances are indeed safe for consumption and can add flavoring to dishes, they do not possess the right levels of acidity necessary to eradicate all harmful bacteria present in the meat. It is important to understand that relying on these methods before cooking may do more harm than good, as they can not only compromise food safety but can also negatively affect the quality of the finished dish.
Using vinegar or lemon juice can lead to undesirable changes in the chicken’s texture, potentially making it tougher than desired, and may also alter the flavor profiles of the final meal. This can result in a culinary experience that is far from satisfying, diminishing the overall enjoyment of the dish.
Given the potential pitfalls associated with these rinsing and soaking methods, experts strongly recommend that individuals focus instead on proper cooking techniques. Thoroughly cooking chicken to the appropriate internal temperatures is the most reliable way to ensure that all pathogenic microorganisms are effectively eliminated. This not only enhances the safety of the meal but also preserves and, in many cases, improves the flavor and texture of the chicken. By adhering to recommended cooking practices, home cooks can help to guarantee that their meals are not only safe to eat but also delicious, creating a positive dining experience for themselves and their guests.
Bottom Line
One of the most effective ways to eliminate bacteria and ensure food safety is by maintaining a clean and hygienic kitchen. This includes not only regularly wiping down surfaces like countertops and tables, but also disinfecting utensils, cutting boards, and any equipment that comes into contact with food. Additionally, it is vital to prepare and cook food in sanitized environments to prevent cross-contamination.
Another key factor in bacteria elimination is the cooking process itself. When preparing meats, particularly chicken and pork, it is crucial to ensure that the internal temperature exceeds 70ºC. This temperature threshold effectively eliminates most pathogenic bacteria known to cause foodborne illnesses. To verify that this temperature has been reached, using a culinary thermometer is highly advisable. This tool provides an accurate way to monitor food temperatures, ensuring that your meals are fully cooked and safe to consume.
By integrating these practices into your food preparation routine, you promote a safer kitchen environment and enhance the health and well-being of everyone who enjoys your meals. The combination of a tidy kitchen and vigilant temperature monitoring forms a powerful defense against bacteria and food contamination.
