Chemical hazards: the raw materials may also be contaminated with chemicals and other pesticide residues weight loss green smoothie recipes buy xenical overnight delivery. Even if the hazard is eliminated at a later stage of the process weight loss pills videos xenical 60 mg line, any risk associated with raw materials should not be ignored weight loss zumba purchase xenical 60 mg mastercard. At each step of the process weight loss journal cheap xenical 60 mg with visa, consideration has to be given to the possibility of contamination with biological, physical, or chemical hazards. Biological hazards: Microbial destruction is a critical factor in food processing, and if adequate con trols are not in place, microbial contamination is a distinct possibility. However, microbial growth will take place only if the material is a suitable substrate and stored at a condition appropriate for growth. Physical hazards: Processes such as sieving, washing, inspection, and metal detection are designed to remove or reduce foreign matter present in a food product. For example, plas tic pieces can become embedded in the food product during a packaging operation, and metal pieces or shavings can get into the product via faulty machinery. Hazard Analysis and Critical Control Point 985 Chemical hazards: Any equipment that comes into direct contact with food items can contaminate the food if it has not been thoroughly cleaned. However, carton closure equipment that does not come into contact with food directly cannot be considered a possible hazard source. Control measures: If the hazard is not eliminated downstream, adequate control measures should be exer cised at the step under consideration. If vegetables are washed for the purpose of removing foreign matter and intended to be consumed uncooked, the washing step is critical and needs a high degree of control because of possible microbial contamination. However, if the vegetables are intended to be cooked, the wash ing step is for the purpose of removing soil and dirt and therefore needs a low degree of control. Displaying raw chilled seafood, poultry, and meat needs a high degree of control because it is important to keep the dis play temperature below 4? Process steps such as filling trays and handling of food require a moderate degree of control. Consideration has to be given to storage conditions, packaging requirements, and delivery instructions necessary to prevent the product from undergoing deterioration or spoilage. Biological Hazards: Products such as bottled wine, canned foods, and jam do not require special storage conditions, and hence there are no hazards associated with storage. For perishable foods such as meat, fish, and ice cream, the storage conditions are critical to prevent the growth of microorganisms. Vegetables require special storage conditions, but if abused, the hazards that can occur are less critical. Chilled and frozen foods may be subjected to unfavorable storage conditions (temperature/time) over long periods during transport. These food products require special packaging and the hazards associated with such products are critical. Physical Hazards: Food transported over long distances is subjected to a wide variety of storage con ditions and handling techniques. The hazards that can occur during the transport of food substances are assessed as to the extent of damage or deterioration. Few or no hazards are associated with food prod ucts that do not require special storage conditions or handling techniques. Some food products packed in glass or plastic containers require special storage conditions during transport to prevent damage and sub sequent spoilage. Chemical hazards: During storage and delivery, chemical hazards in a food product are often caused by unclean containers. Food ingredients are also transported to food producers, and in some instances contaminated substances may be transported in the same vehicle . Control measures: Controls are not necessary for food products such as canned foods, sugar, and salt. When chilled and frozen food products are transported, stringent control measures should be exercised. Some products that are transported over short distances in insulated packaging may not require special stor age conditions, and failure to maintain control over temperature/time may not have serious consequences. Mishandling of products, which leads to dete rioration of quality, has been cited as one of the causes of consumer dissatisfaction. Hazards can some times occur in the hands of the consumer as a result of inappropriate usage and abuse by the consumer. Inappropriate usage: Food products that can be safely consumed by the general population cause no risk. Some food products that can be safely consumed by a section of the population may not be toler ated by others, although the effects of such a hazard may not be significant. Abuse by the consumer: Food products that do not require special storage conditions or handling cause no hazards in the hands of the consumer. However, some food products have a low risk of being abused and require moderate care in handling. Some foods such as cooked meat require special handling by the consumer to prevent spoilage that may not be 986 Handbook of Food Preservation, Second Edition obvious, and the consumption of such food may cause serious illness. Control measures: Controls are not necessary for food products that cannot be abused. Foods that have a low risk of abuse require moderate degree of control, while food products that require special handling need strict control measures. This is the next step after hazard analysis, which identifies the potential hazards that can threaten food supply and production. The presence of a control downstream should not be considered a reason to neglect controls in pre ceding steps. For example, wines are tested for pesticide residues prior to bottling and even then the grape grower has the responsibility to control the spray program. Any opportunity to eliminate or mini mize the occurrence of a hazard should not be overlooked. Emphasis should be placed on prevention of entry rather than detection after they have been introduced. This minimizes the risk of entry of hazards and avoids unnecessary inspection of raw ingredients on receipt. Therefore, prepro cessing techniques such as washing and sorting will be more effective in controlling hazards. The inspection of the finished product usually verifies the effectiveness of controls placed so far. For example, in a commercial process of smoked fish it is possible to identify many individual steps, but only three can be considered critical: salt penetration, smoking, and storage . This question refers to the use of control measures such as temperature control, visual inspection, or use of metal detectors at this step or subsequent steps in the food processing operation to control the hazard. If there are no control measures, the team should indicate how the hazard would be controlled before or after the manufacturing process (outside the control of the organization). Alternatively, the operation, process, or product could be modified to ensure that a control measure exists. Is this step specifically designed to eliminate or reduce the likely occurrence of the identified haz ard to an acceptable level? Examples of controls that are designed to eliminate or reduce the likely occurrence of a hazard include chlorination of water, pasteurization, use of metal detectors, cleaning procedures, etc. This question applies to process operations and is not appli cable to incoming raw materials. Could contamination with the identified hazard occur in excess of acceptable levels or increase to an unacceptable level? This question refers to the likelihood of the hazard having an impact on the safety of the product. If the contamination is not likely to represent a threat to human life, the response to this question is no. Will a subsequent step eliminate the identified hazard or reduce likely occurrences to an acceptable level? This question is designed to identify those hazards that are known to represent a threat to human health or that could increase to an unacceptable level, and which would be controlled by a downstream 988 Handbook of Food Preservation, Second Edition operation. If the response to this question is a yes,? it is necessary to identify the subsequent step that controls the hazard, thus proceeding to the next identified hazard. The questions given in the decision tree should be asked for each significant hazard at each process operation, including receipt and handling of raw materials. Uncontrolled application of agricultural chemicals, environmental pollution, use of nonpermissible addi tives, and other abuses of food along the food chain can potentially introduce or fail to reduce hazards related to food production, delivery, and service. Therefore, food safety programs designed to protect consumers have to meet several challenges: (i) the emergence of new pathogens and other hazards, (ii) the reemergence of pathogens and other hazards, and (iii) the threat of bioterrorism.
Hypoglycaemia is extremely dangerous especially when the blood glucose concentration is below 1 weight loss pills drugstore discount generic xenical uk. As a result the brain cells can be damaged or die weight loss pills kim kardashian cheap xenical online mastercard, causing cerebral palsy weight-loss supplement zantrex-3 cheap xenical 120mg free shipping, mental retardation or death weight loss pills for pcos effective 60 mg xenical. They are born before adequate amounts of glycogen, protein and fat are stored in their tissues. They have either not built up energy stores or have used up most of their energy stores before delivery because they have not been geting enough glucose from their mother. Infants that are not fed, either orally or intravenously soon afer delivery, rapidly use up their energy stores. Stressed infants, such as infants who are infected or who have sufered hypoxia, may be unable to convert their energy stores into glucose. Teir respiratory muscles are doing a lot of work and require large amounts of glucose to provide the energy needed for respiration. Before delivery these infants receive excess glucose across the placenta, especially if the maternal diabetes is poorly controlled. The higher the maternal glucose concentration, the more glucose the infant receives. At delivery the supply of glucose from the mother suddenly stops when the umbilical cord is clamped. Infants where there is a delay in the onset of feeding (infants who have not been fed) 4. The infant may be lethargic and hypotonic, feed poorly, have a weak cry, apnoea, cyanosis or an absent Moro refex. The infant may be jitery with a high pitched cry, a fxed stare and fsting, have abnormal eye movements or convulsions. Terefore, while some parts of the brain may be stimulated other parts may be depressed by hypoglycaemia. As a result, the clinical presentation of hypoglycaemia is very variable, making the clinical diagnosis of hypoglycaemia very unreliable. Whenever possible, use a refectance meter such as an Accu-chek or Glucotrend meter rather than reading the reagent strip by eye. Feed all infants as soon as possible afer delivery, especially preterm, underweight for gestational age and wasted infants, as well as infants of diabetic women. Both clear feeds orally and oral dextrose feeds should not be used in newborn infants as they are low in energy and may result in hypoglycaemia. Repeat the blood glucose measurement 30 minutes afer the feed to determine whether the blood glucose concentration has returned to the normal range. If it is still in the mild hypoglycaemia range, repeat the feed with an added 5 ml sugar (one teaspoon) per 30 ml milk and repeat the blood glucose measurement afer a further 30 minutes. The treatment of choice is to start an intravenous infusion of 10% dextrose (or Neonatalyte) at a drip rate calculated to give 60 ml/kg in the frst 24 hours. Infants older than 24 hours can be given a larger volume calculated for their age. To increase a 5% to a 10% glucose solution, add 10 ml of 50% dextrose to 100 ml 5% dextrose. If you cannot rapidly establish a peripheral intravenous line, insert an umbilical vein catheter so that intravenous fuids can be given. It is not advisable to inject a bolus of 25% or 50% dextrose as it is extremely hypertonic. If the blood glucose concentration still has not returned to normal within a further 15 minutes, give 5 mg hydrocortisone intravenously. As the volume of milk feeds are increased the rate of the intravenous infusion can be reduced. Never suddenly withdraw intravenous dextrose as this may precipitate hypoglycaemia, as commonly happens if the drip infltrates the tissues. Tereafer, measure the blood glucose concentration every 2 hours until 100 ml/kg milk feeds are established. Ten measure the blood glucose concentration as for infants with mild hypoglycaemia. The greater the risk of hypoglycaemia the more frequently the blood glucose concentration should be monitored. The risk of brain damage depends on the severity, duration and number of hypoglycaemic atacks. The risk of permanent brain damage is probably low if the hypoglycaemia is asymptomatic. Hyperglycaemia (hyper = high; glycaemia = blood glucose) is defned as a blood glucose concentration above 7. Some immature infants are not able to remove glucose fast enough from the blood stream. The stress of hypoxia or infection may increase or decrease the blood glucose concentration. A high blood glucose concentration results in a lot of glucose being excreted in the urine (glycosuria), which in turn may cause polyuria and lead to dehydration. Severe hyperglycaemia increases the risk of intraventricular haemorrhage in preterm infants. The raised blood glucose concentration usually can be lowered into the normal range by simply changing the intravenous solution from Neonatalyte or 10% dextrose to a 5% dextrose solution. Case study 1 A term infant is brought to a rural clinic afer having been born at home. This should be confrmed with a refectance meter if possible as reading a reagent strip by eye is not very accurate. Breast or formula feeds via a nasogastric tube or an intravenous infusion should have been started within an hour of delivery. Terefore, hypoglycaemia interferes with the normal functioning of the brain and may cause both depression of brain function resulting in a poor Moro refex and overstimulation of the brain resulting in jiteriness. If the milk feeds are tolerated and the blood glucose concentration returns to normal, then the rate of the 10% dextrose infusion can be slowly reduced. With immediate treatment there is a good chance that this infant will not sufer permanent brain damage. Case study 3 An infant weighing 4500 g is born to a patient whose diabetes was poorly controlled during pregnancy. Atempts to give 10% dextrose water via a scalp vein needle fail as the staf cannot fnd a suitable vein. Excessive glucose crosses the placenta to the fetus and this stimulates the fetal pancreas to secrete excessive insulin. What should be done if the hypoglycaemia cannot be corrected with an infusion of 10% dextrose? As this infant is at very high risk of hypoglycaemia due to the poor diabetic control and high birth weight, milk feeds should have been given straight away and a 10% dextrose or Neonatalyte infusion started. Once feeds are tolerated and the reagent strip readings are normal, the infusion can gradually be slowed. Measuring the glucose concentration in capillary blood with reagent strips 8-a the equipment that is needed 1. The desiccant keeps the reagent strips dry while the container prevents damage to the reagent strips by bright light. The higher the concentration of glucose in the blood the greater is the colour change. Allow the skin to dry and then pierce the skin with a lancet to obtain 1 large drop of blood. Most people prick themselves while removing the used equipment afer the procedure. Place a large drop of blood onto the two reagent areas, which are found on the printed side of the plastic strip. Wait exactly 60 seconds then quickly wipe the blood of the reagent area with a piece of coton wool. Afer a further 60 seconds compare the colour of the reagent areas by holding the strip against the colour chart on the container. The reagent area, closer to the end of the reagent strip that you hold, gives the more accurate measurement if the blood glucose concentration is in the normal or low range. The colour chart consists of 7 colour blocks ranging from yellow through grey-green to dark blue, which indicate blood glucose concentrations from 1 mmol/l (20 mg/dl) to 17 mmol/l (300 mg/dl) and above. For a more accurate measurement of the blood glucose concentration, a blood glucose meter (Refolux) can be used to read the Haemo-Glukotest strips.
