Microbial viability in preparations packaged for single use.

We evaluated microbial viability in preparations packaged for single use only which mandate that residual solution be discarded such as albumin and globulin preparations as blood products, preparations containing albumin (such as urokinase and interferon), fat emulsions, and a preparation containing fat emulsions (propofol). In most preparations, Serratia marcescens and Burkholderia cepacia proliferated rapidly at 30 degrees C. However, in globulin preparations containing 1-2.25% glycine to prevent protein degradation (Gamma-Venin P, Venilon-I, Globulin Injection, and Ahlbulin), no growth of S. marcescens and B. cepacia was detected over 24 h at 30 degrees C. For globulin preparations containing 1-2.25% glycine, the injunction to "Discard residual solution after the package has been used" in the package inserts can be revised to "It is possible to use residual solution within 24 h after the package has been used with storage in a cool place."

[Development of an inspection-supporting system using drug images for unit dose packages].

When inspecting unit-dose packaged drugs, there would be some possibility of inspection errors and ultimately dispensing errors due to pharmacist's incorrect memory of drug identification. Therefore, this study was aimed to establish a computer-aided system for inspecting drugs of unit dose packages more accurately and efficiently. First, we analyzed the identifiability of 5846 tablets and capsules using drug codes, in order to define an identification problem for unit dose-packaged drugs. It was shown that as much as 36% of the drugs do not have any codes, 4.0% of the code-marked drugs have identical codes with others, and that 9.7% of the drugs with codes on both sides of the surface share the same code with other drugs. Thus, it was clearly shown that in many cases it is impossible to identify pharmaceuticals exactly using drug codes only. On the other hand, it was indicated that approximately 80% of the drugs which were not identified with drug codes only, could be identified when additional information on drugs' color, size, form, and splitting line was provided. Therefore, in this study, we designed an inspection-supporting system to present promptly all the information necessary for the drug identification by displaying real drug images as linked with prescribing information on the monitor. Retrieval of prescription data from the order entry host was automatically performed by entering patient's ID number or by selecting a patient from the name list of patients at the inspection terminal computer. Moreover, the system was equipped with abilities to automatically check drug interactions and duplicate prescriptions, to provide various information of prescribed drugs and to monitor patients' drug history. We used the developed system and evaluated that it is a useful tool for accurate and efficient inspection of unit dose-packaged drugs. In addition, the quality of drug inspection increased by utilizing system functions such as checking drug interactions and providing drug information.

Effects of deceptive packaging and product involvement on purchase intention: an elaboration likelihood model perspective.

From an Elaboration Likelihood Model perspective, it was hypothesized that postexposure awareness of deceptive packaging claims would have a greater negative effect on scores for purchase intention by consumers lowly involved rather than highly involved with a product (n = 40). Undergraduates who were classified as either highly or lowly (ns = 20 and 20) involved with M&Ms examined either a deceptive or non-deceptive package design for M&Ms candy and were subsequently informed of the deception employed in the packaging before finally rating their intention to purchase. As anticipated, highly deceived subjects who were low in involvement rated intention to purchase lower than their highly involved peers. Overall, the results attest to the robustness of the model and suggest that the model has implications beyond advertising effects and into packaging effects.

Influence of concentrate composition and forage type on retail packaged beef quality.

The objective of this study was to determine the effect of type of conserved forage and concentrate composition on the quality of beef held in overwrapped (aerobic) or modified atmosphere packaging under simulated retail display for 17 d. Friesian steers (n = 45) were assigned randomly to one of five dietary treatments: 1) extensively fermented grass silage plus silage concentrate (EFS); 2) restricted fermented grass silage plus silage concentrate (RFS); 3) starch-based concentrate plus wheat straw (SC); 4) nonstarch-based concentrate plus wheat straw (NSC); or 5) zero-grazed perennial ryegrass plus grass concentrate (RYE). Meat quality was determined by measuring color, lipid oxidation (TBARS), alpha-tocopherol concentrations, and fatty acid composition. In aerobically packaged beef, there was a display x diet interactive effect (P < 0.001) on Hunter a* values, with steaks from the EFS group having higher (P < 0.05) a* values than all other dietary groups from d 6 through d 17. Moreover, during the last 12 d of display, beef from the EFS group had the lowest (P < 0.01) proportion of metmyoglobin (display day x diet; P < 0.001). Under aerobic packaging, the SC and NSC groups produced steaks with higher (P < 0.05) TBARS values than RFS, EFS, and RYE groups, which did not differ from each other (display day x diet; P < 0.01). The SC and NSC groups had higher (P < 0.05) oxidation levels than RFS, EFS, and RYE groups, which did not differ from each other. Beef from the EFS group had (P < 0.05) higher concentrations of alpha-tocopherol than from the SC, NSC, and RYE groups. Beef from EFS-fed steers had a higher (P < 0.05) proportion of saturated fatty acids than the SC and NSC groups. It was concluded that the method of grass conservation influenced beef color, whereas concentrate composition did not. Color of aerobically packaged beef was improved by feeding animals silage that had undergone extensive fermentation. Conversely, oxidative stability was decreased by feeding animals starch- and nonstarch-based concentrate diets.

Effect of various dairy packaging materials on the shelf life and flavor of pasteurized milk.

Milk from three different dairies (each a separate trial: 1, 2, and 3) was standardized to 2% fat and pasteurized at 92.2, 84.0, and 76.4 degrees C (temperatures 1, 2, and 3, respectively) for 25 s and packaged into six different packaging boards, [standard (A) milk boards with standard seam; juice boards with standard (B) and J-bottom (D) seams; barrier boards with standard (C) and J-bottom (E) seams; and foil (F) boards with J-bottom seam], resulting in 18 different treatments. Standard plate count (SPC) was used to test for microbial quality, and taste a panel was employed for flavor acceptability and difference on the milk stored at 6.7 degrees C at 1, 2, 3, and 4 wk. Statistical analysis of taste panel data showed that the flavor of milk samples A2, B2, and D2 deteriorated faster than the blind control (freshly high temperature, short time pasteurized low fat milk processed at 80.6 degrees C for 25 s). The flavor of milk packaged in standard (A) and juice (B and D) boards deteriorated at a faster rate than milk packaged in barrier (C and E) and foil (F) boards. Microbial counts showed that milk samples stored at 6.7 degrees C in trials 2 and 3 produced high SPC at wk 3 (ranges of bacteria in cfu/ml for trial 2: 9.9 x 10(1)-1.8 x 10(6) and trial 3: 2.5 x 10(5)-5.5 x 10(8)). In trial 1, high SPC began at wk 4 (9.9 x 10(1)-5.5 x 10(5) cfu/ml). Milk processed at 76.4 degrees C had the lowest bacterial growth rate, and milk processed at 84.0 degrees C had the highest bacterial growth rate. Different boards had no effects (P > 0.05) on the bacterial growth rates. It appeared that the lower the SPC of the raw milk, the slower the bacterial growth rate after 2 wk of storage. Milk samples stored at 1.7 degrees C maintained low SPC at wk 4, with counts of 0 to 40 cfu/ml for trial 2 and 0 to 200 cfu/ml for trial 3.

Effect of various dairy packaging materials on the headspace analysis of ultrapasteurized milk.

Milk from three different dairies (each a separate trial: 1, 2, and 3) was standardized to 2% fat and processed at 140.6, 129.4, 118.3, and 107.2 degrees C (temperatures 1, 2, 3, and 4, respectively) for 2 s and packaged into six different packaging boards [standard (A) milk boards with standard seam, juice boards with standard (B) and J- bottom (D) seams, barrier boards with standard (C) and J-bottom (E) seams, and foil (F) boards with J-bottom seam] resulting in 24 different treatments. A Shimadzu 15A series chromatograph equipped with a Porapak-P column was used to measure the headspace of the milk stored at 6.7 degrees C for 1, 2, 3, 5, 10, and 15 wk of storage. Gas chromatographic headspace analysis for sulfur compounds showed that hydrogen sulfide, methanethiol, and dimethyl sulfide were detected in milk processed at 140.6, 129.4, 118.3, and 107.2 degrees C. In addition, dimethyl disulfide was detected in milk processed at 140.6 and 129.4 degrees C, and dimethyl trisulfide was detected at 140.6 degrees C. Milk processed at 140.6 degrees C contained the most sulfur compounds. Samples C1, E1, and F1 retained the most hydrogen sulfide and methanethiol at 6 d of storage. Methanethiol appeared to be heat-induced. At wk 6, a slightly hammy or cardboardy flavor was detected for milk packaged in boards with standard seams (A, B, and C), and a slightly cooked flavor was detected for milk packaged in barrier and foil boards with J-bottom (E and F) seams. The hammy or cardboardy flavor intensified with storage time, and all of the cooked flavor dissipated at wk 10.

Gas-flushed packaging contributes to calcium lactate crystals in Cheddar cheese.

Gas-flushed packaging is commonly used for cheese shreds and cubes to prevent aggregation and loss of individual identity. Appearance of a white haze on cubed cheese is unappealing to consumers, who may refrain from buying, resulting in lost revenue to manufacturers. The objective of this study was to determine whether gas flushing of Cheddar cheese contributes to the occurrence of calcium lactate crystals (CLC). Cheddar cheese was manufactured using standard methods, with addition of starter culture, annatto, and chymosin. Two different cheese milk compositions were used: standard (lactose:protein = 1.47, protein:fat = 0.90, lactose = 4.8%) and ultrafiltered (UF; lactose:protein = 1.23, protein:fat = 0.84, lactose = 4.8%), with or without adjunct Lactobacillus curvatus. Curds were milled when whey reached 0.45% titratable acidity, and pressed for 16 h. After aging at 7.2 degrees C for 6 mo, cheeses were cubed (1 x 1 x 4 cm) and either vacuum-packaged or gas-flushed with carbon dioxide, nitrogen, or a 50:50 mixture of carbon dioxide and nitrogen, then aged for an additional 3 mo. Heavy crystals were observed on surfaces of all cubed cheeses that were gas-flushed, but not on cheeses that were vacuum-packaged. Cheeses without Lb. curvatus exhibited L(+)-CLC on surfaces, whereas cheeses with Lb. curvatus exhibited racemic mixtures of L(+)/D(-)-CLC throughout the cheese matrices. The results show that gas flushing (regardless of gas composition), milk composition, and presence of nonstarter lactic acid bacteria, can contribute to the development of CLC on cheese surfaces. These findings stress the importance of packaging to cheese quality.

Behavior of Listeria monocytogenes and Aeromonas spp. on fresh-cut produce packaged under equilibrium-modified atmosphere.

Storage experiments were conducted to follow the behavior of pathogens on fresh-cut vegetables (trimmed brussels sprouts, grated carrots, shredded iceberg lettuce, and shredded chicory endives) packaged under an equilibrium-modified atmosphere (EMA) (2 to 3% O2, 2 to 3% CO2, and 94 to 96% N2) and stored at 7 degrees C. As a comparison, fresh-cut vegetables were also packaged in a perforated high-barrier film (air conditions) and stored at 7 degrees C. In a first step, the shelf life of the vegetables in the two kinds of packages was determined by evaluating the microbiological quality as well as the sensorial quality (appearance, taste, and odor). In general, sensorial properties were faster in limiting the shelf life than microbiological criteria. The shelf life of the vegetables stored under an EMA was extended by 50% or more, compared with the air-stored vegetables. In a second storage experiment, the four fresh-cut vegetables were inoculated with a cocktail of psychrotrophic pathogens (Listeria monocytogenes, Aeromonas caviae [HG4]) and A. bestiarum (HG2) before packaging under an EMA and air at 7 degrees C. The inoculated pathogens were more influenced by the type of vegetable than by the type of atmosphere. No growth was detected on the brussels sprouts or on carrots (L. monocytogenes). Aeromonas spp. had a higher growth rate than L. monocytogenes on the shredded chicory endives and shredded iceberg lettuce at 7 degrees C.

Determination of thermal lethality of Listeria monocytogenes in fully cooked chicken breast fillets and strips during postcook in-package pasteurization.

Fully cooked chicken breast fillets and strips were surface inoculated with a cocktail of Listeria monocytogenes culture. The inoculation level was 10(7) to 10(8) CFU/g meat. The inoculated products were vacuum packaged and pasteurized at 90 degrees C with a pilot-scale steam or hot water cooker. After heat treatment, the survivors of L. monocytogenes were enumerated. No significant difference was found on survivors of L. monocytogenes between steam- and hot water-treated products. To achieve a 7-log10 (CFU/g) reduction, approximately 5, 25, and 35 min were needed for single-packaged fillets, 227-g package strips, and 454-g strips, respectively. The results from this study were subsequently verified by a computer model that could predict the thermal lethality of pathogens in fully cooked meat and poultry products during postcook in-package pasteurization.

Effect of reheating on viability of a five-strain mixture of Listeria monocytogenes in vacuum-sealed packages of frankfurters following refrigerated or frozen storage.

The purpose of this study was to assess consumer preferences for storing and reheating frankfurters and to use this information to assess the effect of product formulation and storage times and temperatures on the viability of Listeria monocytogenes after reheating of frankfurters. Individual links were inoculated with about 8.0 log CFU per package of a five-strain mixture of the pathogen, vacuum sealed, and stored at 4 degrees C for 3 and 15 days and at -18 degrees C for 30 days. Frankfurters formulated with and without 2% added potassium lactate were heated to a surface temperature of 60, 70, 80, or 90 degrees C for up to 8 min by submersing the packages in a thermostatically controlled circulating water bath. Surviving bacteria were recovered and counted by rinsing the contents of each package with sterile peptone water and plating this solution directly onto modified Oxford selective agar plates. In general, the results revealed that about a 5-log unit reduction was achieved by reheating to a surface temperature of 70 degrees C for about 2 min or 80 or 90 degrees C for about 0.6 min regardless of storage conditions or formulation. Product formulation did not appreciably affect the viability of the pathogen after heating; there was no appreciable difference in the number of cells surviving the heat treatment in product prepared with or without potassium lactate. These findings can be used to establish reheating guidelines for consumers to ensure that frankfurters, which may become contaminated with low levels of L. monocytogenes prior to packaging and after unpackaging, are adequately reheated prior to consumption.

Tamper-evident packaging requirements for over-the-counter human drug products--FDA. Final rule.

The Food and Drug Administration (FDA) is amending its regulations on tamper-resistant packaging to require that all over-the-counter (OTC) human drug products marketed in two-piece, hard gelatin capsules be sealed using a tamper-evident technology; to change the term "tamper-resistant" in the labeling of all OTC drug products to "tamper-evident;" and to specify that the required OTC drug product labeling statement must refer to all packaging features used to comply with the tamper-evident packaging requirements, including those on the secondary package, the immediate container or closure, and any capsule sealing technologies used. FDA is taking this action as a result of its continuing review of the potential public health threat posed by product tampering and to improve consumer protection by addressing specific vulnerabilities in the OTC drug market.

[The way for carrying medicine and its containers (IX): "Packaging insert in the Edo Period (1600-1867)"].

In the Edo Period a packaging insert for a patent medicine had two characters; the one was instructive and the other was advertising for taking a medicine. As there was not enough space in packaging for a patent medicine at thet time to describe the instruction for the medicine, history of the medicine, indication, how to take it, etc., they were shown on the back of the wrapping paper. Though some packaging inserts described volubly the merit of their medicines, most of them did not. It was influenced by a writer of the packaging insert.

Nursing attitudes toward oral liquid unit dose packaging.

Nurses' attitudes toward three types of oral liquid unit dose packages--glass, plastic and aluminum--were determined. Thirty nurses who previously had not used unit dose packaging on their units were asked to evaluate the three types of packaging. The nurses preferred both aluminum and plastic over the glass containers; there was no significant difference in attitude toward the plastic and aluminum packages.

[Packaging issues during the development of a medicinal product].

When it specifies the medicinal product, the article L.5111-2 of Code de la santé publique refers first of all to its "special packaging". The packaging, integral part of the medicinal product, does not only ensure its identification, it takes a decisive participation in maintaining drug quality and integrity; and moreover it facilitates its administration, therefore its good use, as well as its therapeutic observance. During the future drug development, the packaging is going to change, according to the development's phases, to lead to the final presentation which will be precisely described in the marketing authorization application. The packaging "cahier des charges" must be developed very early in order to guarantee drug quality and if needed, functionality of the device during storage. So it is a key element of drug preservation, which must be compatible with the market distribution. The pharmacist has to his disposal many kinds of material which can be used: glass, various plastic materials, aluminium, alumino-plastic complex, elastomers. Some examples highlight the industrial, security, prescription and administration aspects which must be taken into consideration during the development of a medicinal product in order to obtain the marketing authorization application, then to ensure permanence of drug qualities during its marketing.

[Determination of the overall migration of chemicals from the plastic packaging into the aqueous models of food using the EU methods].

Overall migration from food plastic packaging to aquatic food simulants (distilled water, 3% acetic acid) was determined according to the EU methods. Testing conditions (time and temperature) reflected normal use of tested food packaging. The overall migration studies using different food simulants (distilled water, 3% acetic acid) shows that the migration rate was very low, far below the allowed limit (10 mg/dm2). The high results of overall migration into 3% acetic acid (average 250.2 mg/dm2), markedly exceeding the allowed limit, was found in the case of multilayer film. It means that the multilayer film tested does not comply with the migration limit and it can not be used as a food packaging for the sour foodstuffs of pH below 4.5. Differences between the magnitude of overall migration into distilled water (0.5-1.1 mg/dm2) and 3% acetic acid are probably due to the presence of easy washable substances into the sour medium. From that reason the application of such food packaging materials must be limited.

Incident reporting in anesthesia: misidentification of propofol concentrations due to similarities in drug packaging.

We report three cases of misidentification of propofol concentrations due to similarities in drug packaging, which were identified by the incident reporting system. Incident reporting is an approach used to assess the incidence of adverse and potentially adverse events, established to manage the contributing factors and to develop appropriate strategies to prevent errors in anesthesia. Inadvertently, 2% propofol was administered instead of 1%, causing overdosage and prolonged anesthesia in two consecutive patients in the same operating room. The third case was a near-miss that occurred in another operating room of the hospital: a syringe containing 2% propofol instead of 1% was prepared by the nurse, but the anesthesiologist checked the concentration before the induction of anesthesia. The errors occurred due to the presence of similar propofol packaging in the operating rooms. They were the result of both human error because the anesthesia personnel forgot to check the propofol concentration, and system failure, due to the color code of the packaging. In our experience, incident reporting detected the recurrence of drug related errors. Therefore, a preventive strategy was put in place by eliminating 2% propofol packaging from the operating rooms. This paper highlights the need for a cultural shift in the way we collect information on incidents, and it is an example of effective improvement to prevent drug error by reducing the complexity of the system.

Household survey of child-safe packaging for medications.

In an investigation of the prevalence of safety packaging of medications, 131 randomly selected Minneapolis and St. Paul households with children were surveyed in 1985. Of the 1,953 oral medications in these households (mean was 14.9 per home), 43.3 percent did not have safety packaging. Over-the-counter medications were less likely to have safety packaging than prescription medications (over-the-counter 53.1 percent, prescription 25 percent). This high prevalence of medications without safety packaging in households with children could increase the risk of childhood poisoning. Strategies to reduce this potential risk are discussed.

Attitudes of private medical practitioners towards package inserts and other drug information sources.

One thousand questionnaires were distributed to private medical practitioners by representatives of a pharmaceutical company. The 221 respondents were predominantly male (91%) and most were trained at the Universities of Pretoria (37%), the Witwatersrand (22%) and Cape Town (19%) during 1960 - 1969 (24%) and 1970 - 1979 (45%). The majority (72%) found package inserts useful or extremely useful and 70% had consulted one during the previous week or on the day that they completed the questionnaire. Reasons for consulting the package insert, in order of frequency, were for information on untoward effects (64%), indications (33%) and mechanism of action (33%). Most respondents (71%) used the Monthly Index of Specialities (MIMS) more often than package inserts and 53% used the MIMS desk reference more often than package inserts. As regards additional regular information on drugs, 67% preferred a regular book to a loose-leaf system and 69% were prepared to pay for it. We are of the opinion that there is a need for information on drugs that would be complementary to current information systems, and that this should be a joint venture between Government and private enterprise, with the consumer being prepared to share the cost.
