Migratory animals carry more parasites.

Migratory animals carry more parasites.Every year, billions of animals migrate across the globe, carrying parasites with them and encountering parasites through their travels. Now, a team of researchers has discovered that animals known to migrate long distances are infected by a greater number of parasite species than animals that do not migrate. Migratory animals carry more parasites.

BLOODY STOOL IN DOGS.

The Presence of bright red blood in feces of dogs is common with dogs with bleeding in the lumen of intestine.The common cause in older dogs is usually cancer ,while younger dogs parasites are the usual cause.The color of the blood will give an indication of where the problem is,if the feces is dark and tarry then its digested blood indicating the problem is in the small intestine and stomach, while if the blood is frank and bright red the problem lies in the colon/rectum. The diagnosis involves more than the color of the feces,the history and other signs in the dog will help draw a logical conclusion.The common causes of bloody stool include infectious agents such as bacteria, protozoa,viruses and intestinal parasites. Dietary intolerance, allergy, colitis,bowel disorders , constipation and clotting disorders are also likely causes of blood in stool. Treatment will depend on underlying cause such as 1) antibiotics. 2)deworming medication. 3)adsorbent to coat lumen. 4)changes in diet. 5) provision of plenty water.

FOOD SAFETY.

Food safety refers to methods,procedures and protocols that are practiced in food industry.These procedures/protocol are put in place during processing, packaging and transportation. Food safety is very important to human health because it prevents food-borne diseases that could be fatal.Food safety prevents hazards in food that cause injury,illness and sometimes death.These hazards could be physical,biological or chemical in nature , found in food and drinks, have varying impacts on human health.The susceptibility of individuals to these hazards vary with children being major subjects followed by elderly older than 65, then pregnant women and lastly immune compromised individuals. The physical hazard include stones,broken glass,plastic cuts,jewelry,rings,pieces of fabric(shredding table cloth ) and boards e.t.c.The hazard usually occur during processing,packing and storage.The food processors are usually the major cause of these form of hazard; the work unit,tools and personal hygiene have all being pinned as sources of food hazard. Chemical hazard include poisonous substances,chemicals ,soaps,detergents or cleaning liquids that are spilled during food processing.Pesticides,rodenticides and paints have also being fingered as hazard in food industry. Biological hazards are microorganism ,which include bacteria,viruses and parasites.The parasites are usually tiny worms in beef,pork and fish; these parasites are usually found in contaminated water,used in processing.Bacteria grow in food under certain conditions such as low temperatures,fecal contamination,or cross contamination which result in food spoilage and food borne illness.These bacteria contaminate food during processing handling and storage. Viruses in food usually contaminate food during processing ,these are usually from food processors that are coughing,sneezing,and picking nose.These can be prevented by maintaining high level of hygiene by food processors. Food borne illness can be prevented by implementing the following ;1) high standard of personal hygiene. 2)temperature control. 3) preventing of cross contamination between various food items. 4)cleaning of utensils,working area and cutting boards. 5) proper packaging and storage. Personal hygiene will include washing hands before handling meat,after using toilet and after handling various raw food.The food processor must not wear jewelry and accessories that can easily drop off during production, nails must be cut short and clean,hair must be covered and neat clean clothing must be worn. The processor must wear clean overall,gloves and clean working shoes.The health status of food processors play a vital role in the level of safety of the food ,hence processors that are ill, coughing,sneezing, vomiting or have diarrhea should not handle food.Food operators must undergo regular checkup to ascertain health status,any case tuberculosis,hepatitis,HIV/AIDS should be reported. Hand washing plays an important role in food safety and the benefits cannot be overemphasized; hand washing removes microorganisms and should be done throughout the day.
