Hazard analysis critical control point (HACCP) module was prepared for one of the most popular fast food momo (chicken momo and buff momo). For this, hazard analysis was conducted in eight different restaurants of Katmandu city by observing all the steps of preparation, monitoring time-temperature throughout the preparation process and collecting samples of different stages of these food. The samples were assessed for total aerobic mesophilic count (TAMC), total coliform count, total Staphylococcus aureus count, total yeast and mold count, detection of Salmonella spp. and Escherichia coli. During preparation of chicken momo, the highest TAMC, yeast and mold count, coliform and S. aureus count were found to be 2.8 × 106cfu/g, 2.1 × 103cfu/g, 1.92 × 105cfu/g and 3.4 × 103cfu/g respectively. While preparation of buff momo, the highest TAMC, yeast and mold count, coliform count and S. aureus count were found to be 2.82 × 106cfu/g, 1.9 × 103cfu/g, 2.1 × 105cfu/g and 2.8 × 103cfu/g respectively. These values and near to these values too were obtained from the samples of pickles, spices, raw momo, mixture of minced meat with spices and raw meat. The organisms originally present in the raw materials were subsequently transmitted to all the preparatory stages but was not observed after steaming and hence the final steamed product of both kinds of momo were free from microorganisms. Thus from the above findings, it was concluded that steaming was the main critical control point (CCP), which if done for proper time and temperature, can eliminate all the contaminating organisms.

The present study examined the prevalence of Salmonella spp. and the prevalence and quantity of generic (biotype I) Escherichia coli on carcasses or in pig feces at a pork processing plant operating under the hazard analysis and critical control point–based inspection models project (HIMP) program. The surfaces of carcasses were sponged on 10 separate days over a 30-day period at two processing steps: (i) immediately following exsanguination (100 carcasses), and (ii) after the carcasses were washed, eviscerated, and chilled overnight (122 carcasses). Feces were also collected from 60 of the 100 sponged, postexsanguinated pigs. Salmonella spp. were detected on 73.0% of the 100 postexsanguinated pigs, in 33.3% of the 60 fecal samples, and on 0.7% of the 122 chilled carcasses. E. coli was found on 100.0% of the postexsanguinated pigs and on 30.1% of chilled carcasses tested. The mean concentration of E. coli on carcasses was 1,700 CFU/cm2 immediately after the exsanguination step and 1.1 CFU/cm2 at the chilled carcass stage. Previous studies at this processing plant showed that the pre-HIMP baseline level of Salmonella spp. on the chilled carcasses was 0.8%, indicating that the present HIMP inspection system produced an equivalent level of bacteriological performance.

Critical Limits

In order to provide beef processors with valuable data to validate critical limits set for temperature during grinding, a study was conducted to determine Escherichia coli O157:H7 growth at various temperatures in raw ground beef. Fresh ground beef samples were inoculated with a cocktail mixture of streptomycin-resistant E. coli O157:H7 to facilitate recovery in the presence of background flora. Samples were held at 4.4, 7.2, and 10°C, and at room temperature (22.2 to 23.3°C) to mimic typical processing and holding temperatures observed in meat processing environments. E. coli O157:H7 counts were determined by direct plating onto tryptic soy agar with streptomycin (1,000 μg/ml), at 2-h intervals over 12 h for samples held at room temperature. Samples held under refrigeration temperatures were sampled at 4, 8, 12, 24, 48, and 72 h. Less than one log of E. coli O157:H7 growth was observed at 48 h for samples held at 10°C. Samples held at 4.4 and 7.2°C showed less than one log of E. coli O157:H7 growth at 72 h. Samples held at room temperature showed no significant increase in E. coli O157:H7 counts for the first 6 h, but increased significantly afterwards. These results illustrate that meat processors can utilize a variety of time and temperature combinations as critical limits in their hazard analysis critical control point plans to minimize E. coli O157:H7 growth during the production and storage of ground beef.

Acid Wash

A 2% lactic acid wash used in a large meat-processing facility was validated as an effective critical control point (CCP) in a hazard analysis and critical control point (HACCP) plan. We examined the microbial profiles of beef carcasses before the acid wash, beef carcasses immediately after the acid wash, beef carcasses 24 h after the acid wash, beef subprimal cuts from the acid-washed carcasses, and on ground beef made from acid-washed carcasses. Total mesophilic, psychrotrophic, coliforms, generic Escherichia coli, lactic acid bacteria, pseudomonads, and acid-tolerant microorganisms were enumerated on all samples. The presence of Salmonella spp. was also determined. Acid washing significantly reduced all counts except for pseudomonads that were present at very low numbers before acid washing. All other counts continued to stay significantly lower (P < 0.05) than those on pre-acid-washed carcasses throughout all processing steps. Total bacteria, coliforms, and generic E. coli enumerated on ground beef samples were more than 1 log cycle lower than those reported in the U.S. Department of Agriculture Baseline data. This study suggests that acid washes may be effective CCPs in HACCP plans and can significantly reduce the total number of microorganisms present on the carcass and during further processing.

ABSTRACT A total of 825 samples of retail raw meats (chicken, turkey, pork, and beef) were examined for the presence of Escherichia coli and Salmonella serovars, and 719 of these samples were also tested for Campylobacter spp. The samples were randomly obtained from 59 stores of four supermarket chains during 107 sampling visits in the Greater Washington, D.C., area from June 1999 to July 2000. The majority (70.7%) of chicken samples (n = 184) were contaminated withCampylobacter, and a large percentage of the stores visited (91%) had Campylobacter-contaminated chickens. Approximately 14% of the 172 turkey samples yieldedCampylobacter, whereas fewer pork (1.7%) and beef (0.5%) samples were positive for this pathogen. A total of 722Campylobacter isolates were obtained from 159 meat samples; 53.6% of these isolates were Campylobacter jejuni, 41.3% were Campylobacter coli, and 5.1% were other species. Of the 212 chicken samples, 82 (38.7%) yielded E. coli, while 19.0% of the beef samples, 16.3% of the pork samples, and 11.9% of the turkey samples were positive for E. coli. However, only 25 (3.0%) of the retail meat samples tested were positive for Salmonella. Significant differences in the bacterial contamination rates were observed for the four supermarket chains. This study revealed that retail raw meats are often contaminated with food-borne pathogens; however, there are marked differences in the prevalence of such pathogens in different meats. Raw retail meats are potential vehicles for transmitting food-borne diseases, and our findings stress the need for increased implementation of hazard analysis of critical control point (HACCP) and consumer food safety education efforts.

A field trial using cattle from a commercial feedlot was conducted to quantify the effect of duration of fasting and a temporary change in ration on the concentration of Escherichia coli biotype 1 in feces. A nested hierarchical design with repeated measures through time was used. Two groups of 20 British × European breed beef steers having reached slaughter weight (mean live weight 685 kg; SD 50 kg) were fed entirely on a high-energy ration typical of that used in the Ontario beef finishing industry or were switched for 4 days onto a high-roughage ration. This was followed by a period of fasting and water deprivation to mimic that which occurs prior to slaughter. Fecal samples were collected at 0, 24, and 48 h of fasting, and for each sample the total presumptive E. coli (biotype 1) CFU/g of feces was enumerated by spiral plating. Estimates of effect for the design factors were obtained by restricted maximum likelihood, and these were compared to robust counterparts obtained from generalized estimating equations. Results indicated that the ration, the duration of fasting, and their interaction had significant effects on total log E. coli concentration in feces. Cattle on the high-roughage ration for four days had a significantly lower initial log E. coli CFU/g of feces compared to cattle on the normal ration, but after 48 h of fasting they had a significantly higher concentration. It is concluded that while a temporary change in ration and duration of fasting does affect E. coli concentration in feces, these changes do not seem large enough to deliver a drastic improvement in beef carcass hygiene should they be incorporated in hazard analysis and critical control point (HACCP) plans for the preslaughter period of beef production.

The fate of Staphylococcus aureus in cook/chill systems before and after microwave-heating was determined, using inoculated beef loaf, dehydrated potatoes and frozen and canned green beans. These foods were prepared according to time and temperature recommendations of the Hazard Analysis Critical Control Point (HACCP) model for hospital cook/chill systems. Beef loaf was initially cooked to a mean end temperature (ET) of 66 C, potatoes were rehydrated and heated to a mean ET of 79 C and beans were not cooked initially. Products were covered and stored 24 h at 6 C. Products were portioned, 100 g/portions, stored covered 2 h at 6 C, and microwave-heated: beef loaf and frozen beans 20, 50, 80 or 110 sec; potatoes 25, 45, 65 or 85 sec and canned beans 20, 40, 60 or 80 sec. Number of S. aureus in products decreased as time of microwave-heating increased. When the mean ET of samples was approximately 74–77 C (HACCP model), microwave-heating did not consistently result in lethality of S. aureus. When time of microwave-heating in the present study was equal to time to reach 74–77 C in the prestudy, an ET of 74–77 C did not consistently occur in the food samples.

Lactic acid can reduce microbial contamination on beef carcass surfaces when used as a food safety intervention, but effectiveness when applied to the surface of chilled beef subprimal sections is not well documented. Studies characterizing bacterial reduction on subprimals after lactic acid treatment would be useful for validations of hazard analysis critical control point (HACCP) systems. The objective of this study was to validate initial use of lactic acid as a subprimal intervention during beef fabrication followed by a secondary application to vacuum-packaged product that was applied at industry operating parameters. Chilled beef subprimal sections (100 cm2) were either left uninoculated or were inoculated with 6 log CFU/cm2 of a 5-strain mixture of Escherichia coli O157:H7, a 12-strain mixture of non-O157 Shiga toxin–producing E. coli (STEC), or a 5-strain mixture of nonpathogenic (biotype I) E. coli that are considered surrogates for E. coli O157:H7. Uninoculated and inoculated subprimal sections received only an initial or an initial and a second “rework” application of lactic acid in a custom-built spray cabinet at 1 of 16 application parameters. After the initial spray, total inoculum counts were reduced from 6.0 log CFU/cm2 to 3.6, 4.4, and 4.4 log CFU/cm2 for the E. coli surrogates, E. coli O157:H7, and non-O157 STEC inoculation groups, respectively. After the second (rework) application, total inoculum counts were 2.6, 3.2, and 3.6 log CFU/cm2 for the E. coli surrogates, E. coli O157:H7, and non-O157 STEC inoculation groups, respectively. Both the initial and secondary lactic acid treatments effectively reduced counts of pathogenic and nonpathogenic strains of E. coli and natural microflora on beef subprimals. These data will be useful to the meat industry as part of the HACCP validation process.

Minas cheese is a typical Brazilian fresh cheese, manufactured by addition of rennin and CaCl2 to milk, followed by draining the curd. The intrinsic characteristics of this product make it favorable for growth of pathogens, including Escherichia coli O157:H7. The influence of the addition of a commercial mesophilic type O lactic culture to this product on the growth of this pathogen during storage at 8.5°C was evaluated. Eight different formulations of Minas cheese were manufactured using raw or pasteurized milk and with or without salt and lactic culture. Individual portions of each formulation were transferred to sterile plastic bags and inoculated with E. coli O157:H7 to yield ca. 103 or 106 CFU/g. After blending by hand massaging the bags, samples were stored at 8.5°C for up to 14 days. E. coli O157:H7 was counted after 1, 2, 7, and 14 days of storage using 3M Petrifilm Test Kit-HEC. Counts in samples without added lactic culture showed a 2-log increase in the first 24 h and remained constant during the following 14 days. Counts in samples with added lactic culture showed a 0.5-log increase in the first 24 h, followed by a decrease. These variations were statistically significant (P < 0.05). No significant variations (P > 0.05) were obtained for cheese samples manufactured with pasteurized or raw milk, with or without salt. Results indicate that the addition of type O lactic culture may be an additional safeguard to well-established good manufacturing practices and hazard analysis and critical control point programs in the control of growth of E. coli O157:H7 in Minas cheese.
